PC ATI 5770/5870 cards flashed to work with Mac Pro


Recommended Posts

Thanks a lot +Boz for the terrific and detailed flashing tutorial.

I have a couple of questions I hope someone can help with about single/dual PCIe slot versions of the ATX card.

I?m thinking of having a go at an ATX ATI 5770 for my Mac Pro (now that Final Cut Pro X refuses to even download because I have an older non-OpenCL Radeon HD 2600 card installed).

I?m not a gamer, so my principal interest is in having an OpenCL compatible card in my Mac Pro. Obviously, a relatively powerful card is better, since the GPU will be doing a lot of the grunt work in rendering files. I?m also concerned about space and cooling, since I already have one PCIe slot occupied by a BlackMagic Design ?Intensity Pro? card (see http://www.blackmagic-design.com/products/intensity/).

I?ve had a look at your link to NewEgg, but I?ll be buying from the UK, so my choice is more limited, and usually more expensive. It seems that the more popular and common version is a single PCIe slot version of the XFX ATI 5770, which claims to have more efficient cooling and lower power consumption. It?s usually available as a Dual DVI with mini DisplayPort and sometimes including HDMI.

Do you know if your flashing procedure will work just as well on an ATX single slot version of the 5770?

If so, am I missing something in going for what seems to be a newer and more efficient version? Is there an argument for opting for the dual PCIe slot card?

Hi all, new to the forum here...

I can only get to about step #10 before I start to have problems!!!

After booting from my Win 95 boot disc, I see the DOS prompts but it says "No valid CDROM device drivers selected." What the entire screen says is:

CD-ROM Device Driver for IDE (Four Channels Supported)

© Sopyright Oak Technology Inc. 1993-1996

Driver Version : V340

Device Name : BANANA

No drives found aborting installation

Device driver not found: 'BANANA'.

No valid CDROM device drivers selected

A:\>

So I get to the point where I can enter in the "C:\" command, but once I hit enter it says: "Invalid drive specification"

Any ideas??? I'm trying to flash an ATI Radeon 5770 in a Mac Pro 1,1. Please help!

Woooohooo!!! Got it working. This is a great How-To guide, thank you so much for posting. Two things that I ran into:

1) I was having trouble getting into DOS so I used this as my boot disk fdbasecd.iso and it worked no problem (just press 1 at the first prompt, then 2 at the second prompt when you boot from a CD with this on it).

2) this is probably a super-noob thing, but it's been a long time since I've used any DOS commands so remember that to change disk drives, type:

C:

(or use whichever other letter your drive is called) and press Enter. And to bring up the directory, type:

dir

and hit enter. Again, this is probably ridiculously simple stuff, but may be helpful to someone out there.

Thanks again!!

I have the same problem... I can't detect any driver through MS-DOS.

I've followed the guide to setup the partition. On the top the "ATIFLASHHDD" formatted with FAT32, and below the second one with MacOs Journaled.

On the "ATIFLASHHDD" partition I've dumped the ATIFlash 3.89 file. The second partition it's empty.

The drive I used to make the partition was an external drive via USB. Maybe that was the problem.

Should I use an internal drive? I have none available for the moment.

I would appreciate all your help guys.

Hope to here from you soon.

Thanks a lot.

:)

I would appreciate your help and contribution.

Success!

Flashed ATI 5770 (possible for 5870) to work in Macs.. I'm using it in Mac Pro 3.1 (early 2008).

Apple upgrade is $280.. Newegg price for the card is $136. Saving $140.. PRICELESS smile.gif

This works on original Macs. Not for hackintoshes.

These are the cards you want to use for the seemless flashing:

5870 - http://www.newegg.co...&Tpk=XFX%205870

5770 - http://www.newegg.co...0-447-_-Product

Here's what needs to be done, not really a huge issue:

GUIDE:

1) Get the ATI 5770 or 5870 card linked above. I got the 5770 one.

2) You need to have a working mac graphics card in your system in PCI-E slot 1 just so you can do all this without problems and so you don't need a PC.

3) Insert the 5770 in your mac in PCI-E slot 2 and connect the power cable.

4) If you have an addition hard drive in your mac, or you have an empty HDD or the one you can tinker with, go to Disk Utility and create a partition on it as FAT. You can do this on your main OSX drive too I just don't like messing with Disk Utility and my main drive. But it's possible to just create additional partition there as FAT too.

5484414683_1ccc3239ed_o.png

5) Make a DOS boot disc.. The easiest way to do this is to simply go here: http://www.allbootdi...wnload/iso.html . Download Win95B bootdisk ISO ( http://www.allbootdi...5b_bootdisk.iso ) . Burn the image to an EMPTY dvd with Disk Utility.

5484414761_8d290f5677_o.png

5485009840_8cd90c0a89_o.png

6) Download ATIFlash 3.79 or later from here: http://www.techpower...Flash_3.79.html

7) Unzip the ATIFlash 3.79 to the FAT partition you created on your mac. We do this so your hard drive will be visible when you boot in Win95 DOS mode with the DVD.

5484425217_19252dbd7b_o.png

8) Put the DVD with Win95 boot disc in the drive and reboot your Mac.

9) Hold C to boot from the DVD disc.

10) Once DOS loads up and you see A:\ type C:\ to switch to FAT drive you created earlier.

11) Type DIR to list the contents of the drive to see if you see ATIFlash files. If yes, it's all good you are on the right drive, if no, you will need to double check if your hard drive is partitioned ok or if there's another drive letter available like D: or E: or G:.

12) Now, when you are at C: and you can see the ATIFlash.exe file on it after the DIR command, you type: atiflash.exe -i to list out all available ATI display adapters in your Mac (just in case you have something beside the 5770 you are flashing). The result should be something like a list view and it should tell you first the adapter number (usually the 5770 will be adapter 0) and the rom size (which should be 20000) and the GPU core will say Juniper.. if you see more then one adapter you have to make sure to note the adapter number for the 5770 Juniper card.

13) Okay, now we are going to backup your existing ROM.. in case something goes wrong. We do this by issuing the following command:

atiflash -s 0 XFX5770.rom 20000

You would call the file XFX5870.rom if you were dealing with the 5870 card. Let me just explain what's going on here.. the -s switch means it will save the rom from the card. the number is the adapter number you would see which is mention one step above. Then we have the name of the rom file and the size (which again should be matching the rom size in the info list we did earlier, and with this card should be 20000).

14) That's about it. Now we have the original ROM saved. We should do another DIR command now and check out to make sure that the rom size in file is 128KB (131 072 B). If you used the cards listed above you should get this without problems. If you don't, well read the "IF SOMETHING WENT WRONG:" paragraph at the end of this post.

15) Now, reboot to OSX and we will do one small modification to our rom file to make it work with the OSX and then we will reflash the card with that new one and that's gonna be it.

5485009756_151f0f08b3_o.png

16) Once you have rebooted, you will download the following file http://hotfile.com/d..._Tools.zip.html

17) Extract the content of the zip file in your home folder on your Mac. You should see 3 files: 5770_vervet_netkas.efi, 5870_vervet_netkas.efi and fixrom.py. These are the EFIs compatible with the Macs and the small utility tool that will fix your original card's EFI to work with Macs..

5485009778_d71359fcf4_o.png

18) Okay.. we are almost there.. Now copy the XFX5770.rom file you created with ATIFlash tool to the home folder as well (where the other 3 files you just download are) and make sure you still keep the original copy of the XFX5770.rom somewhere just in case something goes wrong and you need to re-flash your card to the original rom.

19) Mucho awesome! Now, in your home folder on your Mac (that's your username folder you click in Finder) you should have 4 files.. 3 of the flash helper files and 1 rom file.

5484452181_05d858a20a_o.png

20) Great, now all you have to do is run TERMINAL (you can start it up from Spotlight if you don't know where it's located) and copy paste these:

If you are flashing ATI 5770 paste this:

blocknum=`printf %d "'\`dd if=XFX5770.rom bs=1 skip=2 count=1 2>/dev/null\`"`
size=$(($blocknum * 512))
dd if=5770_vervet_netkas.efi of=XFX5770.rom bs=$size seek=1 conv=notrunc

If you are flashing ATI 5870 card, paste this:

blocknum=`printf %d "'\`dd if=XFX5870.rom bs=1 skip=2 count=1 2>/dev/null\`"`
size=$(($blocknum * 512))
dd if=5870_uakari_netkas.efi of=XFX5870.rom bs=$size seek=1 conv=notrunc

Once you have pasted into terminal window hit ENTER. Let it do it's thing and you should be good. I used 5770 approach.

5484458349_a066a7e466_o.png

21) Now, let's check if everything is going smoothly. Now you will open the XFX5770.rom (or XFX5870.rom if your card is 5870) from your home folder, with the Text Edit and you will search for string instance "mcuc". If you find 2 instances, everything is AWESOME. If not (if it's only 1 or more than 2), you will need to skip to "IF SOMETHING WENT WRONG:" paragraph.

5485060024_4c16fefaa5_o.png

5485060068_99b15b2e66_o.png

22) So far so good, you got 2 instances of "mcuc" and now you are ready for one small last step before you flash the rom back to your card.

23) Open terminal again and run:

python fixrom.py XFX5770.rom XFX5770.rom

(you would use XFX5870.rom if you were using 5870 card). After the small script finishes, you are READY TO FLASH again!

5485063138_5c0c4c4a82_o.png

24) Before we do flash it, let's rename the XFX5770.rom in your home folder to something like MAC5770.rom.

5485009800_78676de0ce_o.png

25) Copy it back to that FAT partition where you placed the ATIFlash file. Remember you should also have the old rom there so that's why we are renaming this one, so when you flash you are 100% sure that you are using the modified rom.

5484414747_fe05c6b746_o.png

26) Okay.. that's it.. now we gotta reboot into DOS again using that DVD and when you boot, you switch back to C:\ where the ATIFlash utility is and you run the following command:

atiflash.exe -p 0 MAC5770.rom

now let's analyze this again.. -p switch means that the BIOS should be written to the card. The is the adapter number of the 5770 card (or 5870) you have identified earlier when you used atiflash -i switch. And finally the name of the rom (MAC5870.rom would be the name if you are flashing 5870).

27) When the flash is done, you should see on the screen a message that says you need to reboot in order for VBios to be refreshed or something similar..

28) Power down the Mac. When you hear the bing, hold ALT key to boot into OSX.

29) You should see your ATI card now working natively in OSX. You are done.

5484069577_be5c9e78b3_o.png

This is guide was basically a more descriptive process recommeneded and outlined by jeanlain on netkas forums and thanks to the netkas and rominator efi mods to make sure you are working with your card's original EFI/BIOS and not using some custom ones that might cause issues and even kill your card.

IF SOMETHING WENT WRONG:

If something went wrong there are several issues that might have happened. You might not be using the card I recommended. Your cards are simply not as compatible as they should be and you will need to do some heavier modding to make them work. In order to find help and make things work, go here and read the steps that deal with your problem (if you have only 1 or more then 1 instances of mcuc in the modified rom file, or if your rom size is more or different than the 128k one mentioned in the tutorial.

Link: http://forum.netkas....php?topic=692.0

In case your card is not powering up or you think you messed something up, reboot the mac with the boot DVD we created and flash the card with the original rom. So it would look something like this: atiflash -p 0 XFX5770.rom. Power down your computer, turn it back on again and your card should be operating with the old ROM as originally created.

Hi all, new to the forum here...

I can only get to about step #10 before I start to have problems!!!

After booting from my Win 95 boot disc, I see the DOS prompts but it says "No valid CDROM device drivers selected." What the entire screen says is:

So I get to the point where I can enter in the "C:\" command, but once I hit enter it says: "Invalid drive specification"

Any ideas??? I'm trying to flash an ATI Radeon 5770 in a Mac Pro 1,1. Please help!

I have the same problem... I can't detect any driver through MS-DOS.

I've followed the guide to setup the partition. On the top the "ATIFLASHHDD" formatted with FAT32, and below the second one with MacOs Journaled.

Wow. This is why I am not stupid enough to buy a Mac for any purpose. That guide is ridiculously complicated and time consuming.

This guide is depricated..

Any ATI 5xxx series and I think even ATI 6xxxx series cards excluding the 6890/6990 will work out the box with OSX Lion.. I strongly encourage you guys to not use this guide and just upgrade to Lion. Then you can use most Nvidia and ATI cards these days right out of the box on your mac without the need to flash anything.

Marta, you don't have to flash the cards anymore.. just upgrade to OSX Lion if it's possible and your PC card will work right out of the box.

Hi guys, I'm desperatly looking for help with this exact subject, and this seems to be the only thread on the net that is specific to my current needs. So, sorry for drudging it back up.

I'm trying to install a PC HD 5770 into my Mac Pro 3,1 (2008), but it's not plug and play as this thread suggests for some reason. I'm not quite savvy enough to try a the flash suggested by the OP, and was hoping that it would 'just work,' since I upgraded to Lion for pretty much specifically this purpose.

When I install the card and boot the computer, I get nothing. I've waited about 10 minutes, and gotten nothing but a black screen. When I tried to boot off the old card with the 5770 still installed, it worked fine, but this is all that's showing up:

rGpeh.png

All software is up to date, and it seems that firmware is as well.

Any ideas? Help would be hugely appreciated - I'd rather spend the $$ on a new GPU for my gaming rig than on an old 5770 for my Mac :\

  • 5 months later...

First, this guide is NOT deprecated. I have a Mac Pro 1,1 running LION, and yes, out of the box it DOES work, but Steam and DVD Player don't work. Who knows what else doesn't work.

Second, because of this guide, I was able to flash my XFX HD-5770 to get everything to work properly. So yes, this is still an immensely useful guide.

Third, here are the answers to some of the issues others are experiencing on this forum. I just went through hours of figuring this out.

1. You MUST be running SNOW LEOPARD. I have no idea why, but these steps do not seem to all work under Lion. You're welcome to investigate why, but it was faster to install snow leopard on a spare HD then to try and figure it out (for me anyways).

2. Grab another spare/blank HDD, stick it in the Mac Pro. Remove all other drives. So you should have your Snow Leopard boot drive, and this second blank drive in your tower. No other HDD's.

3. Use Snow Leopard's disk utility to create 2 partitions as per Step 4 in this guide. Make sure you click "options" and select Master Boot Record.

4. Create the Windows boot disk as per step 5. I used a CD and it worked. I had zero success trying to create a USB thumb drive.

5. When you boot off the CD, you will get that stupid error some of you have mentioned, but it doesn't matter because you can type in "C:\" and it will work

6. The rest of the guide proceeds as outlined above.

For the record, I have flashed a ZNFC and a ZNDC version of the 5770 and it works.

EDIT: To effectively boot off the CD, hold "option" at restart and select the CD.... Holding "C" sometimes results in a frozen DOS prompt.

hey great tutorial,

but what i have to do in part 20) ?

i paste & copy this into the terminal, but this is the awnser from the pc:

mac:~ user$ blocknum=`printf %d "'\`dd if=XFX5770.rom bs=1 skip=2 count=1 2>/dev/null\`"`

mac:~ user$ size=$(($blocknum * 512))

mac:~ user$ dd if=5770_vervet_netkas.efi of=XFX5770.rom bs=$size seek=1 conv=notrunc

dd: bs must be between 1 and -1

what i have to do now ?

thanks!!

Hi Newbie here

i got the same problem like this ! anyone can help me about this ??

Hi Newbie here

i got the same problem like this ! anyone can help me about this ??

What version of OSX are you using.. as 9Charms said.. the problem is that I did this guide a while back and it was using Snow Leopard. Terminal stuff and especially OSX level commands do change or they add things or change how some things work.

I would really love to help, but without going with you through the whole process it's going to be difficult to see what's up.

But let's start here.

1. What version of OSX are you using

2. Are you on a hackintosh or a real Mac?

3. What is your ATI 5770 card you bought?

4. Can you post the size of your ROM from step 13/14

we'll see from there what's up.

Also.. another note for newer OSX (like Lion or Mountain lion).. to get your PC ATI 5xxx/6xxx to work, you need drivers (kexts) for it.

On OSX Lion you will probably need to look for original ATI 5xxx kext that comes with iMacs and install them with Kext Utility before you plug the ATI card in. You can look for some advices and forum posts about this on http://www.tonymacx86.com/

I am not sure what level of support and whether or not Mountain Lion comes with those drivers by default as I have not tried it but I read that people had success installing without too much problems.

Since Nvidia cards are much better supported on latest OSX versions, I strongly encourage people to go with Nvidia cards instead of ATI if you do have a choice.

5xx and 6xx cards work flawlessly on OSX (Lion and Mountain Lion). I have even dual GTX 580s now working on it. No flashing, no patching.. works great.

Just FYI.

1. What version of OSX are you using i am using 10.6.8 (mac pro 1.1)

2. Are you on a hackintosh or a real Mac? no real mac just trying to be macer :)

3. What is your ATI 5770 card you bought? XFX Radeon HD 5770

4. Can you post the size of your ROM from step 13/1 XFX5770.rom size 131 KB

1. What version of OSX are you using i am using 10.6.8 (mac pro 1.1) 2. Are you on a hackintosh or a real Mac? no real mac just trying to be macer :) 3. What is your ATI 5770 card you bought? XFX Radeon HD 5770 4. Can you post the size of your ROM from step 13/1 XFX5770.rom size 131 KB

Hi Boz/everyone,

I actually followed this nearly to a T, and have the same exact graphics card with the Juniper core (ZNFC). The only difference is I booted into Win safe mode CMD and flashed the card.

I've flashed it somewhat successfully, but it's reading display connector as blank (see pic).

Now, I've actually managed to get signal off of it in Windows bootcamp, but I can't get anything going in OSX. Any ideas?

Edit: I'm in SL 10.6.8.

Hello all. Big thanks to UNSTOPABLE for the post on flashing a XFX card to work in a Mac Pro 1,1. So here's my story:

I have two Mac Pros both 1,1 and about a year ago I used this quide to flash a XFX 5770 to work in MAC Pro A, the quide was PERFECT, it worked like a charm and I continue to have that card working. Last week I obtained another XFX 5770, actually three of them for I thought the first one was dead and I went through the same process as before, everything matched the guide except no video output from any of the ports I tried (2 DVD and the HDMI) so I flashed back the original ROM and tried again, still no luck and I have tried all three cards, which I know work on a pc after I have flashed them back to PC rom.

So after reading that LION sees these cards natively I decided to upgrade MAC Pro B to LION, since I tried both computers to perform the flashing. So now that MAC PRO B has lion I tried the cards, still no luck. Is it the fact that I have altered the Kernel extensions in the flashing is why LION can't use this card? If so, how can I get LION to see one of these cards in native form (Original PC form)? Is there a way to remove the Kernel extensions that were altered during the Flash, so That LION on mac pro B is "Clean"?

Any help would be appreciated..

Stuck with 3 XFX 5770 cards

Thanks

Hi guys, again that's to unstoppable for all his work :-)

I have a dell ati 5770 on the way.

Am I correct in thinking that if I upgrade my mac pro 1.1 10.6.8 to 10.75 then install the pc 5700 it will work without flash

But I will have no boot screen, Also DVD player will not work ( is there a fix for that) ?

If I had a 2nd monitor VGA would I see the boot screen?

Any help is much appreciated.

Best

Wow. This is why I am not stupid enough to buy a Mac for any purpose. That guide is ridiculously complicated and time consuming.

This is info on flashing firmware from one computer world into another computer world. You thought that would be easy?

Blame PC! Not Mac!

You prefer WIndows where a crash means you have to format your entire drive, reinstall windows, and reinstall your drivers, and your applications?

On Mac, IF you ever crash, you reboot and you're done!

Your DVD player has nothing to do with a graphics card.

If your DVD player does not work, buy a new one.

Flashing a GPU has nothing to do with your DVD player.

If you have a second Graphics card with VGA, for your second monitor, that will work. Not sure what you were trying to say.

Add a zero to that $140, and you're talking about Macs in general and not just a single hardware part in one.

If you are suggesting a Mac is a ripoff, why does US Military Nucular Submarines use Mac and not PC?

Why does the movie industry use Mac for Video Editing and special effects rendering?

Why are Mac the ultimate in graphics and audio editing?

Why are you here?

Trolling for a higher post count?

I've asked you a question in another comment which you haven't answered, so I'll ask it again: is it better now without "Europrats"?

From searching around online, user feedback on the company and ZimaOS is mostly positive, so we're off to a good start. In addition, I should probably point out that although they do not have a large portfolio of NAS devices, with just four of what they do offer, they seem to have covered everything from a relatively low-priced entry point with the ZimaBoard 2, right up to the high end, with the ZimaCube 2 Creator Pack that even includes an NVIDIA RTX PRO 2000. Anyway, as already mentioned, what we have today is the ZimaBoard 2 Starter Kit, and here are the full specifications: ZimaBoard 2 Model 832, 1664 CPU Intel Core N150 (4x E Cores/Threads, Max burst up to 3.6 GHz) TDP: 6W (Base) 10W (Max) Graphics Intel UHD Graphics 24 EUs (1.00 GHz) Memory 8 GB, 16 GB DDR5 4800MT/s non ECC SODIMM (soldered) Disk Capacity 60 TB (30 TB x 2) Supported RAID Types TRAID, TRAID +, RAID0, RAID1, RAID5, RAID 6, RAID 10 Storage 2 x SATA 3.0 6Gb/s Ports with Power Bootloader 32 GB, 64 GB eMMC Network 2x RJ-45 2.5 GbE PCIe 1 x PCIe 3.0 (via LPC) USB Ports 2 x USB-A 3.1 (5 Gbps) Display Mini-DisplayPort 1.4 (4K@60Hz) Hardware Transcoding Engine H.264, H.265, MPEG-4, VC-1 Maximum resolution: 4K (4096 x 2160); Maximum FPS: 60 Virtualization Intel® AES New Instructions Intel® Virtualization Technology (VT-x) Intel® Virtualization Technology for Directed I/O (VT-d) Size (H/W/D) 140mm x 83mm x 31mm Weight 0.4 kg (only ZimaBoard 2 device) Power 12v 5A Power Supply Warranty 1 year (Global) 2 Years (EU) OS ZimaOS v1.6.1 MSRP $339, $399 ($548.60) As you can see above, there are two variants of the ZimaBoard 2. The lesser variant has half the eMMC storage and 8 GB less RAM, although it also costs $60 less than the top variant we are testing today. The above pricing is only for the ZimaBoard 2. I put the MSRP of the Starter Kit next to it in brackets, although as of publishing, it is discounted to $534.50. The ZimaBoard 2 started life on Kickstarter and shipped to backers in August last year. It became available via the official website in late 2025 and Q1 2026. This hobbyist NAS contains the still relatively new N150 Intel CPU released in the first quarter of 2025, with support for DisplayPort 1.4, HDMI 2.1, although in this case, the memory is integrated into the board itself, so it will not be possible to upgrade or expand the amount. It also supports AV1 decoding, as well as H.264, VP8, VP9, H.265 (8 bit), and H.265 (10 bit). The different capabilities in the Alder Lake-N (and Twin Lake) series are listed below. Processor E-cores L3-cache Turbo clock GPU GPU-clock TDP Intel N355 8 6 MB 3.9 GHz 32 EUs 1.35 GHz 9 W Intel Core 3 N350 3.9 GHz 1.35 GHz 7 W Intel Core i3-N305 3.8 GHz 1.25 GHz 9 W Intel Core i3-N300 3.8 GHz 1.25 GHz Intel N250 4 3.8 GHz 1.25 GHz 6 W Intel Processor N200 3.7 GHz 0.75 GHz Intel N150 3.6 GHz 24 EUs 1 GHz Intel N97 1.2 GHz 12 W Intel Processor N100 3.4 GHz 0.75 GHz 6 W The CPU is part of the Twin Lake series that sits near the bottom of the N-series, designed for low- powered systems and entry-level laptops, and as such has a base level TDP of just 6W. As I have noted before, we are seeing another NAS with a great amount of RAM. It's important to mention that the ZimaBoard 2's memory is integrated into the base board (which is why they have two variants of it). As a reminder, up until a couple of years ago, it was commonplace to only get 2 or 4GB max on a flagship Synology or QNAP home NAS. Ever since the likes of TerraMaster and more have entered the market with ample RAM sizes included in their NAS offerings, it has gone a long way in forcing the hands of the traditional makers to up their game a bit. First impressions The Starter Kit came in one outer box with several packages inside it (shown above). I forgot to take pics of it because when it arrived, it wasn't clear what was inside, and I had to confirm with my contact that I received the entire Starter Kit. In the box ZimaBoard 2 ZimaBoard 2 HDD Expansion Bracket + PCIe card frame Zimaboard Mini DisplayPort Male to HDMI Female Cable 4K 60Hz Zimaboard PCIe 3.0 x4 to Dual NVMe M.2 SSD Adapter Card Quick guide [full online guide] Limited warranty notice Screws Design Where to start? You'd be forgiven for mistaking it as an SSD enclosure if not for all the ports on it. It is completely made out of metal, and the top is an entire heatsink. It has a premium feel about it, but it definitely looks like a hobby device. As you will see, the completed build looks like it belongs in a server or meter closet rather than as a showpiece on someone's desk. On what I am calling the rear, there's a Mini DisplayPort (1.4), two 2.5 GbE ports, with Type A 3.1 USB ports, and then the barrel connector port. Around the front, there are two SATA6 ports with a power connector in the middle. Left side Right side One side is completely free of ports. On the other there's a slit that allows for the feed of a CPU fan cable, and a PCIe 3.0 X4 slot. Top Bottom The top is entirely made up of a heatsink except for the extended height for the I/O on the rear. Around the other side, you can find the ZIMA branding and some regulatory information stamped near the bottom. As you may see from the bottom of the ZimaBoard 2, it scratches quite easily from just moving it around on my Ikea island. Teardown Before we get started, let's have a look at this thing on the inside. The steps to get to the board are as follows: Remove the four smaller Torx screws on the bottom of the ZimaBoard 2; Remove the four larger Torx screws on the sides of the device; Carefully unstick the CMOS battery from the PCB; Remove two Phillips screws on the PCB; Lift out the PCB. Yes, as you can tell from the instructions, you need three different tools to remove Torx and Phillips screws (10 in total), and unhelpfully, one of the screws is located under the CMOS battery, which is stuck onto the PCB. Building Now comes the fun part. Because the ZimaSpace website does not provide any guidance on how to put the Starter Kit together. They only have guidance for connecting the CPU fan. However, they did upload a video to their YouTube channel that shows the entire process. To install the fan, first remove the four screws on the bottom of the ZimaBoard 2, then on the inside, there is a CPU FAN connector where you can attach the fan, reattach the ZimaBoard 2 frame, and feed the fan cable through the provided slit. Then remove the nearest screw on the side and attach the fan frame to the side of the device using the same screw. ZimaBard 2 screws Aligning the screws Bottom view Remember those four screws we removed to access the CPU FAN? Longer screws are provided in the box with the HDD Expansion Bracket, which is what you will now need to attach the ZimaBoard 2 to it. Helpfully, the orientation on how to attach it is made obvious when the frame can only be screwed on at the same overall length as the ZimaBoard 2. If you do it the wrong way around (which is what I did initially) one side hangs off the frame, and it becomes difficult to attach the PCIe Adapter Card cable. PCIe card frame Other side PCIe slot connector Next, it's time to attach the PCIe card frame, which is fastened with the help of 3.5-inch SATA HDD (3 screws). These are toolless screws that you can just use your fingers to fasten them with. Then it is time to connect the provided PCIe cable with the slot connector on one side of the ZimaBoard 2, feed it through the bottom of the HDD frame, and fasten it with two standoffs. Both bracket options 2280 standoffs with 2x 4TB MP44Q The PCIe 3.0 X4 card comes with a short bracket option, handy if you decide to place it inside a different NAS or rack server, but here we need the long bracket. Oddly enough, the M.2 standoffs were preinstalled into the 22110 position, but extra standoffs are included in the box, which I installed at the 2280 position for our use. I added a couple of MP44Q M.2 PCIe 4.0 SSDs (2 x 4TB) that can be availed on Amazon for $478.99 (the lowest price for 3 months) that TEAMGROUP supplied us with Then we have the almost completed build, you just need to push the card into the PCIe slot. Unfortunately, IceWhale Technologies did not provide a screw for the PCIe card frame (this is also apparent in their own video). Here it is at several different angles, with the last pic showing the SATA Y-Cable connected to the two WD Red Plus 4TB drives. Setup and Usage Next, you connect your cables to the I/O, and the ZimaBoard 2 powers on automatically, as there is no power button on the device. Power is controlled through the Settings in ZimaOS. BIOS The ZimaBoard 2 includes an Aptio BIOS from American Megatrends [1, 2, 3], and you can setup pretty much everything here including the boot order, which is locked to the UEFI OS, however above that choice you can enable or disable booting to a SATA/USB bootloader so this would still allow you to switch to an alternative bootloader and boot from it, or disable it to instead always start from the first disk with an OS installed on it. Initial Setup Upon connecting to the LAN and booting up, the ZimaBoard 2 can be reached by navigating to the IP address (shown if you have a monitor connected), or you can find it using the ZIMA Client desktop application, which is essentially a Zima device finder. Initializing the ZimaBoard 2 The ZimaOS setup process is pretty straightforward, through a wizard, and in full above, it basically consists of setting up an account and some handy tips, and that's that! Post Setup (ZimaOS update) Upon first boot, you are alerted that there is a ZimaOS update from 1.5.0 to 1.6.1, which I applied; the full process is shown above with the changelog. ZimaBoard 2 Storage Setup Next, it is time to set up the storage. ZimaOS actually throws everything onto the eMMC flash drive; it is also the default location of AppData, which is definitely something to be wary about, as the 45GB available storage could fill up quickly. HDDs I first attempted to create a Storage Pool using the two 4TB WD Red Plus NAS drives, and got an error message: After several attempts and then looking online, I discovered it was a bug with ZimaOS where the fix was simply to reboot ZimaOS and then try again, this time I was able to create a RAID mirror using the two drives. SSDs I did the same for the SSDs, as you will see in the above gallery, when I created the second Storage Pool, it only allowed me to select available drives. ZimaBoard 2 AppData ZimaOS comes with an App Store that includes a repository of almost 400 apps, so you will be able to find most of what you'll need for a NAS (although after a quick search, I wasn't able to find a Surveillance Manager), and now comes the important part: moving the default AppData location off the 45GB eMMC and onto a larger volume: Open Settings Then Apps Then, in the Select a new location field, click on the new Storage volume you want to move it to (in my case, the Apps Storage Pool), which is the SSD RAID mirror. Confirm the Migration warning Be praised! You can also do this for Docker (which by default installs onto the 45GB eMMC flash drive) and the User database. Plex Setup Next, I tested the configuration by installing the Plex Server app from the App Store. The library folders must already exist (which I placed into the Storage Pool). Plex Server setup is straightforward and requires very little configuration. In my case, all I had to do was add the media path I just created, which you can also browse to using the folder icon in the path field. In addition, you can now map the new Media library in Windows Explorer using the Zima Client. Oddly enough, it is not possible to access the ZimaBoard 2 over the Network Neighborhood; you must map drives using the client, which is shown in the last image in the above gallery. I watched one of my Blu-Ray rips, which is Dolby Vision with Dolby Atmos, and the content played fine with no stuttering or buffering, which is what anyone needs in this scenario. ZimaBoard 2 Zima Client mobile app There's also a client for mobile. It is pretty barebones, as shown in the above gallery, for example, the Apps screen launches the WebUI for that app, and the Backup must be done manually. On opening Backup, you can select internal storage folders on your phone to backup to the ZimaBoard 2's storage, and although this is constantly scanned, the backup action itself must be manually triggered. There is an option to allow foreground backup (last image in the above gallery), but this basically means the queued backup gets triggered when you manually open the app. Benchmarking SATA PCIe 3.0 X4 A CrystalDiskMark test on a mapped network drive from within a Windows 11 25H2 PC (image above) connected over a 2.5 GbE was well within acceptable ranges. Writes were generally better on the SSD RAID mirror. SATA PCIe 3.0 X1 I also ran the NAS Performance tester, which tests the link speed performance. As you can see, it pretty much maxes out the 2.5GbE connection. Of course, you can also opt to bond the two 2.5 GbE connections for a bit more umph, but I didn't do that. Thermals Top PCIe card SATA HDDs Next, I measured some hotspots while playing content on Plex. It's fair to say this will perform better than a NAS that is enclosed in a metal or plastic case, as almost everything storage-wise is exposed! Anyway, the ZimaBoard 2 did not break a sweat with Plex streaming or disk benchmarks. ZimaOS Factory Reset ZimaOS does not include a factory reset option. Instead, you have to download the ZimaOS image and flash it to the eMMC manually. The flashing process is shown in the above gallery. The steps to do so are listed below: Download the ZimaOS image here; Open BalenaEtcher (Run as Administrator) and select the image; Select your inserted USB drive (min 8 GB) Flash to it; Connect your USB drive, monitor, keyboard, USB hub (optional), mouse (optional), and network cable (recommended) to the ZimaBoard 2; Connect power and press F11 continuously; Select your USB drive starting with UEFI in the boot device menu; Press Enter on the Install ZimaOS option; Select /dev/mmcblk0 (MMC) flash drive as target; Confirm with (three times) to wipe the target disk; Wait a couple of minutes while ZimaOS installs; Remove the USB drive and confirm with a reboot; Your ZimaBoard 2 has been factory reset. However, you don't have to stick with ZimaOS, in fact the company also offers official CasaOS images, that are based on Debian; or as they say themselves, put anything you want on this "hackable single board server" it's up to you. Conclusion I had a lot of fun putting this together. I've custom-built all my own PCs and servers since the 90s, and this is the first time I have had to put a NAS together. Even if the actual base ZimaBoard 2 was already a completed build, it still feels pretty custom. I just wish that IceWhale Technology included a getting-started guide in the box for the Start Kit, which would have really completed this kit. Instead, I had to search for the official video on the YouTube channel to make sure I wasn't doing anything wrong. So who is this for? Definitely the hobbyist who is comfortable building their own PC and servers. It also has a much smaller footprint than its nearest equivalent (in terms of specs), like the Beelink Me Pro, which is another NAS I will be testing soon. Although the Beelink does not come with the PCIe 3.0 X4 expansion, the ZimaBoard 2 Starter Kit suddenly looks to be a great bargain, even if it only offers the two 3.5-inch bays over the four in the other example. It makes a lot of sense to use Intel's N150 chip inside a NAS; it is more than capable of doing what the ZimaBoard 2 is intended for, media streaming and backup. It also looks like the IceWhale Technology staff are quite active in the official forums helping people with issues they come across with ZimaOS and the devices, peer support seems to be good as well, I was quickly able to find why I was not able to create a new Storage Pool in ZimaOS v1.6.1 even though that is quite a serious bug, hopefully it will be fixed in the next update. If you are comfortable with the command line and Docker, you'll be fine. You can do great things with this hardware. This was my first time with ZimaOS. It seems a bit barebones in comparison to the likes of Synology DSM, TOS, and UGOS, but it has a ton of apps to get you started with your home or small business NAS. Where to buy As of publishing, IceWhale Technology is running a discount of up to 5% for the Starter Kit. If you opt to get just the ZimaBoard 2 itself, it does come with a SATA Y-Cable, so you will be able to connect up to two 3.5-inch HDDs to it.

    • It's in the Insider's group so yes it's technically beta, though these days it's hard to see much of a difference unless you opt for the most extreme beta builds, which I don't. When I moved here from the Release Preview channel I did so primarily because I wanted to see how well the restored taskbar functionality (restored from Win10, and earlier) is working and whether it was time to finally abandon SAB--and it is--working fine, so far. Not as polished as SAB, but it'll do for me.
    • I've been using MWB Premium for a number of years so that along with Windows updates and updated browser should be fine. Thanks for that.
