iMacs running Windows XP under Virtual PC are absurdly slow, unless you are just doing office software tasks. I am told that even on a G5, Virtual PC is no great shakes, speed wise.

I don't know if this has been replied to, and i don't have the time to read through 6 pages of replies to find out...

The latest version of Virtual PC was created before the G5 came out and doesn't take advantage of the new hardware. In fact, I think it might run slower on a G5, but I'm not certain. Another main reason VPC runs slow when doing anything other than basic tasks has to do a lot with the video cards emulated in VPC. The current version emulates some crappy 4 or 8 meg card. I'm pretty sure the upcoming version from Microsoft will take advantage of the G5 to emulate video better and speed things up quite a bit overall.

**EDIT**

Actually, VPC7 is already out :)

Made it to step 4 of Emon's guide.

Step 4: Now we are going to make a Hard Drive image where we will install OS 10.3. To do that run PPC_CFE.exe from C:\PearPC folder, click on File menu and choose Make Hard Drive Image..

I receive a nasty error, The application failed to initialize properly (0xc0000135). Click OK to terminate. Rebooting or cleanign out the temp files doesn't seem to do the trick.

-WinXP w/ SP2 slipstreamed.

-Firewall disabled

-Nothing running at startup

After installing .NET framework 1.1 and then running the .NET sp1 update, I was able to launch it just fine. Don't know if you wanted to add that to your guide or not :)

I'm also at the same point as Inplode. Nothing happens after clicking Start except the editor minimizing to my system tray. Even waited 20 minutes :(

Replace everything in that config file with this:

pci_ide0_master_installed = 1
pci_ide0_master_image = "hd_image.img"
pci_ide0_master_type = "hd"
memory_size = 0x20000000 ??? Set to 512MB Ram
ppc_start_resolution = "1280x1024x32"
redraw_interval_msec = 10
prom_driver_graphic = "video.x"
cpu_pvr = 0x00088302 ??? Remove this line if something goes wrong
key_toggle_mouse_grab = "F12"
key_toggle_full_screen = "Alt+Return"
pci_rtl8139_installed = 1
pci_rtl8139_mac = "de:ad:ca:fe:12:35"
pci_3c90x_installed = 0
pci_3c90x_mac = "de:ad:ca:fe:12:34"
pci_usb_installed = 1
prom_bootmethod = "select"
prom_env_bootargs = ""
prom_env_machargs = ""
nvram_file = "nvram"
pci_ide0_slave_installed = 1
pci_ide0_slave_image = "OSX_CD1.iso" ??? Whatever you named it.ISO
pci_ide0_slave_type = "cdrom"

Looks like this:

hey .. sorry guys .. I didn't check this thread for awhile ... I am amazed some people are actually using my program :D

@Callaway .. thanks .. I will add that info to the guide ( I thought everyone has .Net FrameWork 1.1 by now ..guess I was wrong :) )

and to everyone who are having problem starting up PearPC .. my program does nothing but calls pearpc.exe with the config file as the argument. So check your config file .. check if you have named your HD image right or not

That file is well documented .. if you guys are still confused about some parts of the file ..let me know.

i am having a problem and have been surfing the net looking on this....

i am using the mac osx disc that came with my sis's ibook (i dunno if it is the right disk or if i can use it, it says "mac osx install" on it...

[iO/IDE] <Error> invalid format <filesize isn't a multiple of 516096>

this only happens when i activate the cd.... (in the config file)

please help :(

Someone please help, i've gotten this to work before, but I can't figure out what I did differently before to get it to work for the life of me.. and nothing happens when i click start pearpc...with the file emon made..

here's my config and screen shot..

## PearPC Configuration File

##

## Start Resolution

##

## (clients that use video.x can change the resolution at runtime,

##  so this would be used only for starting up)

##

## format:  "(width)x(height)x(depth)"

##    or  "(width)x(height)x(depth)@(frequency)"

##

## depth can only be 15 or 32

##

## default: "800x600x15"

##

ppc_start_resolution = "800x600x15"

##

## Redraw interval (in ms)

## must be between 10 and 500

##

## If you set this higher, PearPC will spend less time doing redraws (and so run faster)

## but feel less responsive. You should adjust this to your computer speed and personal

## preference.

##

redraw_interval_msec = 100

##

## Key codes

##

key_toggle_mouse_grab = "F12"

key_toggle_full_screen = "Alt+Return"

##

## Loader

##

##

## Boot method

##  this can be

##  1. "auto", prom will boot the first bootable partition found (default)

##  2. "select", prom will show you a list of bootable partitions

##  3. "force", prom will load and boot the local file prom_loadfile

##

prom_bootmethod = "auto"

## Example of how to use "force":

#prom_bootmethod = "force"

#prom_loadfile = "test/yaboot"

#prom_env_bootpath = "disk"

##

## bootargs: don't change unless you know what you are doing

## machargs: set to "-v" to get a verbose startup

##

#prom_env_bootargs = ""

prom_env_machargs = ""

##

## This is needed if you want to boot Mac OS X

##

prom_driver_graphic = "video.x"

## This will adjust the position of the initial page table (don't change)

#page_table_pa = 104857600

##

## CPU Config

##

## Processor Version Register

## Defaults to 0x00088302

## Only change if you know want you are doing

## Altivec: G4 = 0x000c0000, G5 = 0x00390202 [ Do not use these values. They are not supported yet ]#cpu_pvr = 0x000c0000

cpu_pvr = 0x00088302

##

## Main memory (default 128 MiB)

## must be >= 64 MiB

##

# Remove the '#' sign front of your desired memory size

# 128 megs RAM

# memory_size=0x8000000

# 256 megs RAM

memory_size=0x10000000

# 384 megs RAM

# memory_size=0x18000000

# 512 megs RAM

# memory_size=0x20000000

# 640 megs RAM

# memory_size=0x28000000

# 768 megs RAM

# memory_size=0x30000000

# 896 megs RAM

# memory_size=0x38000000

#

# IO Devices

#

#

# PCI IDE Config

#

# Drive type will be set according to file extension:

#  .img: Harddisk (filesize must be multiple of 516096)

#  .iso: CD-Rom

# Or you can override this by specifying the type via

# pci_ide0_master_type / pci_ide0_slave_type

pci_ide0_master_installed = 1

pci_ide0_master_image = "C:\pearpc\pantherimage.img"

# pci_ide0_master_type = "hd"

pci_ide0_slave_installed = 1

# pci_ide0_slave_image = "C:\pearpc\panther.iso"

pci_ide0_slave_image = "C:\pearpc\pantherimage.img"

# pci_ide0_slave_image = "F:\"

# pci_ide0_slave_type = "cdrom"

pci_ide0_slave_type = "hd"

# pci_ide0_slave_type = "nativecdrom"

##

## Network

##

## Choose one of the cards

pci_3c90x_installed = 0

pci_3c90x_mac = "de:ad:ca:fe:12:34"

#pci_rtl8139_installed = 1

#pci_rtl8139_mac = "de:ad:ca:fe:12:35"

##

## USB

##

pci_usb_installed = 1

##

## NVRAM

##

nvram_file = "nvram"

post-107-1096656535.gif

pci_ide0_slave_installed = 1

# pci_ide0_slave_image = "C:\pearpc\panther.iso"
pci_ide0_slave_image = "C:\pearpc\pantherimage.img"
# pci_ide0_slave_image = "F:\"

# pci_ide0_slave_type = "cdrom"
pci_ide0_slave_type = "hd"
# pci_ide0_slave_type = "nativecdrom"

See ..you are using an .img file as a slave image. Thats should be an image file of your OS X CD. SO it has to be an .iso file. Also the type of the image has to be "cdrom" ...

unless .. you wanted to have a second hard drive.

    • Did you watch the keynote? It is way beyond what is described in this article. Looks interesting. Now it is time for them to deliver unlike what happened in 24.
    • It pretty much has to be compatible with MS Office or it is going nowhere. The rest of the world runs office including Europe. If it is not compatible it will not survive.
    • Incredible deal gets you free NVMe 512GB SSD with AMD AM5 B850 motherboard for only $150 by Sayan Sen Earlier this week we covered the story of an interesting PC case wherein you can build two full-size computers inside it as in it can house and run an AMD and an Intel system simultaneously. Speaking of building PCs, these are hard times to make one for sure as prices are often very high except during flash sales or discounts. If you are in the market for a 1080p gaming PC then Nvidia's 8GB RTX 5060 Ti is currently on sale for just $330 and you get the latest James Bond game too, for free. Speaking of which, right now there is another incredible sale going on as we can get a free 512 GB NVMe SSD from TeamGroup in the form of the G50 alongside the purchase of an AMD B850 socket AM5 motherboard for only $150 (purchase link under the specs table down below). Getting an AM5 motherboard now in 2026 will be a wise investment for sure, especially since AMD confirmed its commitment to support the socket till at least 2029. The MSI PRO B850M-P WIFI is a micro-ATX motherboard that is compatible with AMD Ryzen 9000 series processors. Since it is AM5, the motherboard works with DDR5 memory and includes MSI’s Memory Boost technology, along with EXPO and XMP support. Connectivity features include built-in Wi-Fi 7 paired with a 5G LAN solution. The board offers a PCIe 5.0 M.2 slot with MSI’s EZ M.2 Shield Frozr II thermal solution, that is said to help maintain SSD performance by providing ample cooling against overheating. The technical specifications of the MSI PRO B850M-P WIFI motherboard are given in the table below: The free TeamGroup T-FORCE G50 NVMe SSD is a PCIe Gen4 and as such it promises to deliver sequential read speeds of up to 5,000 MB/s, helping accelerate game loading, file transfers, and everyday computing tasks. The SSD features an InnoGrit controller and SLC caching technology to support consistent performance. An ultra-thin, patented graphene heatsink is included to aid in heat dissipation. The NAND flash is based on TLC which means it has plenty of endurance up its sleeve. The random performance may not be as amazing as other drives with DRAM though. Still it should be very good since it can access system memory via HMB to use it as its DRAM cache. The technical specifications of the TeamGroup 512GB G50 NVMe SSD are given in the table below: Get it at the link below: MSI PRO B850M-P WIFI AM5 AMD motherboard + Team Group T-FORCE G50 512GB SSD (free gift): $149.99 (Sold and Shipped by Newegg US) This Newegg deal is US-specific and not available in other regions unless specified.

    • RapidRAW 1.5.7 by Razvan Serea RapidRAW is a beautiful, non-destructive, GPU‑accelerated RAW image editor designed for speed and simplicity. It uses a lightweight (~30 MB), efficient code base built with Rust, React and Tauri. Ideal for Lightroom workflows, it offers rich editing tools—exposure, contrast, highlights, shadows, whites/blacks, tone curves, HSL mixer, dehaze, vignetting, film grain, sharpening, clarity and noise reduction—processed in real-time on the GPU. Features include intuitive masking (brush, linear, radial, AI-powered subject and foreground detection), generative edit layers (via ComfyUI), 32‑bit precision, and full RAW format support through rawler. RapidRAW also provides library management (folder navigation, ratings, metadata, EXIF viewer), batch operations, export presets (JPEG/PNG/TIFF), sidecar editing (.rrdata), undo/redo history, customizable UI themes, smooth animations, resizable panels, and preset copy/paste. A modern high-performance Lightroom alternative with polished UX and creative tools, RapidRAW brings powerful photo editing to photographers seeking speed, responsive GPU feedback, and streamlined workflows. RapidRAW v1.5.7 release notes: This update serves as a direct follow-up to the core architectural migration introduced in v1.5.6. While the transition to a more modular state management system marked a significant step forward for RapidRAW's stability and long-term maintainability, it also introduced several edge cases and regressions within the library and editing workflows. This release focuses on addressing those issues, with a particular emphasis on a complete overhaul of library performance to ensure smooth and responsive browsing following the refactoring. It also resolves inconsistencies in the copy-and-paste workflow and expands RapidRAW's accessibility by adding support for eight additional languages.

    • Thank god they got rid of the disgusting looking sidebars, and the corner radius looks much better, too. Two things I hated on day one, and never got used to.
