Get an IBM RS/6000 and install YellowDogLinux...

Then install MacOnLinux...

Q: Does MOL run on non-Apple hardware?

A: It does. MOL runs for instance on the Pegasos board, the Teron board and on AmigaOne hardware. In short, MOL should run on any PowerPC hardware (with the except of 601-based systems). However, the EULA of MacOS prohibits its usage on non-Apple hardware (it is of course perfectly legal to use MOL to boot a second Linux though).

:D

Oh I don't know, some of the big IBM machines may be just a tad quicker than the G5's ;)

OS X won't take advantage of more than two processors so running on a 32-way IBM server isn't much help. MoL does virtualization (the same way VirtualPC on x86 works) no say dynamic recompilation so you'd not see any more performance just because you have more processors.

The Power4 IS the IBM high-end performance chip right now. While the Power4 is designed for reliability, stability, and is incredibly quick - it's not designed to clock as high as the G5 will: in the near future you'll see G5s outpacing it's power4 grandfather. Of course IBM has the power5 under development. (as mentioned: power4 systems cost more than G5s anyway). You'd also be missing altivec on everything other than the G5/G4 - again that isn't going to help performance.

Pilsbury: Don't suppose you could get a few benchmarkts from your friend? ps7bench is popular right now, and if it sees a 3D card maybe you could run Unreal Tournament.

MacOnLinux doesn't do virtualisation at all. All the calls to the processor are native PPC calls. That's why it only runs on PPC....

From their site:

Mac-on-Linux makes it possible to run Mac OS (including OS X) under Linux/ppc. MOL is not an emulator but runs runs the OS directly without any CPU emulation. Moreover, NO ROM IMAGE is required.

It's worth noting as well that the Power4+ machines have a lot more cache than the G4 or G5 do...

Unless my understandy is way off, Virtual PC on x86 doesn't do emulation either: it does virtualization. Programs like soft mac, basilisk, fusion are all 68k emulators.

Virtual PC on Mac OS is equivilant to Fusion on x86, and MoL would be about the same as VirtualPC on x86.

Indeed, that's why I asked for benchmarks :)

Granted Power5 will be out Real Soon Now and by all accounts it's supposed to be disturbingly fast, but in the mean time it'd be interesting to see how well it works on whatever ibm gear we can get a hold of.

Just go out and buy you a Mac. You will be glad you did. :D

www.apple.com/store

I've got a 15" 1GHz PowerBook, a Dual 1.4 GHz G4 Cube, a 2.13GHz G4 (overclocked 1.4GHz upgrade card), a TAM, and have a Dual 2GHz G5 ordered - I think that's enough Macs to do me for now.

But, thanks for the suggestion... :yes:

I disagree - I think maybe you're confused on the terms?

MacOnLinux accesses the processor directly, using native PPC instructions.
That's what makes it virtualization as apposed to emulation.

I can't find anywhere specifically on the MoL site that calls it virtualization (they are very clear it is NOT emulation) however it's been pointed out several times on the MoL mailing list, the first i can find is here:

http://maconlinux.org/lists/mol-general/December00/0098.html

Also, wikipedia has it listed as a virtualization application on it's "list of emulators"

http://www.wikipedia.org/wiki/List_of_emulators

The BEST source of info I can find on the topic is this o'rielly interview with one of the NetBSD developers.

http://www.onlamp.com/lpt/a/3096

NetBSD runs everywhere, but it also runs "everything" (Linux, solaris, and BSD binaries, and now even os x binaries - sans cocoa/carbon/etc) through binary compatibility. He discusses the differences between binary compatibility, virtualization, and emualation so I think this is a pretty good resource.

So, it's nothing like VirtualPC in that respect.

VirtualPC on x86 runs exactly like that - which is what I've been saying all along. You could say VMWare if you'd prefer but it's the same thing.

EDIT: fixed bad quotes

haha you Mac freak!! :happy::

btw, 1.4GHz overclocked to 2.13GHz? that's :woot:: :woot::

    • As Total War turns 25, Creative Assembly is teasing a "new era" for the strategy franchise

      By LoneWolfSL · Posted

      As Total War turns 25, Creative Assembly is teasing a "new era" for the strategy franchise by Pulasthi Ariyasinghe Creative Assembly has now officially been making Total War games for 25 years. It was in June 2000 that the UK-based studio put forth Shogun: Total War for PC, with Electronic Arts publishing the ambitious project. With a quarter of a century now behind the series, the developer is now looking towards the "next era" of Total War. The studio will host its first-ever Total War showcase in December 2025, which is described as a "flagship video presentation unveiling what’s next for the franchise." Creative Assembly said that the showcase will have announcements for new games as well as content for existing titles, with developer commentary also happening regarding the future of the series. "We’re honoured and humbled to be one of the few video games that get the chance to celebrate such a huge milestone, and we want to thank colleagues past and present, as well as our fans for all the support," says Total War vice president Roger Collum. "2025 marks an exciting new era for the franchise as we reveal what’s next for Total War, and we can’t wait to celebrate throughout the year with everyone." Read an anniversary letter from Roger Collum regarding the studio's history, Total War beginnings, and more over here. Prior to the showcase, Creative Assembly will be hosting retrospective video interviews, developer livestreams, and more behind-the-scenes content regarding the series starting this August. There will also be multiplayer tournaments for fans, giveaways, Q&A sessions with developers, mod spotlights, and more events happening during this period. As the studio celebrates the occasion, a massive Total War historical games sale has just gone live on Steam. This has discounts of up to 75% across everything from the original Shogun: Total War to the latest entry, Total War: PHARAOH. The discounts will last until June 26.

      By leonsk29 · Posted

      ANY standard Windows PC, either desktop or laptop, can install the Copilot app, period, no NPU or Copilot+ certification required. I should know, I have it running on a 3770K (2011) Windows 11 PC and works perfectly fine. So, your laptop can definitely run it, too.
