darkhooda Posted September 11, 2005 Share Posted September 11, 2005 I've been trying to find a way to run Mac OS X x86 on an Athlon XP for a few days now, and I'm pretty sure that only Qemu and Bochs even have a chance of booting it, and I think Qemu has a better chance since when booting, it actually says SSE2 when OSX does the CPU check, though that might just because Bochs doesn't report it. I've tried it on both Bochs and Qemu, and here are the results (ahem, where they crash): Qemu Panic on left (using x86-64, gets farther than normal), Bochs stuck on right. One interesting thing to note is that on the bochsout log (you can download full log below), everything goes as normal until this area: 00130352172i[CLVGA] VBE enabling x 1024, y 768, bpp 32, 3145728 bytes visible 00130352172e[WGUI ] Sim window's client size(1024, 688) was different from the stretched size(1024, 768) !! 00130352172i[WGUI ] dimension update x=1024 y=768 fontheight=0 fontwidth=0 bpp=32 00142565245i[CPU0 ] RDMSR: Read 00000000:fee00900 from MSR_APICBASE 00142576072e[CPU0 ] RDMSR: Unknown register 0x1a0 00142577038i[CPU0 ] MOV_RdCd: read of CR4 00142583700i[CPU0 ] MOV_RdCd: read of CR4 00143795677i[PIT81] Changing GATE 2 to: 0 00143803136i[APIC0] CPU apicid=00: set timer divide factor to 1 ...

(repeats) Bochs crashes because of an APIC (likely interrupt error), and that's harder to solve than the ACPI error of Qemu. If anyone has information on that, please speak out. bochsout.txt Link to comment Share on other sites More sharing options...
cj Posted September 13, 2005 Share Posted September 13, 2005 why don't you try booting it with different platform= settings? Link to comment Share on other sites More sharing options...
darkhooda Posted September 13, 2005 Author Share Posted September 13, 2005 I'll try that, I completely forgot that I could do that since the last time I tweaked with Mac OS X on x86... Link to comment Share on other sites More sharing options...
joostpossemiers Posted September 13, 2005 Share Posted September 13, 2005 See this topic Bochs does NOT emulate SSE2 by default! In QEMU, you MUST chose a "Qemu x86_64 PC Based System", not the default. Someone got it working, i heard. Link to comment Share on other sites More sharing options...
darkhooda Posted September 13, 2005 Author Share Posted September 13, 2005 Yeah, I thought that Bochs doesn't enable it by default. Right now I'm going to just experiment with Qemu first, as I have heard from sources other than you that people have gotten it working on Qemu.

darkhooda Posted September 13, 2005 Author Share Posted September 13, 2005 I think I just found what I needed... Link to comment Share on other sites More sharing options...
TheElementWithin Posted September 13, 2005 Share Posted September 13, 2005 Amazing, I am going to try it on one of my older systems. Link to comment Share on other sites More sharing options...
darkhooda Posted September 14, 2005 Author Share Posted September 14, 2005 Just a note, the speed is TERRIBLE, I'm going to try it on a minimalist Debian netinst, but on Windows it takes something like 5 seconds (maybe more, but I only counted to 5 and then went to do something else) just to open up the Files menu. I don't think it's that much better than PearPC. After comparing my settings on Qemu with those over on the Qemu site, I found that the only thing I didn't do was the platform=x86.
