GSOC qemu Boot Mac OS >= 8.5 on PowerPC system

[LightBulbFun]

I was wondering if my post on MR would show up on here heh (if anyone is wondering I did get 10.5.8 to boot in QEMU) be warned getting 10.5 going in QEMU is no easy task... (would of been much easier if mac99 emulation could boot OS X sadly it does not) I tried the same image in PearPC in 0.5 it hangs early on the boot process but in 0.4 it will boot to a desktop then the emulator randomly quits (some times it will quit just before the dock loads etc). BTW you can boot OS X 10.4 and 10.5 in virtual box you just have to remove the intel power management kext (VBox causes that to crash and take the system down)

Yeah; 10.5.x is a headache to get anywhere with. So do you recall what you did to get it working? I've got a Mini actually running it, so I can definitely generate a working bootable image, and apply any kext patches/extra fixes needed.

I've had the same experience as you regarding PPC 0.5/0.4 (redscorp got me slightly further than vanilla 0.4).

Regarding VirtualBox, have you attempted booting in post 4.3.6? I was booting both my 10.4.11 and 10.5.8 images on that, but any later version, they fail to boot, even with the kext fix and CPU reporting fixes. There's a long discussion about it on the VBox forums, and I haven't seen anyone able to get a guest booting yet on, say, VBox 5.0.2. I'm currently over-installing VBox between versions depending on which image I want to boot (10.10 doesn't do so well on 4.3.6).

[LightBulbFun]

well my VBOX install is 5.0 IRC and I had 10.4.11 booting on it fine (system profiler crashes but thats about it) its a stock install imaged from a real Mac all I had to do to get it to boot was nuke the intel power management kext heh

[adespoton]

Weird... which host Mac are you using? It could be something to do with the EFI changes between the old and new Core Macs....

[PeterHolbrook]

Those mentions to Tiger 10.4.11 running on VirtualBox are somewhat confusing to me. I interpret that is NOT the stock PPC Tiger, but a especially compiled version for Intel. Is this hunch correct?

[LightBulbFun]

yes this is tiger for intel (the first intel Macs shipped with special builds of tiger machine specific for the most part) here is a screen shot of tiger running in vbox (the host machine in this case is a quad core intel i7 haswell hackintosh using the clover boot loader but it also worked on my Mid 2007 Macbook pro and a Core 2 quad Xeon hackintosh using the chameleon boot loader)

[adespoton]

Tiger for Intel started at OS X 10.4.7; I've stuck the complete list of what versions run on what hardware here: http://apple.wikia.com/wiki/List_of_Mac_OS_versions

[LightBulbFun]

actually the first intel build of tiger was 10.4.1 then 10.4.3 with a full public release happening with 10.4.4 with the first core duo iMacs... (the Pentium 4 ADP machines used 10.4.1 and 10.4.3 I have 10.4.1 but cant get 10.4.3)

[adespoton]

Right; thanks for the reminder; that page only tracks public releases, but I forgot about the core duo release with 10.4.4 ([edit] "forgot" as in, I updated the 10.4.4 page years ago, but forgot to change the list page). Tiger was, of course, built for Intel from the initial betas and DP releases, but I don't add those.

So... which hardware are you running the 10.4 VM on?

[LightBulbFun]

like I said in my post with the screen shot in it... iv ran it on a MacBookPro 3,1 T7500 Core 2 duo, a X3220 Xeon Hackintosh and a Haswell Core i7 4700MQ Laptop hackintosh (to boot tiger on a Haswell system you need to patch the kernel but thats regardless if its running in VBOX or vmware...)

[adespoton]

Thanks; somehow I never saw that on the screenshot post. I'd expect it to run on the Core 2 duo; the Xeon and Haswell should require kernel patches like you've got -- I'm wondering if that's what let it work on yours but not on mine. I've tried on two Mac Haswells (unpatched) without success.

At least that points me in the direction of what needs to be modified to make things work again. Thanks

[LightBulbFun]

Just going to point out that Leopard does not require the kernel patching to boot (Just remove the apple intel power management kext) and that Tiger only needs the kernel patch on haswell (the X3220 Xeon is based off the Core 2 quad Q6600) http://landonf.org/2013/12/index.html (check this out for kernel patching it works on the client OS X too)

[PeterHolbrook]

So, is there any news at all regarding the progress of this project? Is there any likelihood to the scenario that someone (Cormac O'Brien?) will make booting of OS 9.2 possible in Qemu? Or is it more likely that we'll have to wait until at least the second half of 2016?

[kikyoulinux]

The git repo hasn't been updated since july 1st.

[adespoton]

I sent Cormac an email yesterday; haven't had a reply yet.

[DANADAX]

So... Anything new, at all?

[Cat_7]

Nope, nothing happening on this front.

Thanks for the good news. I've replaced the old openbios-ppc with the linked file and run

qemu-install/bin/qemu-system-ppc -bios openbios-ppc -boot d -cdrom os9.iso -M mac99 -m 512 -cpu 750

Sadly, the boot process keeps dying in the same place. Maybe the near future will bring further hope.

[adespoton]

That's VERY promising... Mark fixed the CUDA issues that were giving Cormac a headache!

This means that Classic and OS 9 should both boot far enough to load Macsbug now (no fully running OS yet AFAIK).

yep! and more importantly he fixed the issues that were preventing patch inclusion, and or breaking darwin/osx from cormac's patch set so hopefully these will be included into the official releases soon... bringing more exposure to the os9 on qemu issue!

spread the word!

[Cat_7]

The patches are meant for qemu. We need them applied to qemu before that new bios can be used in conjunction with a new qemu. I tried to apply all 13 of them to the source tree but failed.
Someone willing to give it a go?

Best,
cat_7

[gtxaspec]

perhaps they fail because the patches are already included in upstream git repo?

try compiling with no patches.

i would try but I am new to development on OSX and am currently trying to install all development tools to compile it.

[gtxaspec]

i was able to apply all 13 patches to the qemu master repo, but it still crashes on boot at the macos screen.

Excellent. The big test is: Can you boot OS X 10.4 on the same build? If you can, we're exactly where we should be, and development on enabling /functional/ OS 9 in qemu can continue
