Try the OSZoo images.

http://www.oszoo.org/

There is also a debian developer that has some images.

My debian system has been down for a bit.
Let me run this first on FreeBSD and I'll give you my results later.

smeezekitty · 02-24-2010, 04:09 PM

I got a yaboot prompt now by not using the -M flag.
Now what?

Mr-Bisquit · 02-24-2010, 04:11 PM

Okay.
I've ran the basic script with the following options.

Code:

qemu-system-ppc -hda name-of-qcow-image.qcow2 -m 256

It's working.

I think you may need to build the image you want on the qcow image.

Create a second qcow image and then use that to build the other system.
You can also add an image and the cd/dvd path.

Skip using Prep or Zimage unless the argument calls for it.

I'm getting a initramfs error from the image but it is booting. This is the lenny image.

jefro · 02-24-2010, 04:19 PM

-m 64

That didn't look good.

smeezekitty · 02-24-2010, 04:20 PM

Ok now linux is booting but i have a kernel panic about not being able to mount the root partition.

Mr-Bisquit · 02-24-2010, 04:23 PM

Same panic.
Go to the debian forums and see what howto's there are on PPC booting.

Again, I'll post results that are relevant here for you.

Etch image mounts root file system along with other built-in options.

Problem seems to be in /scripts. You may need to add a boot argument when the open boot comes up.

Also, adding a screenshot of the boot process and the crash may help others help you.

You need to change the name of hdc to hda or to add root as hdc to the boot argument.

Script is looking for hda3 and not hdc3.

Unfortunately, I'm not good with ln + MAKEDEV.

How?

Mr-Bisquit · 02-25-2010, 04:29 PM

Do the following as the boot argument

Code:

qemu-system-ppc -hdc /path/to/image.qcow2 -m 256

It should work.
When I can, I'll find the video output arguments and help you.

smeezekitty · 02-25-2010, 07:26 PM

Its working now.
