AIX can INDEED boot from PowerPC.

Versions and so it depends.

AIX can also boot from PReP hardware, and PReP is emulated under QEMU.

If you need testing I have AIX from 4.1 to 6.1.

http://en.wikipedia.org/wiki/PReP
http://en.wikipedia.org/wiki/Common_Hardware_Reference_Platform

CHRP was intended to be the sucessor of PReP but mostly did not have alot of machines.


Even the Macintosh Server (that used AIX) was a PReP machine.

Power Macintosh can be seen as a derivate of CHRP, and BeBox areindeed no more than a PReP machine with a specific firmware.

Lauren,

Please be cognizant of the fact that yesterday was the first time I
downloaded, compiled, and ever tried QEMU, so I apologize for the
"ID-10T" questions.

BUG 1:

When you say that booting AIX 6.1 impels the requisite of emulating a

"CHRP with at least a POWER4"", are you saying QEMU cannot do this,or

I need to assert different command line arguments?

Qemu emulate a CHRP but the Apple implementation, I don't know ifAIX is able to manage it. I don't think Qemu emulates POWER4.

So I don't think you can run AIX6.1 with Qemu.

What requisites would booting AIX 5.3 impel?


At least POWER3, I think.

My goal would be to try to have access to both via an emulated
environment, if possible.

If the OpenBIOS will not work, what BIOS would work?


None...


BUG 2:

How do I get the OpenBIOS updates and integrate them into recompiling

QEMU, or can I just somehow get a compiled update of OpenBIOS anddrop

it in the correct QEMU directory?

I am not too familiar with SVN or its command structure either.


I can send you a binary... but I think it is useless.


V/R,

Stuart


Quoting "Laurent Vivier" <address@hidden>:

To whom it shall concern,
I have absolutely no time for mailing lists or to spend much timeonthis other than to report the bug, so please understand I am justhere
to report this, and have little time for continued testing of it. I
leave that to you, the developers.

I ran into two different bugs attempting to try QEMU 0.11, under
CentOS 5.3 64bit (fully updated), QEMU compiled from source
flawlessly, while under under VirtualBox on a Lenvo T400 laptop.

My goal was to try to boot an AIX CDROM from QEMU 0.11 (AIX 6.1), I
never got that far due to these bugs.


Bug #1:

It seems to complain about some 1MB BIOS file being missing or
dysfunctional, really I did not see any BIOS files that big, so, I
gave up with this type of boot. Then I tried below, "Bug #2", metwith
more problems, so I gave up entirely as I had no more time to play
with it.

To boot AIX6.1, you must emulate a CHRP with at least a POWER4.
Moreover, AIX6.1 needs the hypervisor support in OpenFirmware (which
is not the case of OpenBIOS).
Bug #2: never even tries to boot from CD-ROM and gives somewildly odd
error and display messages.
