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? 

What requisites would booting AIX 5.3 impel?
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?


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 and drop it in the correct QEMU directory? 

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


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 time on
this other than to report the bug, so please understand I am just here
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", met with
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 some wildly odd
error and display messages.
