[Massimo Montecchi]

I have tried qemu from 0.11 to latest git (as of 11/09/2010), but if i want to use PREP PPC "machine" the error is the same:

qemu: hardware error: PowerPC 601 / 620 / 970 need a 1MB BIOS

This is a known issue, nobody has volunteered to update PReP emulation yet. The last partially working version was v0.9.1, using an OpenHackWare ROM file.

Depending on why you want to emulate a PReP machine, you can either try supplying some proprietary ROM file, or contribute PReP support to OpenBIOS [1].

I want to emulate PReP machine to be able to install AIX for testing purpose.

I will ask on openbios list.

[Andreas Färber (afaerber)]

This has long been fixed, at least for v1.0 I believe.
