Re: [OpenBIOS] Starting QEMU with OpenBIOS for Sparc32

[Armistead, Jason]

I should specifically add that I would like to get QEMU running under a
Windows environment.

I've managed to build QEMU using MinGW / MSYS etc as detailed in the QEMU
HOWTOs.

Now I just need to get that friendly Openboot-style prompt happening and
I'll be on my way.

Subject: [OpenBIOS] Starting QEMU with OpenBIOS for Sparc32

Sorry for such a newbie question

Can someone just give me a quick overview of the "right way" to start up
QEMU so that it will load the OpenBIOS firmware instead of PROLL, and how to
point QEMU to my Solaris installation CD image file.

Do I need any hacks / patches to QEMU to use OpenBIOS instead of PROLL ?

What debugging switches should I enable with QEMU to help me figure out why
things aren't working when trying to boot the SunOS 4.1.4 (Solaris 1.1.2)
installation CD ?

Is there a "best way" to build OpenBIOS to ensure maximum useful debugging
information is produced ?

If I'm repeating a whole lot of old questions, is there a FAQ for the QEMU +
OpenBIOS (Sparc32) combination that someone can point me to ?

Thanks

Jason

If you require to build OpenBIOS from sources in this environment you
should try to get a sparc cross compiler up and running (probably easier
with cygwin than mingw).

Generally you can start with using http://openbios.org/~stepan/proll.elf
as a replacement for the default proll.elf file that came with qemu.

NOTE: This one only works with -nographic, as the framebuffer handling
code keeps most OS boots hanging.
