[Qemu-devel] work needed to get solaris to boot under qemu-system-sparc

[Ben Taylor]

The question came up a little while back about getting Solaris (Sparc) to boot 
in qemu
under qemu-system-sparc.

I did a little work yesterday to find out that the boot process in hw/sun4m.c 
is really
kind of hard wired for a linux boot.   If there is no kernel or initrd, it 
drops right through.
In reality, if those variables aren't set, and the boot device is cdrom, 
shouldn't there
be some code to load the boot block in slice 3 of the cd/dvd?  At worst case, it
seems that we could probably extract the boot block and force qemu to load that 
with
the hope of getting a solaris/sparc on qemu started, since slice 1 of the 
cd/dvd is
the kernel and root directory structure.  Slice 0 is the install media.

Ideas?  I'm neck deep in the pool and have no idea where to start.
