Okay, I got passed the issue with formatting the root filesystem.
Apparently there are some limitations on the C/H/S parameters you use
for the disk that correspond with how UFS wants to format a new
filesystem. I'm not sure what exactly those limitations are at this
point, but, by adjusting a couple of the C/H/S settings when using
format to set up the disk I was able to get it to work correctly. So, I
now have Solaris 9 installed on qemu-system-sparc with OpenBIOS! I'll
probably go back to Solaris 8 as that one has a free binary license
while Solaris 9 is a commercial license, IIRC. I do own a Solaris 9
commercial license, but I like the free idea, better.
Anyway, now I'm on to an issue with networking - I've used the following
two qemu network parameter combinations:
-net nic -net tap,ifname=tap0
-net nic -net user
In the first instance, tap0 was configured on my Linux box and added to
my bridge br0. In both cases the Solaris system is unable to obtain a
DHCP address - the DHCP client times out. Not sure if I should be using
a different parameter set, or if this is another area that needs some
work either for OpenBIOS or qemu?

solaris 8 on sparc, webstart launcher crashing
by Brian Vandenberg
Greetings,
I'm unsure whether the issue I'm running into is related to
OpenBios, qemu, something buggy in this solaris distribution, or some
combination thereof. Feel free to redirect me as appropriate.
I'm able to install Solaris 8 (02/04) from the "Solaris 8 Software
disk 1" disk. I see a few different behaviors depending on what I
try:
1) boot from disk0:a without any special options:
After specifying a root password, it says "Starting Web Start
Launcher in Command Line Mode" and shortly thereafter says "The
Webstart launcher has terminated unexpectedly." with no further
details, except to say the machine will reboot after pressing enter.
2) Do the same thing, but with -v:
The result doesn't seem predictable. Sometimes it just hangs after
the "Starting ..." line, other times it dies with a variety of errors.
I'll try to summarize below:

For reference, I'm using a 3g qcow2 image. I originally formatted it
as a "SUN2.9G" in the format utility, but I let it autoconfigure the
partitions. partition '0' is root (1.18G), '1' is swap (149m), '2' is
backup (2.71g), and '7' is home (1.39g). There's overlap in the
cylinder ranges specified and the total size between those partitions
is larger than 3g ... but, I have no idea whether that's just a
Sun-ism, or whether I need to partition manually.
I don't think it's my partitions, though. The 'vol' directory doesn't
exist in my root before I try to get the webstart stuff to run, so I
think it's creating that directory and trying to mount an image to it.
Additionally, I'm starting qemu with:
./qemu_system_sparc -nographic -bios
/imgpath/openbios-sparc32_artyom.bin -hda
/imgpath/solaris2.8-img3.qcow2 -m 256 -net nic -net user -cdrom
/imgpath/solaris2.8/software_1of2.iso prom-env 'auto-boot?=false'
-snapshot
If anyone has a good idea, I'm all ears ... (or is it eyes?)

This patch for the scsi_options seems to work fine - system boots with
the patch applied and with the line removed from /etc/system.

[commit] r1041 - trunk/openbios-devel/arch/ppc/qemu
by repository service
Author: afaerber
Date: Mon May 23 00:29:33 2011
New Revision: 1041
URL: http://tracker.coreboot.org/trac/openbios/changeset/1041
Log:
ppc64: Don't set Kp bit on SLB
Since QEMU 81762d6dd0d430d87024f2c83e9c4dcc4329fb7d (Clean up
PowerPC SLB handling code) we never got to the ppc64 OpenBIOS banner.
According to Alex' debugging this is due to the Kp bit being set.
The code was supposed to be a 1:1 translation of the old mtsrin
code, which did not set Kp bit. So don't set Kp bit with slbmte.
Introduce a define for the shift, suggested by Alex.

[commit] r1040 - trunk/openbios-devel/config/scripts
by repository service
Author: blueswirl
Date: Sun May 22 18:39:48 2011
New Revision: 1040
URL: http://tracker.coreboot.org/trac/openbios/changeset/1040
Log:
switch-arch: remove non-standard "local" keyword
Remove the non-standard "local" keyword from within the crosscflags()
function. This was not necessary since the variables "host" and "target"
were not clobbered anywhere outside of the function, but the real
motivation is to support shells such as ksh93 that do not have the
"local" builtin like bash.

Re: [OpenBIOS] [Qemu-devel] [PATCH 01/27] Clean up PowerPC SLB handling code
by Andreas Färber
QEMU HEAD still uses a 32-bit binary for both 32-bit and 64-bit. That one uses mtsrin so will need the compatibility, it seemed affected, too.
OpenBIOS SVN HEAD (blob) uses slb* as linked to. We're in the preparation of 1.1 and I need to test it before we can update the QEMU binary. ;)
Sorry for top-posting, Android sucks.
