by G 3
I have begun doing work with OpenBIOS. I was wondering if it is
possible to compile OpenBIOS for PowerPC on Mac OS X? If not, what
Linux distro should I use? Any advice would really help.

Solaris 9: failed boot with strange device names
by Mark Cave-Ayland
Hi all,
So given that the Fcode evaluator is sorted for Solaris 10, I thought
I'd try my original Solaris 9 disk image again and was surprised to find
that it didn't boot.
Further investigation seems to show that strangely encoded device names
are being passed into cif-open which is failing:

00000000ffe360f8: (semis)
It looks as if a special type of device-specifier is being passed into
cif-open consisting of a device and argument, a comma, then the actual
filename required with /s replaced by |s.
Is this some kind of special syntax that needs to be taught to the dev
word and/or cif-open words?
ATB,
Mark.

QEMU OpenBIOS booting?
by Steven Noonan
Hi folks,
I've been trying to use OpenBIOS with QEMU, and I've had trouble
getting it to boot any PowerPC-based OS discs (Linux, Mac OS X, etc).
OpenBIOS just doesn't seem to find anything bootable. If I try booting
QEMU with -nographic, I get this output (I get the same with a
self-built openbios-qemu.elf from the OpenBIOS SVN as well):
---- snip ----

---- snip ----
Laurent Vivier suggested in this conversation in February
(http://lists.openbios.org/pipermail/openbios/2009-February/003476.html)
that there could be a bug in partition map decoding. Has such a bug
been confirmed? I was trying to find the bug myself (I am an
experienced C/C++ programmer), but the bug seems to be subtle, and my
lack of familiarity with the code base doesn't help much.
I've been trying to figure this out for 7 hours straight now... Any
advice or other help would be much appreciated!

FCode-utils 1.0.2 toke checksum issue
by Asif Haswarey
Hi,
We have run into an issue with our FCodes tokenized using FCode-utils 1.0.2 toke,
on specific SPARC (Enterprise) platforms: M4000, M9000.
Power-up device probe yields the following warning message on the console:
WARNING: /pci@20,600000/...: FCode checksum error; expected: 280d result: 2837
After looking at the OBP sources, I found that the routine:
fcode-sum-ok? : obp/dev/pci/fcode-rom.fth
calculates the checksum by adding every FCode image (excluding header) byte and doing:
lwsplit + lwsplit + h# ffff and
on the sum. The
lwsplit + lwsplit +
apparently breaks the OpenFirmware spec.
OpenFirmware-1275 section 5.2.2.5 describes the checksum algorithm as:
Checksum is the doublet size sum of the bytes of the program body (i.e.,
excluding the header), calculated using two's complement addition and
ignoring overflow.
FCode-utils 1.0.2 toke calculates the checksum in function:
finish_fcodehdr : toke/emit.c
as described in the spec.
How do we deal with this?
Any suggestions?
Thanks for any response(s)!
