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):

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!

Currently we only support the Sparc64 CPU types emulated by QEMU, not
real hardware. The CPUs types are:

Some of these are not fully emulated by QEMU or supported by OpenBIOS (IV*, T*).

Since the second type does nothing, this could also be written as
?dup if
type space
else
drop
then
It's at most a cosmetical difference though

PATCH: Don't add padding spaces when evaluating headerless words
by Mark Cave-Ayland
Hi everyone,
When executing "words" in order to see the word list for a current
package, if any headerless words have been created during Fcode
evaluation then even though they have no name field, the padding space
is still added. This causes excessive space padding between headered
word entries with headerless words between them within the dictionary.
ATB,
Mark.
