QEMU OpenBIOS booting?
by Steven Noonan May 24, 2010

May 24, 2010

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 ---- >> ============================================================= >> OpenBIOS 1.0 [Apr 12 2009 00:55] >> Configuration device id QEMU version 1 machine id 1 >> CPUs: 1 >> Memory: 128M >> UUID: 00000000-0000-0000-0000-000000000000 >> CPU type PowerPC,970FX Welcome to OpenBIOS v1.0 built on Apr 12 2009 00:55 >> ELF - yaboot_startup: Entering boot, no path >> ELF - try_bootinfo: Trying hd:0,ppc\bootinfo.txt >> ELF - try_bootinfo: Can't open hd:0,ppc\bootinfo.txt >> ELF - try_path: Trying hd:2,\ofclient >> ELF - try_path: Can't open hd:2,\ofclient >> ELF - try_path: Trying hd:2,\yaboot conf=hd:2,\yaboot.conf >> ELF - try_path: Can't open hd:2,\yaboot >> *** Boot failure! No secondary bootloader specified *** ---- 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! - Steven

PATCH: Don't add padding spaces when evaluating headerless words
by Mark Cave-Ayland June 6, 2009

June 6, 2009

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.
