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: : get-file ( 6000 ffe35870 27 ) 00000000ffe36378: fname>devname$ 3 > 2dup type /platform/OpenBiosTeam,OpenBIOS/ufsboot ok 3 > resume ok ( 6000 ffe35870 27 ) 00000000ffe36378: fname>devname$ ( 6000 ffe35ee8 2f ) 00000000ffe36380: ufs-fopen 3 > 2dup type cdrom:a,|platform|OpenBiosTeam,OpenBIOS|ufsboot ok 3 > resume ok ( 6000 ffe35ee8 2f ) 00000000ffe36380: ufs-fopen : ufs-fopen ( 6000 ffe35ee8 2f ) 00000000ffe360e8: drop ( 6000 ffe35ee8 ) 00000000ffe360f0: cif-open ( 6000 0 ) 00000000ffe360f8: (semis) : get-file ( 6000 ffe35870 17 ) 00000000ffe36378: fname>devname$ 3 > 2dup type /platform/sun4u/ufsboot ok 3 > resume ok ( 6000 ffe35870 17 ) 00000000ffe36378: fname>devname$ ( 6000 ffe35ee8 1f ) 00000000ffe36380: ufs-fopen 3 > 2dup type cdrom:a,|platform|sun4u|ufsboot ok 3 > resume ok ( 6000 ffe35ee8 1f ) 00000000ffe36380: ufs-fopen : ufs-fopen ( 6000 ffe35ee8 1f ) 00000000ffe360e8: drop ( 6000 ffe35ee8 ) 00000000ffe360f0: cif-open OFMEM: ofmem_claim_virt virt=ffffffffffffffff size=0000000000000200 align=0000000000000001 ( 6000 0 ) 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?

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 ---- >> ============================================================= >> 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

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)! -Asif
