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 Aug. 25, 2010

Aug. 25, 2010

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 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

FCode-utils 1.0.2 toke checksum issue
by Asif Haswarey Jan. 28, 2010

Jan. 28, 2010

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
