[PPC] Remove "console=" from default kernel command line in yaboot.conf
by Jerone Young 23 Apr '07

23 Apr '07

Currently I have been using IBM JS20 blades running SLOF firmware. The problem that I experience is after an install I have to boot the kernel on disk. In the yaboot.conf, if the kernel command line has "console=ttyS0" on it, I end up getting garbage messages through the serial link when the kernel boots. By booting a rescue image and removing this from the yaboot.conf and letting the kernel autodetect it works fine. 1) Does anyone know why this is here? On x86 you don't specify console= why on power when it can detect it? 2) What situations is this needed for? It may no longer be needed for these situations? 3) What tool adds this exactly (if anyone knows off head, before I look) ? Any thoughts are most appreciated. Should I file a bugzilla ?

Re-creating bootable image from boot.iso
by Robert Allerstorfer 05 Apr '07

Hi, when I burn the 'boot.iso' file found in the 'images' direcory of Fedora 6's ppc DVD-image (FC-6-ppc-DVD.iso) to a CD, I can successfully boot from it with my iBook G4 (ppc-32). I have been trying to re-create a bootable image from it: # mkdir boot; mount -o loop boot.iso boot # rm -rf boot-new; cp -rp boot boot-new # find boot-new -name TRANS.TBL -exec rm -f {} \; # volume_id="PBOOT"; system_id="PPC"; volume_set_id="6"; application_id="Fedora Core 6"; hfs_volume_id=$volume_set_id # mkisofs -V "$volume_id" -sysid "$system_id" -A "$application_id" -volset "$volume_set_id" \ -untranslated-filenames -joliet -rational-rock -translation-table \ -hfs -hfs-bless ppc -prep-boot ppc/chrp/yaboot -chrp-boot -part -hfs-volid "$hfs_volume_id" -no-desktop \ -quiet -o boot-new.iso boot-new Warning: creating filesystem that does not conform to ISO-9660. CHRP boot partition 1 PReP boot partition 2 is "ppc/chrp/yaboot" # ls -l *.iso -rw-r--r-- 1 root root 43642880 Oct 17 20:21 boot.iso -rw-r--r-- 1 root root 43642880 Mar 30 00:35 boot-new.iso As showed above, the new .iso has exactly the same size as the original one. However, when I burn that onto CD and try to boot from it -> no success. What am I missing? thanks, rob. --
