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