yaboot problem...can't boot gentoo...Dual USB iBook

[whosgothecrack]

i have fully installed gentoo linux 1.2 for the PPC. i am having trouble booting...when i restart my computer i don't get any decision about which os to install...i have macosx and gentoo linux on the same hard drive. my hard drive print out from mac-fdisk looks like this:

/dev/hda1 Partition Map
/dev/hda2 Driver 4.3
/dev/hda3 Driver 4.3
/dev/hda4 NewWorld Block (bootstrap)
/dev/hda5 Unknown
/dev/hda6 Unknown
/dev/hda7 Unknown
/dev/hda8 Unknown
/dev/hda9 Unknown
/dev/hda10 HFS
/dev/hda11 HFS
/dev/hda12 Linux native (boot)
/dev/hda13 Linux swap
/dev/hda14 Linux native (root)
/dev/hda15 Free space


my yaboot.conf has these values:

boot=/dev/hda4
device=hd:
partition=14

root=/dev/hda14
delay=10
defaultos=macosx
timeout=40
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot

image=/boot/vmlinux
label=Linux
read-only

macosx=/dev/hda10
enablecdboot
enableofboot


any ideas on why i'm not booting? and how do i get back into my edit my yaboot.conf from booting the cd? thanks for your help.
