Restoring yaboot

[Andrew Birch]

A few things I've found that differ from the How-To on YDl's site.

When re-running ybin:

Boot from the Cd and at the prompt type "linux root=3D/dev/hdaxxx" {enter}
instead of "cd-linux root=3D/dev/hdaxxx"

>From this point the boot loader will pickup the boot processes off the
hardrive and you'll be in.

Then from a root console, run /usr/sbin/ybin , to reset yaboot.

I found this works great, but the boot from OPTION key to select OS never
works for me, and the Reset Firmware option doesn=B9t seem to work anymore,
either.
