Uhh, no. This will reset the PRAM, and not help yaboot at all
since it
relies on the boot-device setting in the PRAM to work.
Hmm. Methinks that's *precisely* what one can choose to do (i.e reset
PRAM). Usually (always?... this is how I've done it always) the yaboot
partition is the first bootable partition on a drive which means that
a PRAM reset will (and *does*, I can tell you from first hand
experience) restore yaboot as the default boot device (since the PRAM
reset resets the boot device to the first logical (?) partition).
The way to get yaboot working again is to boot up holding down
the option
key. This will boot into a boot device selector. Wait for the spinny
cursor to stop, and it should show you the bootable partitions.
Usually
one for OS X and another for linux (complete with the Penguin).
Boot into
Linux and as root run ybin to set boot-device to the yaboot boot
partition. Everything should be well again.
Yes, this is an alternate solution (takes a little longer than
command-option-P-R ;-).
cmd+option+P+R won't always get you to yaboot, it really depends on
_your_ disk is setup and particular OF version honestly. Using the
method with option is a much better way of doing it as it's not a
crap shoot. Even if yaboot is your first bootable drive it doesn't
equate that each open firmware version is going to find it first. By
default OF looks for :txbi to boot, and not :yaboot
So again to sum it up holding option at boot ensure you can boot
properly into linux, and rerunning ybin is the better option without
a doubt (no guess work, the computer then knows exactly what to boot
again and it doesn't have to search for a bootable partition on each
startup).
