This looks exactly like a problem I ran into due to user error. BootX
predefines the path to /dev. you must include /sdb5, NOT /dev/sdb5 in the
BootX text box.

Do you get any scsi timeout/reset error messages during boot? Linux likes
to renumber scsi busses alphabetically, rather than what traditional unix
does, e.g. Adaptec comes before Mesh,...so check to see that /dev/sdb points
to the correct bus & device.

Except for some of the newer machines, stick with kernel ver 2.2.6 that
comes with YDL CS 1.1 It is stable. Latest version of BootX is 1.2fc1 This
is compatible with the mac OS9 device drivers.

See http://ppclinux.apple.com/~benh/ for the latest BootX, and yaboot 0.5,
an alternative which uses Open firmware. For older hardware, BootX is your
only option.
