You need to update your disk bootstrap.  Do this (as root, under linux):
 
1. Get the latest quik release (cap.anu.edu.au).
2. install the quik rpm (rpm --rebuild quik.*.rpm)
(old:3. cd to the quik directory and type "make install".)
4. type "quik -vf".

addon: you can also talk to your OF and boot back into an old kernel that you 
might have left behind. just type (at the 'boot:' prompt) vmlinux.old (or any name that you have 
called the kernel).  you'll need to do it before the boot prog tries to boot.  the time is set by 
default to 1 sec but you may change that in /etc/quik.conf.  another way to save yourself is by 
pressing comand-option-p-r and zap the pram.  this should get you back into macos and from there 
use boot variables.

A kernel downloaded (or uncompressed) in ASCII form and not binary will also
result in a default catch error during boot-up.  Make sure it's binary.
