I've run into a new and unexpected problem while attempting to boot.
After selecting "Boot Now", the booter proceeds quite normally until right
when the mac side would vanish and be replaced by bsd.  At this point, the
screen freezes.

I've looked though all the options and preferences, and they were
unchanged from the last time I had a successful boot.  I've tried with the
mac extensions on and off.  I've tried booter versions 1.9.4 and 1.9.7 and
gone so far as to trash the copies I had been using and replace them with
new copies. 

I should add that this is a Performa 550, with the booter on the internal
HD and netbsd on a zip disk.

I also note that, when I give up and force-restart, the mac starts up
right away (unlike a typical crash & restart, in which there is the long
delay before the "welcome to macintosh" screen), which suggests that the
mac-shutdown procedures enacted by the booter are completed before the
freeze. 

Is this likely to be a problem on the mac side, or the bsd side?  If mac,
then what?  If bsd, how can I fix it if I can't boot the system?

Please help.  This has really got me down (so to speak)


Thanks,
