I have a Sun SLC (8 meg memory) with a Boxhill 424MB 3.5" disk attached 
(as well as a Boxhill 8mm and 150MB 1/4" Cartridge Tape Drive).  The Sun 
104 Meg disk that came with the workstation has crapped out so we 
purchased the Boxhill 424 disk.  I loaded SunOS 4.1.2 on this disk and 
other than the constant rebooting problem it works fine.  Has anyone else
had this or a similar problem?  Below is an exerpt from the
/var/adm/messages file, the only clue I could find to what may be
happening, however, I'm not sure where to start looking for the
actual problem, i.e. connectors, cables, h/w, s/w, bad block on the
disk...?  I thought this would be great, I finally got that wretched 3/50 
off my desk and now this SLC is turning out to be worse than the
3/50!  The problem seems to exist regardless of whether I have the
8mm and 1/4" drive connected.

HELP!!!
