I have almost the exact same symptoms. What I did was to attempt to play
with the printer cable with the power on (a REAL no-no) and blew out my
parallel port. I can boot off of kickstart 1.1 but not 1.2. Apparently
1.2 has more rigourous machine tests. (I think) My solution has been
to leave my future sound plugged into the port. For some reason this
seems to patch the problem (i've been meaning to fix it, I understand
the chips that handle the printer port are socketed, or at least thats
what I'm told).
