Thanks -- but sometimes the brave get burned :-)

The problem exists at the BIOS level -- not the OS level.  It appears
that the BIOS is trying to auto-detect the disk info (model number,
heads, cylinders, etc), and this task fails, so it hangs.  Maybe I
sent an abnormally high jolt (large voltage) through the actuator and
it really made a weird magnetic pulse on the platter??  Destroying all
the drive info?  Where is that data stored???  On the platters or on
the electronics?

I got OpenBSD too to try, and I have a laptop->IDE converter -- could
give it a shot...

Hah!  A valuable learning experience is rarely monetarily valuable :-P
