I was unable to reach you via EMAIL so I am posting the solution to the
net.  There are actually two ways to fix the problem.
The original 1000 used interrupt 5 for the video (same as the PCjr it
was made to compete with), but regular PC's use int 2.  The SL and all
other current 1000's now use int 5 for the HD.  The hard drive
is probably set to use int 2, so it needs to be switched to 5.
If the drive is a hard card you need to change the jumper on the long
vertical row on the right edge of the controller from 8 to 7 (or is it 7
to 8?, I'm at school so I don't have docs handy, so just reverse the
position of said jumper.)  Then change the jumper on the short
horizontal row on the lower right from 2-3 to 1-2 (same reversal rule
applies.)  This should fix the problem.
If the drive is a seperate drive/controller set do this:  The controlelr
has a jumper marked with the interrupt settings, change it, dealt with.
If you need more help you can call me or post another followup, I'll be
happy to give a hand.  Good luck!
