that's good - you've proven that you don't need the PAM8 ROM -

Make sure you have the jumpers on the drive configured correctly - the
H17 controller works "backwards" - you need to setup SYS0: as DS3; SYS2:
is configured as DS1; HS should be strapped and MX must be open - check
out the drive strapping illustrations in the H17 manual. I'm using a
Tandon drive (with the IBM logo) with a hard sector controller in my H89
which is set up the same way - your "old" IBM drives may not be old
enough!

If I can stop breaking my H8 long enough to copy a boot disk for you,
I'll be glad to provide one, but if somebody else can help out, please
chime in!
