You added a Promise Ultra100 PCI card, right?
So if you moved the HP tape drive to the PDC, move it back to
the mainboard's IDE controller.
Also, don't disable the mainboard's controller thinking you can save
some interrupts that way. Andre Hedrick (Linux IDE guy) once wrote
that this could cause the PDC to grab IRQ 14, which had some nasty
side-effects.
(My main box runs with disks on a Promise Ultra100 card and
ATAPI CD-RW and tape on the mainboard's IDE (440BX) controller.
Both 2.2+ide and 2.4 work fine.)
