Adaptec 1542 / Exabyte under ISC -- how ?

[Gregory Benjamin]

What I have:
AST 386/20 with 200MB 3.5" Conner IDE disk, VGA, Adaptec AHA-1542b as
secondary controller, Specialix SI/8 intelligent serial card, WD 8003E
Ethernet, and ISC Unix 2.2.1.

Configuration:
Ethernet and serial card are presently out of the system, but the drivers
are still in the kernel. The Adaptec is set to factory defaults, with 
floppy disabled and BIOS ROM enabled. Kconfig for HPDD has AT as primary, 
Adaptec as secondary controller, Exabyte tape.

Symptoms:
Boots under DOS via floppy *very* slowly. Passes DMA diagnostic. Recognizes
Exabyte as Target 4, LUN 0 when diagnostic is run. ISC won't boot when 
Adaptec card is in the system, but does if it is removed.

What I'd like to know:
What target number should the tape be set to, or doesn't it matter? Where can
I find documentation on this? What else, if anything, do I need to do to get
this combination working?
