ISC/SCSI all that easy?

Things don't seem to be all that easy with ISC 2.2. I tried ESDI (primary)
Adaptec RLL (secondary) SCSI (for tape only). This is not supported by the
configuration tools and hand patching didn't work for me... :-(

So I took out the RLL: ESDI (primary), SCSI (for tape). --Fails to boot. Seems
like ISC or the driver is waiting for a SCSI disk to come along (works with DOS
and SYTOS, though).

Next try: ESDI (primary, Compaq 150MB (WREN III?)), SCSI (HP xxx (650MB)):
Fails to boot as well. Somebody I know seems to have had the same problem ever
since he upgraded to 2.2. Mixing SCSI and ESDI/MFM/RLL is supposed to have 
worked under 2.0.2.

I would like to see official support for the first configuration (2*AT + SCSI),
because of SCSI tape drives.

PS. Hauppauge acknowledged that the 'driver problem' for the 1542/4860-EISA
combination can be fixed by a new motherboard, also. We got a new motherboard
on monday: it didn't work at all. It's like bying a Ferrari: expect oil on your
fingers every day... We are switching over to BMW's (build in Taiwan), they
actually work! (A486 motherboard by AGC)
