I recently purchased a secondary Adaptec 1540B (no floppy) controller for my
386/25MHz machine to attach an Archive Viper 150S to for backups.

After installing all of the hardware into this already running machine, I
rebuilt the kernel after configuring the HPDD under kconfig, option 8. Now,
when I boot the machine, it gives "Booting the UNIX system...." and hangs.

I originally thought it might have been the way the card was set up, but I
verified that it was at the standard defaults by the manual, as well as
examining /etc/conf/kconfig.d/space.dsk.gen and 
/etc/conf/kconfig.d/space.tape.gen. 

My system configuration is: (after stripping out any unnecessary components..)

	AMI 80386/25MHz no cache, or FPU
	8mb Memory
	Adaptec ESDI Floppy/Hard Controller
	Western Digitial Paradise VGA Card
	Two 338mb CDC ESDI drives setup as type 47 (User defined type) with
		1222 cyls, 15hds, 36 sec/trk
	and of course,
	an Adaptec 1540B SCSI controller with an archive viper 150s attached
		internally at ID 6.

Trying the obvious with the SCSI tape drive, i.e. setting the ID at 0,3, or 6,
and trying it external showed no effect.

From a previous posting to this group, I think I remember reading that you
cannot leave the BIOS disabled for the SCSI card to work (JP6, jumper 1), so
this jumper is in place. 

In addition, when booting, after the machine's diagnostic as installed both
C and D drives to the internal HDs, the Adaptec banner screen comes up with
C: and D: already installed, not installing SCSI BIOS or something similar.

Does this all mean that you can have a SCSI controller as a secondary controller
but only if you have but one standard AT drive installed?

Any help or comments would be greatly appreciated.....
