I borrowed an Adaptec 1542B to use in my machine for a while to see
how things would go.  Sadly, they don't go very well.  

I made a backup and then reformatted the disk using as suggested in
the manual.  Restored from backup, and everything was just fine.
Everything would work just as it used to.  Except when I pound on the
disk reading and writing files.  Then, BOOM---internal processing error.

It seems that under heavy disk activity, the whole system is flakey.
It causes some program to halt with access violations.  When the disk
activity stops, and I rerun the exact same program, everything goes
just fine.  Other times the whole thing stops with an internal
processing error.  Usually trap e at the same location.

Some specifics:

	AHA1542B, default settings, except 5MB/sec DMA.  Termination
		resistors removed.
	Mylex 386 motherboard
	Conner internal harddrive, SCSI ID 0, terminated.
	Archive tape drive, SCSI ID 4, external, terminated.

	Beta aha154x.add from Adaptec BBS.  12/92 version

The SP aha154x.add was really flakey.  The beta version was MUCH
better---at least I can get some stuff done if I'm careful to
single-task everything :-(.

Does anyone have any suggestions and/or comments?  Since the 1542 is
such a popular controller, I have to believe it MUST work better than
this.  I'm doing something stupid I hope.

Thanks for your help!
