NOTE:  TO ANYONE INSTALLING A XYLOGICS 753 WHILE RETAINING THEIR 451 CONTROLLER

Xylogics had a MAJOR BUG in their firmware!!!  I was experiencing THE SAME
EXACT error message as Dave did.  The solution is to RETURN your board to
the company you purchased it from and have them send you the LATEST REV
level from Xylogics (date 27-Mar-1989 (?)).  

After installing the new board, I am running:
	4/280 32M memory
	SCSI tape
	Xylogics 451 with 1 Hitachi DK815-10
	Xylogics 753 with 2 Fujitsu M2372K

with no problems (knock on wood . . .).
