TECH TIP NO. 15.001

DATE:	         May 10, 1991
BOARD TYPE:      FAST DISK EISA SCSI HOST ADAPTER
BOARD REVISION:  Series 15 Rev D or D1
BOARD FREQUENCY:
RELEASED BY:     Engineering Dept.


PROBLEM:   The Floppy Disk Controller on the Series 15 Board is not compatible 
	   with a streaming tape drive.

REASON:    The Intel 82077-1 Floppy Disk Controller used on the FAST DISK EISA 
	   SCSI HOST ADAPTER does not support the streaming tape drives.

SOLUTION:  Intel now has a version of the Floppy Disk Controller that is 
	   compatible with streaming tape drives.  The Intel part number is 
	   82077AA-1.  All boards should be shipped with the new 82077AA-1 
	   Floppy Disk Controller in the future.  If a customer has a board
           with the 82077-1 Floppy Disk Controller and needs to use a 
	   streaming tape drive, the Floppy Disk Controller should be swapped 
	   for the new one.  It is a 68-pin PLCC package at U76.  It is in a 
	   socket but a special tool is needed to remove it from the socket.
