	installation disk.

Description
-----------
AcerPower 466de PC user will encounter the above-mentioned problems when 
attempting to install the Easy SCSI disk.  The reason is the AcerPower 466de 
PC has a built-in SCSI interface chip that clashes with the IRQ and I/O address 
of the SCSI interface on the SB16 SCSI-2.  Both interfaces are set to the default 
of IRQ 11 and I/O address 340 Hex.

Solution/Action
---------------
This problem can be solved by either changing the IRQ and I/O address of the 
onboard SCSI controller through the PC's CMOS setup or changing the IRQ and 
I/O address of the SB16 SCSI-2 to other addresses.  User are to refer to their 
respective manuals to change these settings.

After making the above changes, update the config.sys file as follows:

	DEVICE=C:\SCSI\ASPI2DOS.SYS /P:340 /Q11 /Z /P:140 /Q:9 /Z /D

	On board SCSI interface setting: /P:340 /Q:11 /Z
	I/O Add	:	340 Hex
	IRQ	:	11
		
	SB16 SCSI-2 interface setting: /P:140 /Q:9 /Z
	I/O Add	:	140 Hex
	IRQ	:	9
