Technical Support Note
======================
Reference TSN No. : NA
Product(s) involve : SB16 SCSI-2
Third party product(s) : Acer - AcerPower 466de PC
Subject
-------
1. Unable to install CDROM driver using SB16 Easy SCSI CDROM
installation disk.
2. Unable to detect CDROM using SB16 Easy SCSI CDROM installation
disk.
3. System hang during/after installation of SB16 Easy SCSI CDROM.
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
