■
If you are booting from the AHA-2944UW and you
also have an ISA/EISA-based host adapter installed,
you must disable the BIOS on the ISA/EISA-based
host adapter.
■
If you are booting from an ISA/EISA-based host
adapter and you also have an AHA-2944UW
installed with a boot device connected, the ISA/
EISA-based host adapter will boot before the
AHA-2944UW.
■
When running the SCSISelect utility, if the utility finds
multiple AHA-2944UW host adapters in your com-
puter, it displays the PCI bus number and PCI device
number of each host adapter. To determine which of
the host adapters SCSISelect is configuring, view the
red LEDs on the host adapters as you move the high-
light bar to different host adapters with the
↑
and
↓
keys. (The computer cover must be removed to view
the LEDs.)
Installing Device
Drivers
Some operating systems have an embedded driver for the
AHA-2940UW. These drivers work fine with your
AHA-2944UW; however, the most recent version of the
driver should be installed in order for your AHA-2944UW
to perform at its optimum level.
If you purchased your AHA-2944UW in a kit, the kit
includes the latest Adaptec EZ-SCSI
®
and Adaptec 7800
Family Manager Set software.
■
Adaptec EZ-SCSI
—allows you to install software
drivers for DOS/Windows
®
and several additional
utilities. Refer to the EZ-SCSI Quick Reference.
■
Adaptec 7800 Family Manager Set
—allows you to
install software drivers for NetWare, OS/2, Win-
dows
®
95, Windows NT, and UNIX. Refer to the 7800
Family Manager Set User’s Guide.
You can order EZ-SCSI or the 7800 Family Manager Set
by calling the number listed on page 11.

Troubleshooting Tips
If you have a problem during installation, check these
items first:
■
Have you installed the host adapter in a PCI Rev 2.0
compliant computer?
■
Are all SCSI devices powered?
■
Are all SCSI bus cables and power cables properly
connected? Is pin 1 oriented correctly?
■
Does the host adapter and all devices on the SCSI bus
have unique SCSI IDs?
■
Is pin-1 orientation maintained throughout the SCSI
bus? (See Connecting Internal SCSI Devices on page 3.)
■
Are all devices on the SCSI bus terminated
properly?
■
Does your system CMOS setup require you to enable
PCI bus parameters? If so, see your computer’s docu-
mentation. Check that IRQ channel assignment,
board, and BIOS settings have been made.
■
Did you install your host adapter in a bus master PCI
slot? Refer to your computer’s documentation or try
another slot.
■
Is parity checking consistently enabled or disabled on
all devices on the SCSI bus?
Computer Will Not Boot from a SCSI Disk
Drive
If both SCSI and non-SCSI disk drives are installed, then
the non-SCSI disk drive is always the boot device. If the
system has only SCSI disk drives, do the following:
1
Make sure the drive type in your computer’s CMOS
setup is set to No Drives Installed.
2
Make sure the boot hard disk SCSI ID corresponds to
the Boot Target ID setting in SCSISelect. The SCSI ID
is normally set with jumpers or switches on the drive.
3
If this does not solve the problem, back up all data on
the SCSI hard disk and perform a low-level format
with the SCSISelect Format Disk
option. See the
MS-DOS documentation for instructions on partition-
ing the disk after formatting.
