Changing AHA-398x Settings
The AHA-398x has the factory default settings
shown in the following table. These settings are cor-
rect for most computers.
You can change the settings with SCSISelect
®
, the
configuration utility that is built into the AHA-398x.
To do so, follow these steps:
1
If you have not installed the AHA-398x, do so now.
2
Start or reboot your computer.
3
When the SCSISelect message appears, press
Ctrl-A
. The SCSISelect screen appears, listing the
channels. The PCI bus number for the AHA-398x
precedes the channel letter. Channel A on PCI
bus 1, for example, appears as 01:A.

Each channel has its own setting. The default shown is for each channel.
