BUILT-IN SYMBIOS SCSI BIOS
To provide easy to use and cost effective support for adapters using or compatible with the
Symbios Logic 53C8XX SCSI chips, this mainboard features built-in Symbios SCSI BIOS.
In most cases you should not need to change the default configuration of your host adapter.
You may decide to alter these default values if there is a conflict between device settings, or
if you need to optimize system performance. A message appears on your computer monitor
(for about 5 seconds) during boot that looks like this:
Press Crtl-C to start Configuration Utility
If you decide to press Ctrl-C during boot, the following message appears:
Please wait, invoking Configuration Utility …
After a brief pause, your computer will display the Main Menu of the utility.
The Symbios SCSI Configuration Utility
This menu driven utility allows you to view and change the default configuration settings
for host adapters using Symbios 53C8XX chips.
Note
: Pressing
Ctrl-A

settings and reconfigure.
The following tables list the configuration settings you can change:
