(Symbios Utility)
Configuring Your Host Adapter
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.
To perform the configuration described in this chapter you must have SDMS BIOS
version 4.xx.xx or higher, and it must include the Symbios Logic SCSI Configura-
tion utility. You can see the version number of your SDMS BIOS in a banner dis-
played on you computer monitor during bootup. If the utility is available, a message
appears on your computer monitor (for about 5 seconds) during bootup that looks
like this:
Press Ctrl-C to start Configuration Utility
The Symbios Logic SCSI Configuration Utility
The menu driven Symbios Logic SCSI Configuration Utility allows you to view and
change the default configuration settings for your host adapter.
NOTE: This utility is a powerful tool. If, while using it, you somehow disable
all your controllers or cannot enter the configuration utility, pressing “Ctrl-A”
after memory count during reboot allows you to recover and reconfigure.
The following tables list the configuration settings you can change. The global
settings affect your host adapter and all SCSI devices which are connected to it. The
device settings affect only individual SCSI devices.
