In most cases your computer, host adapter, and SCSI
peripherals are now ready to use.
Configuring the Host Adapter
Your host adapter includes the built-in, menu-driven
SCSISelect configuration utility. SCSISelect lets you
change host adapter settings such as interrupt chan-
nel and host adapter termination without opening
your computer or setting switches. SCSISelect also
includes a low-level formatting utility.
Running SCSISelect
There are two ways to invoke SCSISelect:
■ Press Ctrl-A when prompted at boot time.
■ At the DOS prompt type debug and press Enter.
Then at the
Debug prompt (a hyphen), type
g=
xxxx :6
where
xxxx = first 4 digits of host adapter BIOS
address in hex. (D8000h is the default address.)
Use the arrow (↑↓) and Enter keys to make selec-
tions in SCSISelect. Press Esc at any time to return to
the previous menu. You can press F6 to restore the
original default settings. To abandon changes you
made in the Configure/View Host Adapter Settings
menu, press Esc and select No when asked if you
want to save the changes.
Main Menu Options
Configure/View Host Adapter Settings
The Configuration screen displays the basic software
configurable options: IRQ, Host Adapter SCSI ID,
Parity Checking, and Host Adapter Termination.
Highlight an option and press Enter to see a list of
possible values. Some options include information to
help you determine which value to select.
If you select SCSI Device Configuration you can
view another menu and change these options for
each device on the SCSI bus: Initiate Synchronous
Negotiation, Maximum Synchronous Transfer Rate,
Enable Disconnect, Send Start Unit Command, and
Include in BIOS Scan.
