■ The SCSI IDs on one SCSI channel do not interfere
with the IDs on another SCSI channel.
■ If you have two host adapters connected to the
same SCSI bus, be sure to assign them different
SCSI IDs, preferably IDs 7 and 6.
Completing the Installation
1 Put the chassis cover back on the computer, fol-
lowing the directions in the documentation.
2 Be sure all power switches are OFF, then reconnect
power cables to your computer.
3 Turn ON the power for the computer and the
peripheral device(s).
4 If your system CMOS
Setup
requires you to
enable PCI bus parameters, do so now. Refer to
your computer documentation.
Note: The PCI bus is supposed to automati-
cally assign Interrupt channels (IRQs) and
port addresses. But because PCI is currently
combined with other bus architectures such
as ISA and EISA, you may need to edit the
PCI bus parameters in your CMOS
Setup
.
When the computer boots, the host adapter BIOS
sign-on message appears on the screen. This mes-
sage includes a list of installed SCSI devices and
information about the BIOS. In most cases your com-
puter, host adapter, and SCSI devices are ready to
use, and you do not need to run SCSISelect.
Configuring the Host Adapter
Your AHA-3940/3940W host adapter includes the
built-in SCSISelect configuration utility. SCSISelect
lets you change host adapter settings, such as parity
checking and host adapter SCSI ID, without open-
ing your computer or flipping switches.
To run SCSISelect, press Ctrl-A immediately when
the SCSISelect message appears on the screen at the
time your computer boots.
