Installation in the Computer
Perform the following steps to install the QLA22xx board in your PC:
1. Check the motherboard and make any configuration changes necessary to
accommodate the QLA22xx board.
The QLA22xx board is self-configuring; however, some motherboards
require manual configuration. For example, some systems have a PCI
Device Configuration menu in the motherboard setup BIOS where you must
enable host adapter boards, bus master slots, and interrupt request (IRQ)
levels. If the motherboard supports triggering, use level triggering for the
QLA22xx board. See the documentation supplied with your computer, or
contact your computer dealer to determine if your motherboard requires
configuration.
2. Power down the peripherals, then the computer.
3. Remove the computer cover and save the screws.
