Installation in the Computer
Perform the following steps to install the QLA23xx board in your PC:
1. Check the motherboard and make any configuration changes necessary to
accommodate the QLA23xx board.
The QLA23xx 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 IRQ levels. If the
motherboard supports triggering, use level triggering for the QLA23xx
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.
4. Choose any PCI bus slot that supports bus mastering. Most motherboards
automatically assign an IRQ level and interrupt line; if your motherboard
does not, you must assign the IRQ level and use interrupt line A for this slot.
NOTE:
■ Some motherboards have two kinds of PCI bus slots: master
and slave. The QLA23xx board must be in a PCI bus master
slot. (Some motherboards have PCI bus master slots that are
shared with onboard devices. QLA23xx boards do not work in
shared slots.)
