III. INST ALLATION Expansion Cards III. INSTALLATION 4. Expansion Cards WARNING! Unplug your power supply when adding or removing expansion cards or other system components. Failure to do so may cause severe damage to both your motherboard and expansion cards. Expansion Card Installation Procedure 1. Read the documentation for your expansion card and make any necessary hardware or software settings for your expansion card, such as jumpers. 2. Remove your computer system's cover and the bracket plate on the slot you intend to use. Keep the bracket for possible future use. 3. Carefully align the card's connectors and press firmly. 4. Secure the card on the slot with the screw you removed above. 5. Replace the computer system's cover. 6. Set up the BIOS if necessary (such as IRQ xx Used By ISA: Yes in PNP AND PCI SETUP) 7. Install the necessary software drivers for your expansion card. Assigning IRQs for Expansion Cards Some expansion cards need to use an IRQ to operate. Generally, an IRQ must be exclusively assigned to one use. In a standard design, there are 16 IRQs available but most of them are already in use, leaving 6 IRQs free for expansion cards. If your motherboard has PCI audio onboard, an extra IRQ will be used, leaving 5 IRQs free. If your motherboard has ISA audio onboard, an extra 3 IRQs will be used, leaving 3 IRQs free. Both ISA and PCI expansion cards may require the use IRQs. System IRQs are available to cards installed in the ISA expansion bus first, then any remaining IRQs are available to PCI cards. Currently, there are two types of ISA cards. The original ISA expansion card design, now referred to as legacy ISA cards, requires that you configure the card's jumpers manually and then install it in an available slot on the ISA bus. To see a map of your used and free IRQs in Windows 98, the Control Panel icon in My Computer, contains a System icon, which gives you a Device Manager tab. Double-clicking on a specific hardware device gives you the Resources tab which shows the Interrupt number and address. Make sure that no two devices use the same IRQ or your computer will experience problems when those two devices are in use at the same time. 24 ASUS P2B-D/P2B-DS User's Manual

Expansion Card Installation Procedure
1.
Read the documentation for your expansion card and make any necessary
hardware or software settings for your expansion card, such as jumpers.
2.
Remove your computer system’s cover and the bracket plate on the slot you
intend to use. Keep the bracket for possible future use.
3.
Carefully align the card’s connectors and press firmly.
4.
Secure the card on the slot with the screw you removed above.
5.
Replace the computer system’s cover.
6.
Set up the BIOS if necessary
(such as
IRQ xx Used By ISA: Yes
in PNP AND PCI SETUP)
7.

Assigning IRQs for Expansion Cards
Some expansion cards need to use an IRQ to operate. Generally, an IRQ must be
exclusively assigned to one use. In a standard design, there are 16 IRQs available
but most of them are already in use, leaving 6 IRQs free for expansion cards. If your
motherboard has
PCI
audio onboard, an extra IRQ will be used, leaving 5 IRQs
free. If your motherboard has
ISA
audio onboard, an extra 3 IRQs will be used,
leaving 3 IRQs free.
Both ISA and PCI expansion cards may require the use IRQs. System IRQs are
available to cards installed in the ISA expansion bus first, then any remaining IRQs
are available to PCI cards. Currently, there are two types of ISA cards. The original
ISA expansion card design, now referred to as legacy ISA cards, requires that you
configure the card’s jumpers manually and then install it in an available slot on the
ISA bus. To see a map of your used and free IRQs in Windows 98, the

tab. Double-clicking on a specific hardware device gives you the Re-
sources tab which shows the Interrupt number and address. Make sure that no two
devices use the same IRQ or your computer will experience problems when those
two devices are in use at the same time.
