Chapter 4 Hardware Setup
38
WA133 Series
In the PCI bus design, the BIOS automatically assigns an IRQ to a PCI
slot that has a card in it. To check the IRQ map of your system in
Windows 98, the Control Panel icon in My Computer contains a System
icon, which gives you a Device Manager tab. Double click on a specific
hardware device gives you the Resource tab, which shows the IRQ and
address. Make sure that no two devices use the same IRQ or your
computer will experience problems. If your expansion card must be
performed with a specific IRQ, you can enter BIOS setup program to
assign the specific IRQ in PnP/PCI Configuration page.
4.6 Usage of the AMR slot
This motherboard provides a Audio Modem Riser (AMR) slot to support a specially designed audio and/
or modem card called an AMR card. Main audio and/or modem processing is done by system processor
to provide an upgradeable audio and/or modem solution at an incredibly low cost.
There are two type of AMR card, one defined as primary and another defined as secondary. This
motherboard uses the primary channel so that a secondary AMR card can coexist without the
need to disable the onboard audio CODEC. The onboard audio CODEC must be disabled when
using a primary AMR card.
4.7 Connect Devices and Power Supply
All the connectors showed in this section are not jumpers, DO NOT
PLACE JUMPER CAPS OVER THE PINS OF THEM. If you do so, you
will damage the motherboard permanently.
