that does not already have a device assigned to it is avail-

able for use.

All Windows operating systems: When PCI bus IRQ steering

is enabled, Windows will direct PCI bus IRQs to devices

such as your modem. Sometimes, however, the IRQ that

Windows assigns to your modem will conflict with the com-

puter’s BIOS.

To disable IRQ steering: Select Control Panel >System > Device

Manager >System Devices. Right-click PCI Bus, then click Properties

to open the Properties page. Click the Resource tab, then IRQ Steer-

ing. Disable IRQ Steering. If the PCI modem you have just in-

stalled is listed, highlight it and click Remove, and then reboot

your system. If this doesn’t disable the “IRQ Holder for PCI

Steering,” please contact Microsoft Technical Support.

IRQ assignment: Only computers with an updated BIOS will be

able to assign an available IRQ to the PCI slot on the mother-

board. Check your computer’s documentation, or the mother-

board itself, for the number of the PCI slot.

If you have a VIA chip-based motherboard: Computers with

this chipset frequently have problems installing PCI modems

unless the VIA IRQ Routing Miniport Driver is installed. If your com-

puter’s User Manual doesn’t specify that your motherboard is

VIA chip-based, you can examine the motherboard to check. If

you do have a VIA chip-based motherboard, refer to

http://www.via.com.tw/en/support/tech_faq.jsp for driver in-

formation and help.

Problem

Your modem seems to install but Windows cannot find it later.

Solution

If your computer has a built-in modem on the motherboard, Win-

dows may reinstall it the next time you start up. Consult your

computer’s documentation or call your computer’s manufacturer

to get instructions on how to disable the built-in modem.

Problem

The software cannot find the modem and the modem does not

respond to AT commands. (The following comment applies to

many other problems as well.)
