PCI Controller problem with new motherboard
WAPGeek Jun-22-00 03:57 PM
Hi,
I just replaced my motherboard. When I turn on the system almost everything works..except.. Win98 does not recognize my modem card... and I get an "Unknown device" dialog box which asks to load drivers.. It doesn't find the drivers on the mb's cd or the Win98 CD. Is this referring to the modem? Any help would be greatly appreciated. I am considering formatting and doing a clean install.

Thank you.

The unknown device may or may not be the MODEM. The problem is probably being caused by an IRQ conflict and a clean install will more than likely not resolve it. Many MODEMs are set for COM2:, IRQ 3. Try going into the motherboard CMOS Setup and disabling the CMO2: port on the motherboard. If that doesn't work, go into the Control Panel, System, Device Manger and look for exclamation marks on drivers and see if there is an IRQ conflict. If there are try forcing the offending device into using another IRQ in its Properties, Resources (msany boards cannot be forced). Use Start>Help>Windows Troubleshooters for more steps. You may need to use IRQ sharing in a loaded computer. Enable OS is PnP aware in the CMOS Setup. Another thing that often works is to delete all of the COM ports in the Device Manager and the MODEM and rebooting. If you reinstall the MODEM you will have to go into the Properties of Dial-up for you ISP (My Computer, Dial-up networking) and tell it to use the most recently installed MODEM. Larry
