Help!!! IWILL KA266 & Modem install problem

[alchemize]

Having some troubles installing a 3Com/USR internal 56K modem. Everytime I drop the card into the board, when Windows98SE reboots, it detects a "PCI Serial Controller". I can't find a driver for this, it won't take the modem driver. Any thoughts? There is a SB Live and a Geforce 2GTS on the board as well.
