Installed new Abit KU8 AMD64 3700 1G Mem but WP Pro sp2 no longer sees or\nwill install my external USR 5686e modem on Com1 serial port. Latest bios\nand mb drivers. Abit and USR support worthless. Tried a new Diamond USB\nmodem and it installed but won't connect.\nInternal PCI modems work but slower than what the USR external was on old P3\nsystem. Tried many bios settings to no avail. No conflicts shown in\nControl Panel or SiSoft Sandra Pro.
