I'm working on an old PIII 450 Gateway w/ Win98se. It keeps losing it's wireless nic driver (WMP11). If I do a cold boot it launches the new hardware wizard. It says it found "PCI Card" and even if I point to the driver it still won't load it. Then I reboot and it works. Reboot all day, works fine. Cold boot it's gone till reboot. I have loaded the newest driver from Linksys. There is no newer bios available from Gateway. I tried different PCI slots. I ran Windows Update. I thought it may be the battery, but the time and date stay correct. I don't know what else to try.

Any thoughts?
