My Inspiron 2500 just went through a series of problems, and after wrestling with it for a few days, I've almost got it working. The only remaining problem is that the modem doesn't work. It is installed, and says its working, but MSN can't find it. The only problem I see in the device manager is that a system device 'Microsoft System Management BIOS Driver' has a question mark. I don't know if it will fix the problem, but its a start. Does anyone know where I can find that driver?
