: My BIOS is a 1996 version v4.51PG 12/20/96 SIS5571-2A5IHM49C-00 It doesn't have USB enable in it. I have not been able succesfully find an update. Can anyone help. Kevin


Probably hopeless for onboard USB function. Your mainboard must have the hardware connection (pin header) and the feature must be supported by the chipset - otherwise you'll need a USB expansion card.

Study your manual - if USB is not mentioned and the USB header is not identified on the mainboard layout - then you don't have the feature.

If you don't have a manual, download one from the mainboard maker's web site. You will need to know your mainboard maker and mainboard model - maybe even mainboard version. If you need to figure out what you have just follow the motherboard ID article at:

If you DO have the USB function BE VERY CAREFUL. I have identified at least ten (10) DIFFERENT pinouts for the USB header and at least as many connector combinations. If you connect the wrong connector on your USB header you will burn out your USB function before you get started and may damage the mainboard and power supply as well. BE VERY CAREFUL. USB may be plug and play on the outside but it definitely IS NOT plug and play inside the case.

I think you'd be safer and happier with a USB card.

Good Luck,
Henry
