Need help for SOYO 5tt5 mobo

[nick]

hi, I have an old SOYO 5tt5, and want it to support USB port, I checked the bios menu, it only has "usb keyboard" item, and after I upgrade mobo,
it has intel 82371 pci to usb controller and usb root hub, I had try a usb zip, but the port did not work. Do I need to upgrade bios and which version can I uprade to?
Thanks

You might want to try this BETA release (12/97).

If you don't have a USB enable/disable option, then it's permanently enabled.
