Device Manager on my system only shows

SiS 7001 PCI to USB Open Host Controller
SiS 7001 PCI to USB Open Host Controller
USB Root Hub
USB Root Hub

which matches the two USB ports on the rear of the K7S5A MOBO. Both
Ports seem to accept a USB peripheral device just fine.

That means the machine is not recognizing the front USB ports at all.
I had already looked at the BIOS hoping to see some way to activate
the headers, but don't see anything.

Thanks again
