I'm not sure I did! The mobo had 2 USB ports only usable via headers, but they never worked, no matter what device I plugged in them. I don't know what was in my head when I first bought this mobo, even the PS/2 port was available to use via a header too. It was always very hard to connect devices to it. Anyway, yesterday I threw the mobo as I've tried almost everything I could, took the battery out, clearing CMOS, reading on the internet about PCI USB card and I learned that if I connected a USB keyboard to such a card, I woudn't be able to access the BIOS menu at boot time. But, "the mobo is dead, long live the mobo!". I also have a boxed, never-used k7vt4a pro mobo for socket A(462). I'll try to find a sempron proc as I don't have one yet. The pc I write this from is also a piece of antiquity: 11 year old Mendocino 520 MHz/ Intel440BX.
