Too bad, the model of Gigabyte socket 939 motherboard only has one Bios chip on board. Which means, you only have the main Bios and no backup bios.

There are two USB connector slots for the chassis or USB PCI bracket usage.

This is the socket 939 of the GA-K8NSNXP-939 motherboard which supports the brand new 8th generation AMD AthlonTM64 / 64FX processor, to deliver a high performance platform with dual support for 32-bit applications and increasing 64-bit computing needs.

As you can see in the rear panel I/O port has PS/2 Keyboard / Mouse, four USB 2.0/1.1 ports, one Gigabit RJ45 ports, two COM ports, one LPT, and Audio (one Line-in / one Line-out / one Mic) connector.

The GIGABYTE GA-K8NS-939 uses the nForceTM3 Ultra chipset.
