The post on those HP forums was stating that he had the 6.09 version which someone responded there was an updated version from May 2013. But like I said the link was dead.
Here's an SS of CPU-Z of my mobo.

The entire specs are as follows:
AMD Phenom II X4 955 3.2GHz
Foxconn 2A92 BiOS version is American Megatrends Inc 6.09
EDITED: The HP site actually states the mobo is Foxconn H-RS780-uATX so I'm confused.
6 GB (3 x 2 GB) DDR3 PC3-10600
1 TB, 7200 rpm, SATA 3G (3.0 Gb/sec)
GeForce GT420 (2 GB)
Win7 Ultimate(64bit) SP-1
Here's a link to the HP spec list:
HPE500z
The HP driver download section doesn't have a BiOS update but I've read that there was one or two more updated drivers released for it. Just can't seem to find them.
