So, using the "Award BIOS IDs" link on the homepage, that works out as:
2A59G - Intel Triton VX chipset (Socket 7 based m/b)
G3 -
Gemlightwhich suggests you try
Hongfaith where it says you have to register - but go to
the BIOS page and search for 2A59GG39 to look at the files they list first.
BTW, moderators, the hongfaith link needs updating.
