If you have Bios Version FA (which is really old, BTW) on that MB then it is a Rev 2.x MB. The Rev 2.x MB's use F followed by a Letter for the Naming Scheme. The Rev 1.x MB's use F followed by a Number for the Naming Scheme. But as stated above it is always best to Physically look on the MB to be sure.
thanks guys it was a fa.. rev 2. i have just updated it to f k..rev 2 now for a bios mod......hopefully
