Bios Mods -The Best BIOS Update and Modification Source

This an oldie out of an E-Machines EL1358G (which they had subsequently relabeled as their own) The board is no-longer found on any Acer website and countless google searches only led me to one source. The bios has only one official repository remaining as well, even though it is not listed on Acer's site it is still there at least

I had recently purchased an AMD Phenom II X4 Black and to my dismay i couldn't even access the CPU multiplier or any voltage settings (as if i want to mes with those yet). Still any help in unlocking this BIOS would be greatly appreciated.

I have the emachines el1358g-51w and it is on the bios version p01-b3 and I cannot find the revised p01-b4 version anywhere. Can anyone link me a copy of that revised bios for this pc? Any help is appreciated...I suppose i should say that i cannot boot into windows on this pc either but can boot up a recovery enviornment.

I have been looking for this bios update to no avail, thank you for the download. I don't know much about modifying a bios though.
