Bios Mods -The Best BIOS Update and Modification Source

hello,

what is the latest bios version of this motherboard m2n68-LA narra6 6.00A?
i would love if someone can provide me with a bios update.i am not having any result from searching in hp support website.the pc model is p6231fr.
My current bios is AMI 5.04,5/8/2009 , AMD AGESA v3.5.1.0.[attachment=18594]

check this post - maybe search for the sp52418 package, which has Narra6 bios version 6.14 with AGESA 3.7.1.0

edit 7/6 - apparently the sp52418 & sp52419 packages that have the Narra6 v6.14 bios only work with "2A99" motherboards which are "revised' Narra6 boards with either HP part nos. 612501-001 or 612502-001 that have less than the 6.14 bios version. they may not work on some Narra6 boards that don't identify themselves as "2A99" (the sp52418 & sp52419 bios update files won't update bios with Narra6 boards with part no. 537558-001) and don't work on few other Narra6 boards that have newer bios than 6.14.

open up the hp computer case with a phillips-head screwdriver and look at the small "stickers" on the m2n68-LA narra6 board, which should mention the HP PN number (ex. 612501-001).
