Hi, I got an problem with my bios (F.58 A hp dv6871us): http://forums.mydigitallife.net/posts/21326789 and a search about the beep codes, but i found some weird information about it, for example, that sites: http://www.phoenix.com/NR/rdonlyres/81E6C43C-93BD-4097-A9C4-62F05AAD6025/0/biospostcode.pdf http://pcsupport.about.com/od/fixtheproblem/tp/phoenix-beep-codes.htm says that 1 long and 2 short beeps are checksum error, and others says that are video. In the official site they say anything. Is it becouse of the version? (my new one is F.58 A) Can someone help me? Thanks for all.
