I also have two sets of five beeps on boot with modded T510, but it boots and works just fine. I guess the embedded controller does some kind of hash calculation on BIOS and warns about BIOS corruption. Serg008, when modding for WL, how do you find an entry point in the EFI file? Btw, is it using any x86_64 opcodes, or is it plain x86?
I'm looking for someone with a correctly modified BIOS for the Lenovo 3000 N200 (type 0769). The links to the modified BIOS that I find are all dead. Maybe someone has it and can repost? Thanks!
