Hello everyone, I have an HP 840r G4 whose BIOS I reprogrammed, and when I turn it on, it takes a long time to boot up. This is not normal. Can you help me find the correct file? I've attached the original BIOS file.

Re: HP BIOS unlock tool

Hey guys, is there a trick to getting good data out of the W25Q256JV bios chip on an Elitebook 840r G4 in circuit? I must have read it half a dozen times each with random bits flipped. Once I manage to reliably read the data I guess I'll post it for RethoricalCheese to modify unless there is something I can do myself?
