Hi there,
I just bought used HP ProDesk 400 G6, BIOS locked, tried to reset password with CMOS clear which didn't work. I also tried to find rom for this PC cause I have CH351A, but there is only useless '.exe'. So I was curios if I can use any other rom from here edited by hoaca388? Thank you!

I tried using CH341a and SOC-16 clip on chip itself(GD25B256DFIG) but as some guys before NeoProgrammer shows "IC not responding: as well. I am a noob in this area of computing and don't really understand how some other users actually succeded in reading rom from this IC. I really need your help guys. Thank you very much!

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..
here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow
