Hello
Wish to know
Was the Mxic 25u1001e you programmed a new chip ?
If not, did programmer auto-detect it or you wrote it's ID manually ? and did you backup bios file without error (i.e read old content)?

Yes, programmer auto detect it. And I backup bios file without error, but problem in rewriting it. This motherboard's original chip

I would try another bios chip 128kb 1.8v and see if programming succeeded. I happen to see bios chips read successively but failing to be reprogrammed.
