Try to find Bios rom and reflash the bios back with programmer

DUDBOY 写了：Try to find Bios rom and reflash the bios back with programmer

Agree, with programmer the bios rom must be the same size of your BIOS chip, such as 4M or 8M or 16M.
That is meaning you cannot use the rom file downloaded from HP.com, which is usually 3.xM in size or whatever.

Then bios tool need to be called to initialize the computer information(S/N, P/N, etc.)

Kindly try this ROM file enclosed but AT YOUR OWN RISK, this rom should also be applicable on 8470w, even has a chance on 8570p.

Additionally i share a rom file of 6470b.
6470b has very similar motherboard desgin with 8470p, but it has dedicated bios rom which has the ME fuction limitted.
This file may be even applicable on 6570b because the rom update program of these computer modules is the same file on HP.com .

Save your old bios after flashing
