    Re: ACER Veriton Z4660G AIO bios help

    On this machine hdd I found a 13mb file in Acer(D/windows/firmware wich has the same name as the bios. It is a .cap file and dates from before I owned this pc. Could this possibly be helpful. I'm not that knowledgeable but I ran MEanalyser and it stated there was no management engine present.

    Unfortunately it's the only backup I have, I wasn't aware of the flash descriptor lock before I formated the winbond bios chip. I did try to back it up one more time with the ch341a before formating but the file is corrupted and show 0 bytes because It wasn't properly connected or the programmer was sending 5v instead of 3.3v(another issue I wasn't aware at first)...

    Is there possibly a generic bios that could allow me to boot into windows even only once and then update an official acer file from windows?

    Re: ACER Veriton Z4660G AIO bios help

    Yes I have a ch134 programmer, the winbond chip is currently desoldered from the board I'm connecting to it via an adapter not the sop8 alligator clips.

    I already dumped the original bios before formating the chip and flashing new acer website bios.

    But i did so with afuwin from windows and my original dump is missing headers and Intel me and possibly boot code as I was not aware of the existence of those in bios files before a few days ago. And Ok I will do another thread for the schematics, many thanks
