    Hi all, I did a silly thing in UEFI shell and erased All NVRAM variables, don't ask me why...
    Now only black screen, no post...:(

    Have searched but can't find info on Bios Recovery, have disassembled to clear cos, but still same.

    Appears to access dvd only, usb not working so need crisis cd and also what key to press if any.

    Am waiting on a soc8 test clip so will try spi flash when it arrives.

    If anybody can help would be much appreciated..

    My aim is to Hackintosh it of course...

    Thanks

    Sorry for late reply.
    These bioses are all different sizes 2.1MB 3.1MB 8.4MB(P03.A1L) WTF...Crap Acer documentation as well.
    Looks like its going to be the SPI route...
    Board has rom_recovery header so need to make cable to do spi flash.
    Thanks for your help.
