    they take at least a day to reply, if they even do.

    u could get a usb spi programmer and try to recover chip by making a backup.bin then we merge bios with a hexeditor and flash fixed.bin to see if it works.

    or u can try a bios chip from ebay, much easier.. if it works (%10 chance it might not be right bios in chip but they tend to fix the issue with second chip)

    need DMI tool for that board like NBDMIFIT 1.19

    all the info is under battery .. except GUID which is a randomized number/letter

    or maybe hotswap bios (to change chip while in dos ready to swap and flash) and flash old ?
