    usualy u make a backup.bin from broken and extract bios from download then compare and trim it in hex editor then flash works.

    seems the bios is the .com file
    heres the command it uses to flash both bios and EC (embedded controler)
    not sure how this one would be done but i think its special.

    chgbiosf.exe bio007dt.com,ec77v150.bin /f /R

    usually to reset pwd there is a contact point under tape by memory slots. under it. looks like a copper T with a U under the T.
    or sometimes is J1 . 2 silver dots with a white line in between them.
    sometimes its xxx

    my best guess is u read it wrong. always read bios with different sector size 4k or 32 or 64k. (backup4k.bin backup32k.bin backup64k.bin)

    what programmer u have ? (hope its not some home made unreliable)
    i have EN25T80 cheapo from ebay with a programmer soft i found in russian satellite forum.
    i tried the home made programmers and 1/2 the times it had read write error (verified by comparison)

    if u do have a home made.. do 3 reads and compare them all to eachother.. if none match. go back to drawing board of programmer schematics.
    or buy a premade one.

    :confused: As I know, you are looking for it at least two years and without no avail. Whether you are suddenly looking for the wind on empty field?
