    make backup of chip with eprom programmer then compare tothe .fd in a hexeditor. merge the file then flash.

    u want to cut the platform data out of the .fd

    also some .fd are encrypted ( to find out use phoenix mod tool on the .fd then if it makes filename.fd.dec then it was encrypted)

    thanks for quick reply
    the backup file i took by programmer dosn't match with any of .fd file
    yes the .fd seems encrypted ..by z way the eprom file i took by programmer is 4 MB but the .FD is 2.5MB
    is there is anyway to decrypt the .fd file?
    thanks so much

    the 2mb is replaced within that 4mb file.. not whole 4mb needs update.

    phoenix bios mod tool 2.x should make a bios.fd.DEC if it is

    what is the SP####?
