    Hi folks,


    That I know (very few), please check if no mistake:
    ===================================================


    About Award-Phoenix bios...
    use a great tool cbrom download at rebelshavenforum.com/CBROM.html

    A) how the number of modules and the functionality of each module ?
    cbrom.exe biosFileName.bin /D

    B) how remove a module (eg: epa logo, pci,...)?
    cbrom.exe biosFileName.bin /moduleName release


    About Dell bios...
    C) how to get a bios file from dell?
    Download it Dell: ftp.dell.com/bios

    D) how to get hdr file from exe file:
    biosFileName.exe -writehdrfile

    E) how to get bin file from exe file:
    biosFileName.exe -kromfile

    F) How to modify a module into hdr file:
    used winhex like soft x-ways.net/winhex/index-f.html


    That I would like to know (lot of stuff):
    =========================================

    About hdr file for dell latitude e6400...
    1) How to know the number of modules?
    2) How to identify the functionality of each module?
    3) How to find the beginning and the end of each module?
    4) Where to write CRC into hdr file after modification, at the end of each module?
    5) How to flash the bios with hdr modified?
    6) How to recover dell bios e6400?
    partial answer...
    rename *.hdr file, but which one (i did find the name in *.exe, *.hdr neither *.bin files)?
    Copy *.hdr on USB Key or Floppy,
    Unplug AC adapter and battery from the bricked laptop,
    Plug USB-Floppy with hdr file stored on it,
    Holding press "END" on the keyboard,
    Plug AC Adapter,
    when the battery light is on with red,
    Release "END",
    The power light is on,
    Laptop power up,
    Keep waiting,
    Finally, the lapop shutdown or restart!

    7) What are the differences between hdr file and bin file (provided by dell exe file)?

    (Sorry for English mistake I'm not fluent)

    Need to read more about Dell bios decompose.
    Don't know if still available for E6400
    But:
    -biosFileName.exe -writehdrfile
    Code:
    extract hdr file (ROM file with header,krom file and checksums)
    -biosFileName.exe -kromfile extract only krom file,
    Code:
    keyboard controller,also know as KBC or EC ,this is the firmware for main controller of notebook.it deals with keyboard,hardware controll.is something like SUPER-IO in PC's but with more functions included.

    I would wondering if one of authors or readers of this thread could summarize these 70 pages by answering to my questions (briefly) :)
