    The module is correct

    Code:
    Current checksum value is f8556b8b
    Checksum header value is correct. No update needed.
    
    but I am sure Dell System is not in correct place

    @kingwilliam

    Yep !
    sebus is right : you put string Dell System at the wrong place !
    It does not work every time to put any OEM string next to BIOS Date. :p
    (does not work with either Sony Corporation, nor MSI-PC for example...)

    To make it work, (one of the 3) string(s) Dell System *MUST* be placed at memory 000FE076, length max 16 decimal (000FE086)
    Problem with Hyper-V 1B module : there's no fully empty space here (not filled with 00 only) !
    Might work to overwrite these not null bytes, but it'd be safer to find another space (so better use another OEM string) ;)

    An advice i can give you : use Dell Inc or Dell Computer strings as you can put them in null filled space :
    000FE840 for Dell Computer (the one i used myself :D)
    or 000FE838 for Dell Inc (this is 8 bytes before Dell Computer string)

    In the 1B/2012 module case, please write string Dell Computer at position 123CC, and xp's oembios files will be happy :biggrin:

    Dear Jacoub
    Stop Hyper-V service
    Close any instance of server manager program or Hyper-V console
    replace vmwp.exe with modded one
    Good Luck

    1. download slic2_1b_20120912.rar
    2. extract slic2_1b_20120912.rar, you will get slic2.2_1b file
    3. use any hex editor open vmwp.exe
    4. use slic2.2_1b replace vmwp.exe at location 0x2ab8f4 - 0x2dfada
    5. save vmwp.exe to new file.
    <DONE>

    I thought there was a different vmwp file that came with SP1.

    Depends on the question, was the question about slic 2.2 or exe?

    I am sure Manolo would have 08 R2 SP1 on 03 Dec 2012, 19:21
