    That basically means that you cut the 1B module & run the checksum tool on it.
    If you cut it right then the tool will return success

    If you cut it wrong then it will tell you that the checksum does not match.

    It is trial & error process

    In your case the 1B module is just short of a single FF

    If you add it you will get:

    That works just fine on Windows 8 RP. What are offsets for the 1B module? I am having a hard time locating it in order to replace and use a Dell SLIC.

    start offset: 0x2A98E4
    Attached you find the proper extracted 1B module (not modified)

    Hi Guys,

    Do I need a new 1B module for Server 8, or can I use my 2.1 Dell version from 2008 R2 ?

    Server 2012 you mean? ;)

    You need a new, see above for the RC version, have to test if 1B module is still the same for RTM when it comes available

    Modded vmwp.exe with Dell SLIC 2.1 vmwp 6.1.7601.17514 (for Server 2008 R2 SP1) - work perfectly!

    Link:
    rghost.ru/39545102

    How to install:
    takeown /f C:\Windows\System32\vmwp.exe

    cacls C:\Windows\System32\vmwp.exe /G YOUR-USER-NAME-HERE:F

    don't forget to replace YOUR-USER-NAME-HERE with the user u want to give permission to

    Replace vmwp.exe from system32 folder with the downloaded one after renaming it...

    Would the vmwp.exe from Windows 8 Enterprise N RTM be the same as the one included in the Server 2012 RTM Editions?

    Anyway, for the 1B module for Windows 8 Enterprise N use these offsets:
    Code:
    start: 0x2AB8F4
    end: 0x2DFADB
    length: 0x341E8
    Attached you find Windows 8 Enterprise N RTM vmwp.exe 1B module with FSC SLP and SLIC

    At a guess I'd say no, as Windows 8 appears to have a cut down version of Hyper-V v3.
    But theres no reason for the 1B module being different 'cos its doing the same job.

    I better get a move on and start trying to make my Dell version.

    Wrong :D

    I can confirm that vmwp.exe taken from Windows Server 2012 RTM is exactly the same as the one from Windows 8 RTM

    hashes:
    Code:
    CRC32: 12EB5540
    MD5: 7928D8D0FFAB676BEFE3D9D6EDC15F12
    SHA-1: 37A442FAA49803F884235975E753221AC4720928
    below you find (unpatched) 1B module

    Nothing unusual about me being wrong. :D

    Don't you mean Server 2012 not Server 2008 ;)
