Unattend.txt Parameters (ExtendOEMPartition)

    When using an unattend.txt file to create our Windows 2003 Servers, I have a
    question about parameters within the Unattend.txt answer file. I have no
    problem with the actual set-up of the Server now, however within the actual
    Unattended parameters below, I have set the File system to NTFS and this all
    works fine, but how do you extend the actual partition, for example on the C
    drive I only wish to use 3 BG of the 40GB hard drive, as this will only
    every contain the operation system, all other application will be installed
    on the remaining partition as the D drive.

    I understand from the Microsoft document that, ExtendOemPartition Value are
    set to 0 or 1, ( 0 implies that the partition may not be extended and 1
    indicates that it must be extended ), however how to you set the actual size
    of the partition ?


    I have been looking at the Microsoft Documentation, and have found some very
    useful information, but cannot see how the set the size !

    I have also download the help document,
    (Automating_and_Customizing_Installations and
    Job_Aids_Automating_and_Customizing_Installations) for the Microsoft site,
    but a friend thinks there is an actual downloadable book with all of the
    parameters available, if there is, do you know where I can get this from ?

    Hi Ben-Zion Joselson

    Sorry, but Like I said in my first email message attached, The actual build
    is completed, and have all of the Microsoft Documentation, including
    "Designing Unattended Installations", however although it talk's about the
    unattended build it does not break down each of the parameters, or provided
    different example's. I had been looking form more info on a specific
    parameter (ExtendOEMPartition=1), how do I make this a fixed size, for
    example (ExtendOEMPartition=3072)

    Also the actual link you've provided points to a page that has now been move
    or removed !!!

  4. ExtendOEMPartition=3072 is supposed to work. What happens when you
    try it?

    The document you seek is the Microsoft Windows Preinstallation
    Reference. See http://unattended.sourceforge.net/advanced.html#guide
    for links to the 2000 and XP versions of the document. (The Server
    2003 version is presumably in deploy.cab on the CD, just like XP.)

    I used this same unattend.txt setup file in my last NT4
    to W2K3 Server upgrade. It worked like a champ! The
    parameter ExtendOEMPartition = x where x is equal to the
    actual number in size that you want to extend the
    partition. For example, if your current partition is 4GB
    and you want to make it a 10GB partition, the value of x
    would be 6000 (4GB + 6GB = 10GB).

    Hope this helps.

    Hi Patrick

    Many thanks, I had been using an old hard drive simply for testing the new
    build, the drive size was only 4GB, I had set the ExtendOEMPartition = 3072.
    However I had not taken in to account, that by default the partition was set
    to 2048, and by setting my ExtendOEMPartition to "3072", I was simply
    setting the complete partition to 5 GB. Obviously because of this, I could
    only ever see the drive expanding to 4GB. I have now changed the extension
    to "1024", and on the last test the partition was set to the correct size of

    This was only for testing, as we would not actually be using a 4GB hard
    drive within our live servers ! (just thought I would point this out before
    I get a reply about a size issue).

    Once again thanks for your help in this matter !
