    Hy one question,

    one of my friends has a computer with a corporate installation. He dont know a oem installation. He has a HP computer but lost the installation cd. He installed all his necessary programms, so i dont want to reinstall everything.

    I have a ultraboot cd, where i have access to the drive and the registry and can the key and everything.

    IS it possible to replace the oembios files etc... to change the corporate into the oem HP installation ?

    So is it possible what im thinking of replacing the oembios files etc ?

    If your friend has the original key on the system try this. It works very well.

    Steps to create a new XP OEM CD. Handy if you’ve lost the vendor’s original CD, and you want to use the key that’s on the physical PC. Using a retail or MSDN CD won’t help, as your key won’t be accepted.

    1. Copy the full CD contents to your hard drive

    2. Point nLite to your source as per above, and configure to your heart’s content.

    3. Modify the ‘Pid’ number in the file “setupp.ini” to match the key you’re looking to use (note the double ‘P’ in the file name) . It resides in the I386 folder. See below for a list of PID keys.
    I’ve read that the CD Label sometimes needs to match the version of Windows on the disc in order for the installation to work. See below also for a list of CD labels

    4. Burn/Create ISO and install.
    Dell 55274OEM
    Fujitsu 76487OEM
    Compaq/HP 55274OEM
    MSDN 76487000
    MSDN 55274000

    name the cd as follows:

    XP Combo Home/Pro = WXPHFPP_EN

    XP Home Retail = WXHFPP_EN
    XP Home Retail w/ SP1 = XRMHFPP_EN
    XP Home Retail w/ SP1a = X1AHFPP_EN
    XP Home Retail w/ SP2 = VRMHFPP_EN
    XP Home Upgrade = WXHCCP_EN
    XP Home Upgrade W/SP1 = XRMHCCP_EN
    XP Home Upgrade W/SP1a = X1AHCCP_EN
    XP Home Upgrade W/SP2 = VRMHCCP_EN
    XP Home OEM w/ SP1 = XRMHOEM_EN
    XP Home OEM w/ SP1a = X1AHOEM_EN
    XP Home OEM w/ SP2 = VRMHOEM_EN
    XP Home Volume = WXHVOL_EN
    XP Home Volume W/ SP1 = XRMHVOL_EN
    XP Home Volume W/ SP1a = X1AHVOL_EN
    XP Home Volume W/ SP2 = VRMHVOL_EN

    XP Pro Retail = WXPFPP_EN
    XP Pro Retail w/ SP1 = XRMPFPP_EN
    XP Pro Retail w/ SP1a = X1APFPP_EN
    XP Pro Retail w/ SP2 = VRMPFPP_EN
    XP Pro Upgrade = WXPCCP_EN
    XP Pro Upgrade w/ SP1 = XRMPCCP_EN
    XP Pro Upgrade w/ SP1a = X1APCCP_EN
    XP Pro Upgrade w/ SP2 = VRMPCCP_EN
    XP Pro OEM w/ SP1 = XRMPOEM_EN
    XP Pro OEM w/ SP1a = X1APOEM_EN
    XP Pro OEM w/ SP2 = VRMPOEM_EN
    XP Pro Volume = WXPVOL_EN
    XP Pro Volume w/ SP1 = XRMPVOL_EN
    XP Pro Volume w/ SP1a = X1APVOL_EN
    XP Pro Volume w/ SP2 = VRMPVOL_EN
    XP Pro Tablet PC w/SP1 Disc1 = XRMPFPP_EN
    XP Pro Tablet PC w/SP1a Disc1 = X1APFPP_EN
    XP Pro Tablet PC w/SP2 Disc1 = VRMPFPP_EN
    XP Pro MSDN w/ SP1a = X1APFPP_EN
    XP Pro Evaluation = WXPEVL_EN

    Also you can change a XP cd from Retail to VLK or OEM by the following:

    Please note you must own a legal copy with a legit CD Key.......

    WinXP's setupp.ini controls how the cd acts. IE, is it OEM version or retail?
    First, find your setupp.ini file in the i386 directory on your WinXP cd. Open it up, it'll look somthing like this:


    The Pid value is what we're interested in. What's there now looks like standard default. There are special numbers that determine if it's a retail, oem or volume license edition. First, we break down that number into two parts. The first five digits determines how the CD will behave, ie is it a retail cd that lets you clean install or upgrade, or an oem cd that only lets you perform a cleam install?
    The last three digits determine what CD key it will accept. You are able to mix and match these values. For example, you could make a WinXP cd that acted like a retail cd, yet accepted OEM keys.

    Now, for the actual values. Remember the first and last values are interchangable, but usually you'd keep them as a pair:

    Retail = 51882 335
    Volume license = 51883 270
    OEM = 82503 OEM

    So if you wanted a retail CD that took retail keys, the last line of your setupp.ini file would read:


    And if you wanted a retail CD that took OEM keys, you'd use


    Note that this does NOT get rid of WinXP's activation. Changing the Pid to a Volume License will not bypass activation. You must have a valid license key to do so.

    Hope this Helps
