    Hello,

    Could someone tell me if this is correct:

    1) retail cd to oem cd

    If you have a retail cd you only need to replace these files on the cd:
    DPCDLL.DL_
    OEMBIOS.BI_
    OEMBIOS.CA_
    OEMBIOS.DA_
    OEMBIOS.SI_
    PIDGEN.DLL

    Edit setupp.ini and add oem.

    When ask for a key during install, enter the right SLP oem key.

    There is no need to add the $OEM$ folder or WINNT.SIF or SETUPREG.HIV?

    The retail cd also has these folders:
    WIN9XMIG
    WIN9XUPG
    WINNTUPG
    Is it necessary to delete them or can they stay?


    2) retail installed to oem installed

    If you have a retailed version installed, you need to decompress this Manufacturer oembios files:
    OEMBIOS.BI_
    OEMBIOS.CA_
    OEMBIOS.DA_
    OEMBIOS.SI_
    and replace the old files on your harddrive with the decompressed ones.

    Then you change the key to the right SLP oem key.

    And you are done.

    For a Retail cd you only need to copy over the four SLP OEMBIOS files that
    match the SLP string in the bios:

    OEMBIOS.BI_
    OEMBIOS.CA_
    OEMBIOS.DA_
    OEMBIOS.SI_



    Then, change the last 3 digits of the PID Value inside SETUPP.INI to OEM


    To convert a VLK (Corporate) CD to OEM PRO you do the same as above,
    but you need to copy some extra files, listed below, from a Retail Pro CD and replace them as well:

    DPCDLL.DL_
    EULA.TXT
    NT5INF.CA_
    PIDGEN.DLL
    SETUPREG.HIV



    See Sticky thread for info and SP3 files needed:

    Thanks!

    Can these folders stay or do they have to be deleted.
    WIN9XMIG
    WIN9XUPG
    WINNTUPG

    Well, firstly let me tell you what the above mentioned folders are for:

    • WIN9XMIG includes files required to migrate from Windows 98
    • WIN9XUPG includes files required to upgrade from Windows 98
    • WINNTUPG includes files required to upgrade from Windows 2000

    Also, if you plan to install the Recovery Console to HDD (which adds an option on Boot) you must have WINNTUPG.

    Therefore, considering we all tend to do clean installations for Windows XP, these days, it is pretty safe to delete the above folders, especially in unattended installations where we can utilize that saved space for other Application Setups.

    Basically, delete them if you're falling low on space, i.e. if your ISO image exceeds 700 MB.

    What is the difference of upgrading vs migrating when installing windows?

    Is this the correct why to change an installed retail to an installed oem?
    Or is it a lot more difficult.

    I read the "OEMBIOS changer" could do this automatic.
    Any danger with this tool?

    migrating is the IT term for using a tool to save your settings and files (most of the time the USMT), then formatting your system laying down a new OS and then copying your files and settings back.

    Hey guys if I take my OEMBIOS files from my existing OEM install, can I just put them into my retail ISO and then change the setup.ini? or do I need to compress them first? If so, how do I compress them?

    Those five extra files that are needed for the VLK to OEM cd - are they language independent? I've read in some other threads that they may not be, and just want to make sure that the files that you link to in the sticky will also work with my Danish VLK. Thanks.

    Some say yes and some say no..I think if any will be it is the DCPDLL.DLL file.

    You can always just change the oembios files after install. If you use SP3, you dont even have to enter a serial to install. install then change the oembios files. you can make a simple changer for those..I will make the script if you want..

    Which OEM?


    You can also use the OEMBIOS changer if you take a copy of the dcpdll.dll and pidgen.dll and put them in the language folder. It will then install all the correct files..

    If you want to convert a MCE VLK XP to a MCE OEM XP, then do also have to change this files DPCDLL.DL_, EULA.TXT, NT5INF.CA_, PIDGEN.DLL, SETUPREG.HIV?

    If so can I use the files from a winxp pro retail?

    Is there a way to check if a key work with a certain xp cd without installing it?

    You need to know the CRC32 of the OEMBIOS.CAT in the set. Then match it up to the set SLP..XP should be the same. The serial number tells the install to look to the components folder for MCE..

    If you use an XP serial, you get XP install. If you use MCE serial, you get MCE...

    Thanks, I replaced the 4 bios files with those of HP. The SLP is also HP.
    I just wasn't certain if I could use DPCDLL.DL_, EULA.TXT, NT5INF.CA_, PIDGEN.DLL, SETUPREG.HIV form xp pro retail.

    Ya, the PRO and MCE disks are the same inside the I386. The only difference is the added MCE components folder and MCE key.
