SLP Keys are special CD Keys which are issued to Royalty OEM Manufactures. These CD Keys are REQUIRED for activation using the OEMBIOS Method. SLP CD Key’s ARE NOT COA Sticker keys on the side of the computer.
SLP CD Keys won’t activate unless you have a Royalty OEM Motherboard & OEMBIOS file set that match the motherboard.
SLP keys aren’t locked to the oembios files. You can use a dell slp key on a gateway system. You MUST use a Pro SLP key with a XP Pro installation and a Home SLP key with a XP Home installation. Some discussion was raised that Microsoft in the future could match the manufactures issued slp keys to the system however some manufactures use other manufactures keys so I think its unlikely. Some people have written scripts to go along with OEMSCAN which change the cd key for each oembios set. I don’t know anything about them, so don’t ask. Giving out SLP CD Keys appears to be against forum rules so don’t ask.
Oembios file sets aren’t dependent on the version of XP your installing. The same file set will work on Pro or Home. Royalty OEM’s inject a string into the bios, the OEMBIOS.DAT file tells Windows the string and string location in the bios. No you can’t mix and match different OEMBIOS parts, all four files must be from the same set. The OEMBIOS.DAT file is encrypted, “some” people have tools which can decrypt the file this is how they know the SLP strings. Don’t ask for the tools you won’t get them. OEMBIOS File sets are identified by the CRC32 hash of the oembios.cat file. Rapid share is deleting unpopular files from Bazalel’s repository. You can copy the 4 oembios files (oembios.bin, .cat, .sig, .dat) from a factory installed copy of XP to get that OEM's FileSet if you can't find it.
To add a set to oemscan, acer for example.
Create a directory in the same directory oemscan.exe resides and name it Acer. Download 717B6EF3.RAR from Bazalel’s repository and extract its contents to the Acer directory. Open oemscan.ini in notepad and add the following.
'AcerSystem ,AcerSystem ' is a comma separated list of SLP Strings that Windows activation checks. Two instances of AcerSystem means there are two memory addresses that Windows XP Checks. Refer to http://www.msfn.org/...mp;#entry534097
for a list of SLP strings and CRC’s. No you don't have to create Multiple entries for AcerSystem, just one for each unique name.
You can run OEMSCAN.EXE any time during setup, be it from cmdlines.txt, svcpack.inf, or RunOnceEx. You can even run it after XP has installed. Auto Accept Royalty Keys? I use winnt.sif and have one static SLP key for Pro & Home.
