Thx (another one ) Whats the real use for the encrypt command as the files are not digitally signed, so validation will always fail, isn't?
After writing decrypt it was trivial to add encrypt, so i made them both. The real use of it? Don't know, maybe to store files unencrypted in archives for better compressibility. Or in case someone will find private key for public one stored in winlogon.exe. I wonder is oembios.bin just dumb set of 100 random data blocks or is it something encrypted? So far i saw no usage of it other than comparing md5 of its blocks to ones stored in oembios.dat.
I do not know the answer you are looking for, i think you are right and it are just random data blocks used to compare against the ones in oembios.dat
OEMBIOS Editor Been filling in time by practicing my DOS batch files. if you were thinking of creating a few slipstreamed OEM pre-activated Windows XP Professional CD's and have stumbled across the decryptoembios.7z posted by tnpuser then this is for you. Loved the fact that you could tell which Manufacturer's OEMBIOS files were on your CD so I automated it you can download this from my windowstipsclub.blogspot Just follow the instructions on the WINRAR self exe files then run the editoembios.exe in the created root drive folder oembios, within 20 seconds you will be given the MSDOS editor window with the contents of the OEMBIOS.DAT file from your source CD, this wil also work if you have mounted ISO images as it will find the file regardless.

Latest version of my OEMBIOSEDITOR2.exe Had a problem with the pervious link to I have upped the latest version OEMBIOSEDITOR2.exe to rapidshare the password on my windowstipsclub.blogspot, sorry I can post links on the forum as I only have 3 posts need 17 more to post hyperlinks SpideRaY
Link is now working again !!! Sorry I had a few problems with RSM2 updating cause a few problems I have now uploaded the latest version OEMBIOSEDITOR2.exe for all your users. SpideRaY
Urie, Just added my OEMBIOSVERIFY2.exe tool works in a similar fashion to the OEMBIOSEDITOR2.exe uses the same root folder, this one automates the checking of your source OEMBIOS files. As soon as I get the ability to post links to Rapidshare on this forum I will do until them they are on my windowstipsclub.blogspot search for OEMBIOS and it will bring up this post for the tools and the other two relating to Slipstreaming OEM install CD for Windows XP Professional, also added one of my first batch files that will check pre-activated OEM systems by re-registering the DLL's if there is a problem with them. Keep up the good work love the site and the fast response to comments SpideRaY
Hi All, @ tmpuser : thanks sir, but where are you now ? we are missing you ! Sir/Madam(s), the easiest way i am able to use tmpuser's utilty is as below : 1) extract 'decryptoembios.7z' to get 'decryptoembios.exe' with archivers like 7zip, WinRAR,etc. (mine : 7zip) (i suppose you have already installed one of them) 2) then place decryptoembios.exe & OEMBIOS.DAT in the same folder. for eg. i would place both files in a temporary folder in c: root i.e. 'c:\NewFolder1\' (i suppose you have already downloaded and extracted 'XP oembios set' relevant to your system manufacturer and model ) 3) type 'cmd.exe' in the 'start menu search box' and press 'Enter' (administrator rights are not required). it will bring up a command prompt window. Now navigate into the temporary folder 'c:\NewFolder1' from within command prompt using 'cd' command. then run the 'decryptoembios.exe' with 'dx' command for xp (d3 for 2003 key) from the same location to decrypt OEMBIOS.DAT and propose a name for the output file. For eg. c:\Users\LittlePro> cd c:\NewFolder1 c:\NewFolder1>decryptoembios dx OEMBIOS.DAT xyz.txt and press 'Enter' c:\NewFolder1>exit after exit from command windows , i simply navigate to 'c:\NewFolder1' and double click 'xyz.txt' and compare the values ! NOTE: 1. I don't think, encrypting back and to work with, will make any sense as tmpuser says himself ! 2. avoid leaving spaces in the name of files ,folders, ISOs, etc. which you have to work with. because it was unfunctional sometimes ! 3. ignore/omit quotes ' ' , '' '',etc.as they are used to make the things clearer and not to confuse/complicate ! ) Thanks & Regards, LittlePro
