Hi bezabel Sorry for my bad english and for my newbie question, but I am confused. I had Samsung notebook with XP HOME. I had copy files created by CollectFiles.rar and the files from activation.rar to the $oem$ folder of the CD. I deleted OEMBIOS.BI_ OEMBIOS.DA_, OEMBIOS.SI_ from the CD and I removed all lines referencing any of the OEMBIOS files (including OEMBIOS.CAT) from txtsetup.sif and dosnet.inf. I had rebuild XP HOME CD. After install this to other pc still give me to activate. What is wrong? The contents of my $OEM$ directory is: 53616D73756E6720456C656374726F6E696373.BIN 53616D73756E6720456C656374726F6E696373.CAT 53616D73756E6720456C656374726F6E696373.DAT 53616D73756E6720456C656374726F6E696373.SIG cmdlines.txt CreateBatFile.vbs RestoreOEMFiles.bat RestoreOEMFiles.tmp smbios2.exe
