Hello from Germany! I successfully created a bootable XP SP3 USB-Stick with all updates/patches until june 2013 It is a DELL CD, containing the SLP key and the four OEM-bios-files. Now I want to make this USB stick useable for all vendors. So now Im looking for the following function during XP setup process, I will write it in my own words, not "tech-language..;-)" 1) when XP setup is running, detect the OEM BIOS String (using the oembios.exe or any other function 2) use the result to detect the correct four OEM BIOS Files, extract the files and copy the files to the correct folder 3) "inject" the correct SLP key to the winnt.sif file 4) finish XP setup... Any1 around to have this job done before? Thx and best regards! Peter
