These files enable to boot WinXP Pro SP1 from a USB hard drive. They were created following instructions in http://www.ngine.de/index.jsp?pageid=4176 and tested on Windows XP Professional SP1. You need to add these 6 files to your i386 directory replacing 5 old versions there. You may use nLite if you need to re-create a disc image (iso). Includes cabarc.exe, used to pack the modified files in MSCF/Cab format.
