I have created an unattended XP Disk with just the winnt.sif file and sata drivers on the cd, no software and no OEM setup. If i use the disk with the sata drivers on the setup goes fine but on first login it crashed and just goes into a continuous reboot cycle, in safe mode the last file loaded in mup.sys. If i remove the sata drivers from the disk and load them from floppy, but leave everything else the same it work fine. Anyone got any ideas what could be causing this? (txtsetup.sif and winnt.sif attached) Thanks Jamie Sif.zip
