Nice piece of work! I've been working on an unattended XP installation scheme that hybridizes true unattended installation with the "staged image" style. Basic process is as follows: Boot target machine into PE from boot CD or staging source USB hard disk Run staging batch file:Run diskpart to clean, partition into system and data filesystems, format both Run winnt32.exe /syspart /unattend to stage XP itself Unzip a bunch of drivers onto the system partition Copy the sysprep tools onto the system partition Stage applications onto the data partition [*]Disconnect the staging source USB hard disk (otherwise it gets in the middle of drive letter assignment) [*]Reboot and cross fingers [*]Get coffee and/or start staging the next machine while the staged installation runs I'd prefer to perform the OEM scan during the staging process, replacing the oembios.* files in the staged i386 directory $WIN_NT$.~LS after winnt32.exe finishes. My biggest suggestion, though, is to incorporate your oembios.dat decryption information to automatically look through all available file sets to determine which one(s) apply to the current machine (or a given BIOS dump image) rather than duplicating the information in an .ini file.
