@bilemke: i have no experience with PE, but the method you are describing sounds very similar install method i was using before i found out about the OemInfFiles entries. with the $WIN_NT$.~BT folder, ntldr, $LDR$, TXTSETUP.SIF, and minor changes to boot.ini all placed in the root i could boot up the computer for an installation. i believe this method loads the same files as using the floppy-boot install. i just had to throw in my WINNT.SIF into the $WIN_NT$.~BT folder to have a cd-based source. i was hoping to try PE, until i found the method above. is this method similar to your process? i would think making changes to WINNT.SIF is easier than altering $WINNT$.INF. after all, $WINNT$.INF is based off the .SIF file.
