I made a slipstreamed SP2 cd with winnt.sif under i386, created a $oem$ folder and put my cmdlines.txt, regtweaks.reg, useraccounts.cmd and autologon.reg files in there. Installed XP and it obviously reads the winnt.sif just fine, but it totally seems to have ignored my cmdlines.txt because it hasnt executed my accounts stuff and hasnt done any of my registry tweaks. I also have a $1 folder inside $oem$ and inside this I have a drivers\NIC folder containing my ethernet driver inf files. i have pointed oempnpdriverspath to that folder as you can see in my attached sif, and it also ignores this. I must have done something wrong any ideas? my cmdlines.txt is: [COMMANDS] "useraccounts.cmd" "REGEDIT /S regtweaks.reg" and its obviously not touched it at all (or it has and it failed for some reason). I've attached my winnt.sif and renamed it to .txt for easier reading. Thanks WINNTSIF.txt
