Ok, just thought I'd share this. I have a non-Dell laptop running XP Home that only came with a recovery CD but which I wanted to nlite'n using a valid Key for my laptop. I have access to a Dell OEM XP Home sp1 CD via the company I work for. To create an nlite ISO ... I copied the Dell cd to my HD and removed the following: \$OEM| \DOTNETFX\ \I386\SVCPACK\ \WIN51IC.SP1 \I386\WINNT.SIF \I386\UNNATEND.TXT \I386\SVCPACK.DL_ \I386\SVCPACK.INF \I386\XPSP1RES.DL_ \I386\Q*.EXE I then edited the following and changed the .1106 to .0 to change to non-sp1 \I386\DOSNET.INF I then used nlite to slipstream SP2 to the modified source I then copied the following from either the INF or SYSTEM32 directories of my currently installed XP Home sp2 system to \I386 in the modified source: SVCPACK.INF SVCPACK.DLL SVCPACK.PNF I then used nlite to tweak, unnatend, etc... then create ISO So far it has installed and run fine from within VMWARE The above should be correct although there were numerous faltering steps during the process so I could always have forgotton something.
