the error is in the gui mode screens.. but the setup has done nothing when the error apears. i havent used nlite, i never touched txtsetup nor my dosnet files, and yes i tried this on an original xp cd when that didnt work i coppied my winnt.sif,svcpack.inf,$oem$ folder and changed dosnet.inf for the update directory to a corp xp cd and the same happens. i use both slipstream dx9 and wmp9 & mm2 opk packages.. Edit: i found my setuplog this is where the errors begin .. 05/24/2004 09:27:50,d:\xpsp1\base\ntsetup\syssetup\cmdline.c,228,,SETUP: SpSetupLoadParameter was unable to find msdosinitiated. 05/24/2004 09:27:50,d:\xpsp1\base\ntsetup\syssetup\cmdline.c,632,,SETUP: Upgrade=0. 05/24/2004 09:27:50,d:\xpsp1\base\ntsetup\syssetup\cmdline.c,633,,SETUP: Unattended=0. 05/24/2004 09:27:50,d:\xpsp1\base\ntsetup\syssetup\cmdline.c,228,,SETUP: SpSetupLoadParameter was unable to find uniqueness. 05/24/2004 09:27:50,d:\xpsp1\base\ntsetup\syssetup\cmdline.c,228,,SETUP: SpSetupLoadParameter was unable to find AccMagnifier. 05/24/2004 09:27:50,d:\xpsp1\base\ntsetup\syssetup\cmdline.c,228,,SETUP: SpSetupLoadParameter was unable to find AccReader. 05/24/2004 09:27:50,d:\xpsp1\base\ntsetup\syssetup\cmdline.c,228,,SETUP: SpSetupLoadParameter was unable to find AccKeyboard. 05/24/2004 09:27:51,d:\xpsp1\base\ntsetup\syssetup\log.c,133,,Interne gegevensstructuren van Setup zijn beschadigd (fase 0). i hope this helps edit2: it was winnt.sif i forgot MsDosInitiated="0" ..
