hi i think the solution is to remove the reference to the usbehci.sys file! i know, that's not the ultimate solution, and i also don't exactly know how to do it, but maybe somebody can help me work it out?? here is what i found out: the reference file for the text-based installation of windows is called txtsetup.sif and is located in the i386 folder i have scanned through the file before adding sp 2 (i also don't have sp1) and there is no reference to the usbehci file, but after adding sp 2 there are some entrys for this file... i just don't know what to remove exactly, maybe somebody with more knowledge about the syntax etc can help??
