This is the first time I'm trying an unattended XP install. All I'm adding are my raid drivers by following this tutorial: http://maximumpc.com/2005/01/how_to_slipstre.html When I install, I get the following error: "The file sisraid.sys could not be found", and the install is aborted. here's my WINNT.SIF: My sisraid.sys file is sitting in the cd driectory "\$OEM$\$1\drivers\RAID\winxp" so I don't know why it wouldn't be able to find the file. The tutorial I followed also had me mess around with a TXTSETUP.SIF file to add some info about my driver to it (like "PCI\VEN_1039&DEV_0180&REV_01 = sisraid"). Do I even need a modified TXTSETUP.SIF file to do this? Why can't it find my file?
