I am having the same problem as mBird. I am trying to install Promise Fasttrack 378 as I can avoid inserting a floppy at the boot up, However I get a message like " missing file fasttx2k.sys". altough I have compressed the driver and it is in the i386 and the PRO1. I have cofigured dosnet.inf, txtsetup.inf and winnt.sif as it is been directed, there is no problem with that. I am very sure because I succesfully installed unattended WinXP using a CD but when I intgrate that installation in to AIO-DVD I get the error message. So something must be wrong with the PRO1, I am please help me.
