I am trying to install Windows XP pro SP3 on my Panasonic CF-U1, using an external USB DVD drive, and it seems to install properly up until the first install screen at the "installing windows" stage. I seem to keep getting the error "The file "asms"on Windows XP Professional Service Pack 3 CD is needed." I've tried to type in the direct path to the file (D:\i386) but that does not seem to work. I've also tried to open regedit in command prompt, but that doesn't work either. I am very confused, if anyone has any answers I'd love to hear thanks.
