What is on the hard drive now? If Windows (any version) is already installed, copy the entire \i386 directory from the CD onto the hard drive. If nothing is on the drive, boot the system with a Win98 startup floppy, partition & format the drive, and then copy the i386 folder from there (I think xcopy can do this, right?) ... OR ... attach the hard drive to a system already running Windows and copy the directory.
Doing the copying in Windows is a little faster due to 32-bit instructions versus the 16-bit nature of DOS.
Once the files are on the hard drive, reboot with the Win98 floppy. Go into the i386 directory on the HD and run 'winnt' (I think that's the one).
