The setup.img file is used to create a boot disk for the 7200 mainframe.  
The diskette must be a 720K floppy.  The disk can not be read using DOS.  The 
7200 uses PSOS as the OS.

Insert a 720K floppy.  The floppy must be free of media errors.  If running 
Windows 2000, just use rawwritewin. Select the target drive and the image file.

The diskette created is used to low format the hard drive in the 7200. 

The 7200 mainframe must use the Miniscribe 8425, 8425F or the Kalok KL320.  To
use the setup program, the drive MUST have NO physical errors.

Place the new disk into the 7200 and turn on the scope, or reset the scope.
Follow the menus to format the disk.

Do not reformat a disk that has errors or was already formatted!!
