4.00 4.01

MS-DOS

Summary:

The “Microsoft MS-DOS User’s Guide and User’s Reference” for MS-DOS Version 4.00 states on Page 20 that to install MS-DOS on a hard disk, you will need one 5.25-inch 360K disk or one 3.5-inch 720K disk. These media specifications are identical even if your machine has a 5.25-inch, 1.2 MB or a 3.5-inch, 1.44 MB disk drive. The installation procedure, SELECT.EXE, will fail if a 1.2 MB or 1.44 MB disk is used.

More Information:

During the install process, the SELECT utility makes a copy of the INSTALL disk onto the user-supplied SELECT COPY disk. Because the DISKCOPY utility is used to perform this task, the source and destination disks must be of compatible types. The MS-DOS Version 4.00 distribution disks are in either 360K or 720K format; therefore, they will require 320K or 720K disks during the installation process.
