|No version of MS-DOS or PC-DOS i have checks for the install label. A base version might not install if the installed DOS is different to the one being installed (ie you attempt to put PC-DOS 6.1 on PC-DOS 5.0).|
You can quite simply copy all of the files from the diskettes to a single drive (which can be a subdirectory!), and run setup from there. If the DOS is an upgrade, you can first SYS the c:\ drive with some acceptable DOS (eg PC-DOS or MS-DOS).
For example, i have a cdrom, on which i have the files copied from the various dos versions of MS-DOS 5,0, 6.0, 6.2, 6.21, 6.22, and PC-DOS 5.0, 5.02, 6.00, 6.10, 6.30, 7.00 and 7.00B. You simply sys the c:\ drive, and run the install program from the load directory. So to install, eg pc-dos 6.10, you change to eg
and follow the bouncing ball.
It works with MS-DOS as well.
