I hope T-R-A will answer your request, anyway to do a MS DOS upgrade install just google to find a DOS boot disk ver 5.00 or earlier and after installed aply your incremental 6.22 diskettes.

MS DOS is command.com, io.sys and msdos.sys, i.e. the shell, the bios and the kernel, all other modules are usefull stuff, bur not necessary to keep the computer running.

Gee, being called on by name now...must be famous (not)...

I'm assuming also you have no other operating system on the machine in question (otherwise you'll lose everything on it)...

If memory serves (it's been a long time)....

1. After making sure disk geometry is correctly setup in BIOS---Boot machine with Disk 1 of the upgrade set (it should already be bootable). Stop the upgrade attempt (it'll usually just fail on it's own).

2. Leave Disk 1 in drive and FDISK C: drive as normal.

3. FORMAT(also on disk 1) previously FDISKed drive using command (without quotes)
"FORMAT C:/S/U"

Using the "S" switch copies the system files to the drive after formatting; the files the upgrade looks for when it's upgrading (as I mentioned years ago, you're essentially upgrading DOS 6.22 to DOS 6.22).

The "U" switch is an unconditional format (i.e.---can't go back, but if it's a fresh drive, it may not be needed---I've just never done it without it).

4. Run the upgrade disks as normal (i.e. reboot or run "A:/setup.exe").

Again, it's been a while, so bear with an aging memory.
