Which DOS 6.22 files are critical and why? Where can I find out what each line of text means in the files?

Critical in what sense? Text in which files? A bit more information about the context would be most helpful in answering your questions.

The critical files are ibm$sys, ibm$dos, and command.com!

You need all three of these files to work! These files are the actual operating system that are required to boot DOS.

The ibm$sys and ibm$dos are hidden system files that you normally can not see.

If you have the full set of diskettes for DOS 6.22 then you have the DOS help files.

Load all of DOS 6.22 on a hard drive and you can type HELP to get a list of the commands.

Then you can type HELP CONFIG and get specific help oneach command.

If you want further information the best place to get it is to go to the Library and check out a book for MS-DOS.

you need the following files on your hard drive all the time to even use it.

command.com - MS-DOS interpreter
io.sys - major system file, 1st file bios reads to determine DOS is installed
msdos.sys - the 2nd file that is read.

On the MS-DOS 6.22 installation disks, there should be a file called help.com which requires qbasic.exe run help.com (just type help) and the help appears. The help is basically a listing of alot of MS-DOS commands you can use.
