Yes, MS-DOS 6.22 has been around, and everyone and their brother has
the upgrade disk, but here is the full install straight from the fine
folks at the factory.  Some people prefer to have full installs, and
thats why I am putting this up, even though it is from 1994.

The files:

DOS622_1.ZIP
DOS622_2.ZIP
DOS622_3.ZIP

are respectively disks 1, 2, and 3, and the new OS should be installed from
disk.  Label 3 disks, DISK      1, DISK      2, DISK      3.  Next Unzip the
three ZIPS listed above to their properly labeled disks.  Now reboot, with 
Disk 1 in A drive and voila!  SETUP time.  
NOTE: there are 6 spaces (ASCII 32) between DISK......1 and its respective 
number.  

Enjoy, spread, modify, Merry Hex Mass.
