anyone know how many 1.44MB disks came with the release of MS-DOS 6.22? was 6.22 released as a standalone full instillation or as an upgrade only?

a quick search of ebay reveals alot of upgrade versions but few "full" versions and of these the number of disks seems to fluctuate

i also assume installation is the same as any other OS. you put the disk in at bootup?

the few copies of dos i've found don't seem to work for me i just get "not a system disk" when i try to install it so i'm looking for a real deal.
