Just another aside... on the question of .adf files (just .adf mind you)
neither dos nor os/2 nor aix use these files... They are used by the
internal configuration program of the PS/2 (aka the Reference disk)
and then stored in some sort of memory (semistatic ROM ? I dont really
remember..) within the PS/2 until the battery dies, is removed, or the 
configuration is changed...

soooooo.... I don't know about DOS 5.0 but thats the scoop on adf files...
