I don't know the whole story, but as I understand it a new config.sys option was added with Dos 3.x. It is called, I think, LASTDRIVE and is of the form LASTDRIVE=letter where 'letter' is the last drive letter to search. The default is 'E' which is why al==5. By the way, it is possible to have more than 26 drives. After Z:, however, the names become too bizarre to use easily. You get stuff like ]: as a drive name.
