Yes there was a lot that Peter Norton documented for MSdos that wasn't
in the
manuals. Then again once the system configuration manuals disappeared
it was very uncommon to see MSdos off the PC platform but at one time
it was not unusual to see it on 8088/8086 equipped S100 machines.

Seems familiar with some other systems.
CP/M needed ^C when changing disks. So did MS-DOS! (sometimes)
I never could find ANYWHERE in any Microsoft manuals any mention of
pressing ^C when changing disks.
Yes, it did sometimes use the cached DIRectory instead of the newly
inserted disk!
