So much for compatibility... ;-)

But what has happened with the output above B147h:00CCh?
Does MEM /A skip this?
And what happens when you use QEMM under DR-DOS?
Which version of QEMM and MS-DOS?
Is this dependent on a specific configuration or does it
happen all the time? I would be particularly interested in
the contents of the MCB at B147h:0000h

In any way it seems something very strange has happened to
the MCB chain, and possibly the next few hundred bytes.
Can you send me a DEBUG memory dump of the following
next kilobyte via private mail? Thanks.

Greetings,

 Matthias
