DOS ain't dead

jemm final version 5.79 (Announce)

At last a bug was fixed in JemmEx that caused shrinking EMBs not to work correctly. It happens with Volkov Commander, for example - I always thought this a bug in VC, but finally realized it was a bug in JemmEx.

https://github.com/Baron-von-Riedesel/Jemm/blob/master/bin/JEMM579B.zip

changes:

02/02/2020: v5.79
- if physical address of DMA buffer was beyond 16M, its size was reset
to zero. This is no longer done.
- default linker is now JWlink.
- debug displays added for mode switch calls.
- Jemm will now use info returned by Int 15h, ax=E820h to mark regions
in the upper memory area as reserved.
- VME (virtual mode extensions) is now off by default; there exist CPUs
that claim to support VME but actually don't.
- JemmEx's built-in XMS host will now use up to 8 memory blocks listed
by ACPI (int 0x15, ax=0xe820). Previously it could just use the one
with base address 0x100000.
- fixed: shrinking an EMB didn't work correctly.

MS-DOS forever!
