*** Galacticomm has included its own custom GALUP.EXE. Although patches for both Large and Huge memory model are included on the disk, Galacticomm only will support Huge memory model. The following is a list of differences that can be found with this release: *** Support for Borland C++ has been added. I guess I need an old 486 to make this work. I have also tried reviving my old BBS on an old AMD K6-2 500MHz computer running DOS 6.22 natively, and it still fails due to the fact that it can't run this OS286 DOS Extender properly. A personal note: I have not been successful in getting The MajorBBS v5.31 to run under DOSBOX, VMware, or VirtualBox on modern systems. It may be useful with other software, but at the very least, if you were running The MajorBBS v5.31, this is the program you needed to allow your BBS to operate beyond the 640k DOS memory barrier.

This particular version of the DOS Extender was custom tailored for people who were running The MajorBBS v5.31 by Galacticomm.
