Microsoft choice to limit non WIndows applications at some moment (beginning from Windows Vista). 
Nothing to do with DJGPP v2.05 (2.03 is affected in the same way). Fortunately M$ added workaround 
possibility after protests.

Search Google for: windows vista dpmi 32 MB limit

Or just take a look at: http://www.trnicely.net/misc/vista.html (first in results of Google search).

As far as I remember workaround worked immediately for me on Windows Vista Business SP1 32 bit 
without need to reboot as mentioned in some places. I have not tried it in Windows 7 32-bit as I 
only had 64 bit version. I do not know whether it works on Windows 8, 8.1 or 10 (32-bit versions only)

PS: This all is about 32-bit Windows only.
