Increased allowed memory size. Required some BIOS extensions to be implemented - they are documented in Ralf Braun Interrupt List:

Tested with Windows 95. The E820 routine (memory map) was taken from DOSBox-X (with cleanups by me), which inherited it from DOSBox Daum.

Maximum memory size can probably be increased even further, but starting from around 480 MB Windows 95 starts causing problems (see https://en.wikipedia.org/wiki/Windows_95#System_requirements), and 384 MB is already a lot.
