Hello everyone!
Long (long...) time ago I was using a very useful feature of DJGPP.
I'm talking about the linear frame buffer emulation for video cards
with bank switching function only.
Now this feature has been removed and I thought it was caused by DPMI
server (no functions available for doing that).
But after reading the functions available in DPMI I got the impression
it could be done, at least a small part.
I think it would be interesting to add a new selector by default,
maybe called _vga_ds, in addition to _dos_ds, _my_ds, etc.
Or I could be simply wrong and this method can't be done right now.

Sincerely,

Carlo.
