Why can I setup LFB SVGA video modes in RAW DOS, if they work under Windows 95?
In this case you are compiling your program with the PMODE-based extender. This extender does not support function 800h of the DPMI host under RAW DOS, but under Windows 95 your program works since it uses the DPMI host of Windows 95. We recommend that you compile your programs with new PMODE/W, WDOSX and DOS/4GW based extenders, that support function 800h of the DPMI host even under RAW DOS.
