How to get video memory address to draw under DPMI, 32-bit protected mode? The video mode is 13h (320x200x8). I tried 0A0000, but it didn't work.

BUG symptoms ???

$000A'0000 is correct. Make sure your segment is ZERO-based (USEDPMI.ASM isn't). Also, check the sticky thread on the top and examples linked from there, is case of further trouble post offending code.
