- Yes, please post. I am interested in using DMA to transfer a MCGA 320x256
- -256 color image from an aux buffer to the actual screen regen buffer at
- 0A000h. It would be very nice to have DMA do this for me since copying the
- 64k buffer to the actual screen regen buffer (0A000h) is taking up too much
- processor load.
-
- If there is a way for DMA to do memory-memory (or memory-video buffer)
- transfers, please post how.

- Thanks,
