I only know that it exist but never programmed DMA. If someone have a short example how to use DMA under DJGPP to transfer data from program space to peripheral memory mapped buffer like LFB i§d like to see it.
I normaally use movedata to transfer offscreen buffer to mapped physical memory of LFB and on later HW (PII + AGP) it's pretty fast.

DOS gives me freedom to unlimited HW access.
