- I am lead to beleive it is possible to do DMA transfers RAM to RAM.
- If possible, could somebody please post a summary of how to do it on an AT.
- Information on how long such transfers take would also be appreciated.
-
- My motivation is to write a video update routine to move data to and from
- video ram independent of the cpu.
-
- Thanks in advance.
