Hi,
 
Could some kind soul out here in net-land kindly furnish me with the
information needed to program the DMA registers for 16-bit DMA requests
in the AT-286?
 
I have what appears to be all the info needed to program the primary DMA
controller for 8-bit requests, but I need the information needed to
control the secondary DMA controller to accomplish 16-bit port to memory
(device to memory) transfers. This is, I understand now, the only way to
accomplish true 16-bit data transfer to/from ports.
 
Any help will be greatly appreciated..
 
Mail me at "kmeyer@daisy.ee.und.ac.za" preferably.
ta
Kevin
