Parallel Port ECP DMA Channel

If your system supports ECP parallel port mode and you have the port set to use ECP, you must use this setting to assign a DMA channel for use by the port. The usual options are "DMA 1" and "DMA 3".

Note: This setting is either locked out or ignored if the parallel port is disabled, or if the parallel port mode is not set to ECP.

Warning: Some BIOSes allow this to be set to DMA channel 2 as well, which is normally reserved for the floppy disks. This will often create a resource conflict if chosen.
