Onboard Parallel Port
This option is used to assign the I/O address and interrupt request (IRQ) for the onboard parallel
port.
Parallel Port Mode
This item enables you to set the data transfer protocol for your parallel port. There are four
options: SPP (Standard Parallel Port), EPP (Enhanced Parallel Port), ECP (Extended Capabilities
Port), and ECP + EPP. SPP allows data output only. ECP and EPP are bi-directional modes, allowing
both data input and output. ECP and EPP modes are only supported with EPP- and ECP-aware
peripherals.
ECP Mode Use DMA
When the onboard parallel port is set for ECP mode, the parallel port can use DMA3 or DMA1.
