Parallel Port Mode
Set the parallel port mode. To operate the onboard parallel port as
Standard Parallel Port, choose SPP. To operate the onboard parallel
port in the EPP mode, choose EPP. By choosing ECP, the onboard
parallel port will operate in ECP mode. Choosing ECP + EPP will
allow the onboard parallel port to support both the ECP and EPP
modes simultaneously.
Settings: [SPP, EPP, ECP, ECP + EPP]
ECP Mode Use DMA
ECP (Extended Capabilities Port) has two DMA channels that it can
use. The default channel is 3. However, some expansion cards
may use channel 3 as well. To solve this conflict, change the ECP
channel to 1. Select a DMA channel for the port.
Settings: [1, 3]

Settings: [Disabled, FIR]
