To operate the onboard parallel port as Standard Parallel Port only, choose
[SPP]. To operate the onboard parallel port in the EPP mode simultaneously,
choose [EPP]. By choosing [ECP], the onboard parallel port will operate in ECP
mode only. Choosing [ECP + EPP] will allow the onboard parallel port to support
both the ECP and EPP modes simultaneously.

The ECP mode has to use the DMA channel, so choose the onboard parallel port
with the ECP feature. After selecting it, the following message will appear:
“
ECP Mode Use DMA.
”
At this time, the user can choose between DMA channel
[3] or [1].
