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.

with the ECP feature. After selecting it, the following message will appear:
“

At this time, the user can choose between DMA channel
[3] or [1].
