SPP/EPP/ECP/ECP+EPP
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.
EPP Mode Select
The onboard parallel port is EPP Spec. compliant, so after the user chooses
the onboard parallel port with the EPP function, the following message
will be displayed on the screen: “EPP Mode Select.” At this time either
EPP 1.7 spec or EPP 1.9 spec can be chosen.
ECP Mode Use DMA
The ECP mode has to use the DMA channel, so choose the onboard
parallel port with the ECP feature. After selecting it, the following mes-
sage will appear: “ECP Mode Use DMA.” At this time, the user can
choose between DMA channel 3 or 1.
