Parallel Port Mode
SPP : Standard Parallel Port
EPP : Enhanced Parallel Port
ECP : Extended Capability Port
ECP + EPP: Extended Capability Port + Enhanced Parallel Port
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 simultane-
ously.
