Onboard Parallel Mode

SPP : Standard Parallel Port
EPP : Enhanced Parallel Port
ECP : Extended Capability Port
SPP/(EPP/SPP)/
ECP(ECP/EPP)
There is a built-in parallel port on the
on-board Super I/O chipset that
provides Standard, ECP, and EPP
features. It has the following options:
Line Printer port 2
Line Printer port 1
To operate the onboard parallel port as
Standard Parallel Port only, choose
"SPP." To operate the onboard parallel
port in the ECP and SPP modes simulta-
neously, choose "ECP/SPP." 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 select-
ing it, the following message will appear:
"ECP Mode Use DMA" At this time the
user can choose between DMA chan-
nels 3 or 1. 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.
