Onboard Parallel Port
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:
[Disabled]
[3BC/IRQ7]
Line Printer port 0
[278/IRQ5]
Line Printer port 2

Parallel Port M ode
[SPP]
Standard Parallel Port
[EPP]
Enhanced Parallel Port
[ECP]
Extended Capability Port
[ECP + EPP]
Extended Capability Port + Enhanced Parallel Port
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 sup
port both the ECP and EPP modes simultaneously.
EPP M ode 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 dis-
played 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 message will appear:
“
ECP
Mode Use DMA.
”
At this time, the user can choose between DMA channel [3] or
[1].
