Onboard Parallel Port
This specifies the I/O port address and IRQ of the onboard parallel port. Settings: [Disabled, 378/IRQ7,
278/IRQ5, 3BC/IRQ7]
6.18.3.
Parallel Port Mode
Set the parallel port mode. To operate the onboard parallel port as Standard Parallel Port, choose SPP.
To operate the onboard parallel port in the EPP mode, choose EPP. By choosing ECP, the onboard
parallel port will operate in ECP mode. Choosing ECP + EPP will allow the onboard parallel port to
support both the ECP and EPP modes simultaneously.
Settings: [SPP, EPP, ECP, ECP + EPP]
6.18.4.
ECP Mode Use DMA
ECP (Extended Capabilities Port) has two DMA channels that it can use. The default channel is 3.
However, some expansion cards may use channel 3 as well. To solve this conflict, change the ECP
channel to 1. Select a DMA channel for the port.
Settings: [1, 3]
