Onboard Serial Ports 1 ~ 4

Set the base I/O port address and IRQ for the onboard serial ports. Selecting "Auto" allows the
BIOS to automatically determine the correct base I/O port.

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]
