I/O Device Config
Onboard Serial Port 1 [3F8H/IRQ4], Onboard Serial Port 2 [2F8H/
IRQ3]
These fields set the addresses for the onboard serial connectors. Serial Port
1 and Serial Port 2 must have different addresses. Configuration options:
[3F8H/IRQ4] [2F8H/IRQ3] [3E8H/IRQ4] [2E8H/IRQ10] [Disabled]
UART2 Use Standard Infrared [Disabled]
When enabled, this field activates the onboard standard infrared feature
and sets the second serial UART to support the infrared module connector
on the motherboard. If your system already has a second serial port con-
nected to the onboard COM2 connector, it will no longer work if you en-
able the infrared feature. See Infrared Module Connector in
3.8 External Connectors. Configuration options: [Disabled] [Enabled]
Onboard Parallel Port [378H/IRQ7]
This field sets the address of the onboard parallel port connector. If you
disable this feature, Parallel Port Mode and ECP DMA Select configura-
tions will not be available. Configuration options: [Disabled] [378H/IRQ7]
[278H/IRQ5]
Parallel Port Mode [ECP+EPP]
This field allows you to set the operation mode of the parallel port. [Nor-
mal] allows normal-speed operation but in one direction only; [EPP] al-
lows bidirectional parallel port operation; [ECP] allows the parallel port to
operate in bidirectional DMA mode; [ECP+EPP] allows normal speed op-
eration in a two-way mode. Configuration options: [Normal] [EPP] [ECP]
[ECP+EPP]
ECP DMA Select [3]
This field allows you to configure the parallel port DMA channel for the
selected ECP mode. This selection is available only if you select [ECP] or
[ECP+EPP] in Parallel Port Mode above. Configuration options: [1] [3]
