It sets the items related to the I/O ports, such as the IDE controller, the transfer mode, the serial
ports and the parallel port.
IRQ#/DMA#
Assigned To Enables the IRQ and DMA assignations to be set manually when [Resource Controller By] is set
at [Manual]. The [Auto] setting is used when the required assignations cannot be selected
owing to legacy devices that do not support Plug & Play being in use. It is necessary to ensure
that no resource conflicts arise when setting this parameter. This is especially applicable when
all IRQ resources are required for serial ports and other ISA devices. On the other hand, the IRQ
resources are controlled by the PCI steering holder with PCI devices.
Used MEM Base
Addr It sets the base address of the UMB in the expanded area (768K to 896K). Normally set at N/A. If
the values are specified, the values mean the base address.
Used MEM
Length It sets the memory size when [Used MEM Base Addr] is set to other than N/A. Normally 8K bytes.
If the value is changed, the value is the memory size.

Items Description
IDE HDD Block
Mode It sets the sector numbers related to the block transfer mode (The block transfer mode reduces
the number of interruptions by the multi sector transfer to enable higher transfer speed).
Normally set at [Enabled].
On-chip PCI IDE It sets whether to use or not use the IDE controller on the motherboard (chipset). Two 2.5 inch
HDDs can be connected to the primary PCI
. It is also possible to connect both a CD-ROM and
a compact-flash to the secondary PCI IDE. It is possible to make available the IRQ with system
configurations that do not use IDE devices (drives) by disabling both the primary and
secondary parameters.
IDE Primary
Master PIO It sets the transfer mode with the PIO of the IDE device connected to the IDE interface (Master).
This parameter is normally set at [Auto] and automatically sets up the optimum mode with the
auto detection function on the BIOS during POST.
IDE Primary
Slave PIO It sets the transfer mode with the PIO of the IDE device connected to the IDE interface (Slave).
This parameter is normally set at [Auto] and automatically sets up the optimum mode with the
auto detection function on the BIOS during POST.
IDE Primary
Master UDMA It sets the transfer mode with the DMA of the IDE device connected to the IDE interface
(Master).
This parameter is normally set at [Auto] and automatically sets up the optimum mode with the
auto detection function on the BIOS during POST.
IDE Primary
Slave UDMA It sets the transfer mode with the DMA of the IDE device connected to the IDE interface (Slave).
This parameter is normally set at [Auto] and automatically sets up the optimum mode with the
auto detection function on the BIOS during POST.
USB Keyboard
Support It enables or disables a USB Keyboard Legacy Support setting. If Legacy Support Enables is
selected, it is necessary to set the [Assign IRQ For USB] stting to Enable.
Onboard LAN
Support It sets enable or disable an Onboard Ethernet usage.
Onboard
Parallel Port It sets the I/O address and IRQ number of the parallel port (LPT1) on the motherboard.
This parameter can be selected from 3BC/IR7, 378/IRQ7 (Default), 278/IRQ5, and [Disabled].
The I/O address and IRQ number will be available if this parameter is set at [Disabled].
Parallel Port
Mode It sets the parallel port mode. This parameter can be selected from SPP, EPP1.9+SPP, ECP,
ECP+EPP1.9, Normal, EPP1.7+SPP and ECP+EPP1.7. It is necessary to set [DMA Channel] in [ECP
Mode Use DMA] when the [ECP Mode] has been selected.
