IDE PIO Mode
-
IDE Programmed I/O Mode - This
setting relates to the speed at which the hard drive is
able to transfer data, up to 16.6MB/second for Mode 4
drives. Available settings are
Auto
,
0
,
1
,
2
,
3
, or
4
. As
with the
Type
setting,
Auto
is the preferred choice, in
that the supported PIO Mode is read directly from the
hard drive. Be sure not to use a PIO Mode higher than
what the drive actually supports. This could result in
loss of data.

IDE UDMA (Ultra DMA) Mode
-
The chipset used for this mainboard improves the
IDE performance by implementing UltraDMA/33 Bus Mastering IDE which can handle
data transfer up to 33 Mbyte/sec. This UDMA technology is downward compatible with
existing ATA-2 IDE. So there is no upgrade required for current hard drives and cabling.
*
Auto is
default.
USB Keyboard Support -
This item allows you to enable or disable the USB keyboard
driver within the onboard BIOS. The keyboard driver simulates lagacy keyboard command
and let you use USB keyboard during POST or after boot if you don’t have USB driver in
the operating system.
Init AGP Display First -
When your system has an AGP card coexisting with other PCI or
ISA VGA cards, enabling this option tells your system to use the AGP card.
Onboard FDD Controller
-
Enables or Disables the on-board Floppy Disk Controller.
Onboard Serial Port 1
-
With this option, the on-board Serial Port 1 can be Disabled, or
set to 3F8/IRQ4, 2F8/IRQ3, 3E8/IRQ4 or 2E8/IRQ3. (*
Auto
is Default)
Onboard Serial Port 2
-
With this option, the on-board Serial Port 2 can be Disabled, or
set to 3F8/IRQ4, 2F8/IRQ3, 3E8/IRQ4 or 2E8/IRQ3. (*
Auto
is Default)
InfraRed/COM2 Selected
-
By default, this field is set to UART COM2, which directs the
second serial port UART to support the COM2 serial port. Choosing
SHARP IR
(
ASKIR
)
or
IrDA SIR
(
HPSIR
), will activate the on-board infrared feature and redirect the second
serial port UART to support the infrared module connector on the mainboard.
Onboard Parallel Port
-
With this option, the on-board Parallel Port can be Disabled, or
set to 378/IRQ7 (*Default), 3BC/IRQ7 or 278/IRQ5.
Onboard Parallel Port Mode
-
Sets the operating mode of the parallel port. Options are:
Normal, EPP (Enhanced Parallel Port) / Normal, ECP (Extended Capability Port)
and
ECP/EPP (default).
ECP Mode Use DMA
-
Options are 1 and 3. This field is available only when one of the
two following options in
Parallel Port Mode
is selected: ECP or ECP/EPP.
