[F] Integrated I/O Controller
On the motherboard, serial ports, parallel port and floppy drive is integrated into a single chip. The
I/O port allows you to configure through the BIOS setup. This integrated I/O chip provides:
•
Plug-and-Play, Version 1.0a compatible.
•
Built In RTC devices
•
Supports two 360K, 720K, 1.2M, 1.44, 2.88M floppy disk drives
•
One multi-mode parallel port, which can be configured as standard (SPP) mode,
enhanced (EPP) mode, high speed (ECP) mode.
•
Supports two 16C550 compatible enhanced serial ports.
•
Supports IrDA or ASKIR infrared interface.
[G] Flash BIOS
The flash BIOS allows user have more flexibility to upgrade their motherboard. The flash BIOS can
be programmed by software easily. For the latest BIOS upgrade information, please feel free to visit

[H] PCI Add-in Board Connectors
This motherboard provides four 32-bit PCI slots with up to 133MB/sec burst data transfer rate.
[I] ISA Add-in Board Connectors
This motherboard provides three 16 bit ISA slots, which allows backward hardware compatibility.
[J] Front Panel Function Connectors
All the front panel indicator, speaker, and switch functions are grouped into an on-board 26-pin panel
function connector.
[K] 82371AB PCI/ISA IDE Accelerator (PIIX4)
The Intel 82371AB is a 392-pin BGA package IC which provides the following features:
•
Interface between the PCI local bus and ISA bus.
•
Supports for 2 Universal Serial Bus (USB) ports.
•
Integrated fast IDE interface, which supports up to 4 devices. With separated
Master/Slave mode support, it provides data transfer rate up to 33 MB/sec in Ultra-
DMA mode. In addition, it also integrated an 8 x 32-bit buffer for Bus Master IDE
PCI burst transfers, which further enhanced the system performance.
•
Ultra-DMA controller with Fast Type-F DMA
•
Counters/Timers, which provides advanced power management with programmable
system management interrupt (SMI).
[L] Infra-Red (IR) Support
A 5-pin interface on the front panel I/O connector is provided to allow connection to a Hewlett
Packard HSDSL-1000 compatible Infrared (IrDA) transmitter/receiver. Once the module is connected
to the front panel I/O header, Serial port 2 can be re-directed to the IrDA module. When configured
for IrDA, the user can transfer files to or from portable devices such as laptops, PDA’s and printers
using application software such as LapLink. The IrDA specification provides for data transfers at
115kbps from a distance of 1 meter. Support for Consumer infrared (ASK-IR) is also included, please
refer to your IR equipment for more detailed information.
