The LPC interface on the Super I/O complies with the Intel® Low Pin Count Specification
Rev. 1.0. The LPC interface supports both LDRQ# and SERIRQ protocols as well as PCI
PME# interfaces.

CyberResearch® Motherboards MXGA Series

2.8.3.2 Super I/O 16C550 UARTs

The onboard Super I/O has two integrated 16C550 UARTs that can support the following:

 Two standard serial ports (COM1 and COM2)
 IrDa 1.0 and ASKIR protocols

Another two chipsets connected to the LPC bus provided connectivity to another two serial
port connectors (COM3 and COM4).

2.8.3.3 Super I/O Enhanced Hardware Monitor

The Super I/O Enhanced Hardware Monitor monitors three thermal inputs, VBAT
internally, and eight voltage monitor inputs. These hardware parameters are reported in
the BIOS and can be read from the BIOS Hardware Health Configuration menu.

2.8.3.4 Super I/O Fan Speed Controller

The Super I/O fan speed controller enables the system to monitor the speed of the fan.
One of the pins on the fan connector is reserved for fan speed detection and interfaced to
the fan speed controller on the Super I/O. The fan speed is then reported in the BIOS.

2.8.3.5 Super I/O Parallel Port

The Super I/O parallel port (LPT) supports standard mode, enhanced mode and
high-speed mode parallel port devices. The LPT is compliant with the following LPT
modes.

 Standard mode

o Bi-directional SPP compliant

 Enhanced mode

o EPP v1.7 compliant
o EPP v1.9 compliant

 High-speed mode

o ECP, IEEE 1284 compliant

2.8.3.6 Super I/O Keyboard Controller

The Super I/O keyboard controller can execute the 8042 instruction set. Some of the
keyboard controller features are listed below:

 The 8042 instruction is compatible with a PS/2 keyboard and PS/2 mouse
 Gate A20 and Keyboard re set output
 Supports multiple keyboard power on events
 Supports mouse double-click and/or mouse move power on events

2.9 Environmental and Power Specifications

2.9.1 System Monitoring

Three thermal inputs on the MXGA Super I/O Enhanced Hardware Monitor the following
temperatures:

 System temperature
 Power temperature
 CPU temperature

Eight voltage inputs on the MXGA Super I/O Enhanced Hardware Monitor the following
voltages:

 Vcore
 +2.5V
 +3.3V
 +5.0V
 +12.0V
 DDR Vtt
 +1.5V
 5VSB

The MXGA Super I/O Enhanced Hardware Monitor also monitors the following voltages
internally:

 VBAT

CyberResearch® Motherboards MXGA Series

The MXGA Super I/O Enhanced Hardware Monitor also monitors the following fan
speeds:

 CPU Fan speed

The values for the above environmental parameters are all recorded in the BIOS
Hardware Health Configuration menu.

2.9.2 Operating Temperature and Temperature Control

The maximum and minimum operating temperatures for the MXGA are listed below.

 Minimum Operating Temperature: 0ºC (32°F)
 Maximum Operating Temperature: 60°C (140°F)

A cooling fan and heat sink must be installed on the CPU. Thermal paste must be
smeared on the lower side of the heat sink before it is mounted on the CPU. Heat sinks
are also mounted on the northbridge and southbridge chipsets to ensure the operating
temperature of these chips remain low.

2.9.3 Power Consumption

3.1 Anti-static Precautions

WARNING:

Failure to take ESD precautions during the installation of the MXGA
may result in permanent damage to the MXGA and severe injury to the
user.

Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the MXGA. Dry climates are especially susceptible to ESD. It is critical that the
following anti-static precautions are strictly adhered to whenever handling the MXGA or
any other electrical component.

 Wear an anti-static wristband - Wearing a simple anti-static wristband can

help to prevent ESD from damaging the MXGA.

 Self-grounding - Touch a grounded conducting material before handling and

periodically while handling the MXGA.

 Use an anti-static pad - When configuring the MXGA, place it on an

antic-static pad to reduce the possibility of ESD damage.

 Only handle the edges of the MXGA - When handling the MXGA, hold it by

its edges.
