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
