1.5 Power Supply
As with all computer products, a stable power source is necessary for proper and reliable
operation. It is even more important for processors that have high CPU clock rates. In areas
where noisy power transmission is present, you may choose to install a line filter to shield
the computer from noise. It is recommended to also install a power surge protector to help
avoid problems caused by power surges.
1.6 Super I/O
The Super I/O (NCT6106D chip) provides four high-speed, 16550 compatible universal
asynchronous receiver-transmitter (UART) serial communication ports, one of which supports
IrDA serial infrared communication. Each UART includes a 128 byte send/receive FIFO, a
programmable baud rate generator, complete modem control capability, and a processor
interrupt system. UARTs provide legacy speed with a baud rate of up to 115.2 Kbps as well
as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which support higher
speed modems.
The Super I/O provides functions that comply with ACPI, which includes support of legacy
and ACPI power management through a SMI or SCI function pin. It also features auto power
management to reduce power consumption.
The IRQs, DMAs and I/O space resources of the Super I/O can be flexibly adjusted to meet
ISA PnP requirements, which support ACPI and APM (Advanced Power Management).
