1.6 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 that you also install a power surge protector to
help avoid problems caused by power surges.
1.7 Super I/O
The ASpeed AST2600 Super I/O provides one high-speed, 16550 compatible Universal
Asynchronous Receiver/Transmitter (UART), which support serial infrared communications.
This UART includes a send/receive FIFO, a programmable baud rate generator, complete
modem control capability and a processor interrupt system. This UART provides legacy speed
with 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 (Advanced Configuration and Power
Interface), which includes support of legacy and ACPI power management through the System
Management Interrupt (SMI) or System Control Interrupt (SCI). 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).
