A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When
the computer is not plugged into a wall socket, the battery has an estimated life of
three years. When the computer is plugged in, the standby current from the power
supply extends the life of the battery. The clock is accurate to ± 13 minutes/year at
25 ºC with 3.3 VSB applied.
NOTE
If the battery and AC power fail, custom defaults, if previously saved, will be loaded
into CMOS RAM at power-on.
When the voltage drops below a certain level, the BIOS Setup program settings stored
in CMOS RAM (for example, the date and time) might not be accurate. Replace the
battery with an equivalent one. Figure 1 on page 11 shows the location of the battery.
The Legacy I/O Controller provides the following features:
•
•
•
•
•
•
The BIOS Setup program provides configuration options for the Legacy I/O controller.
The serial port headers, COM 1 and COM 2, are implemented as two 10-pin headers on
the board. The serial port headers support data transfers at speeds up to
115.2 kbits/s with BIOS support.
