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.
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 14 shows the location of the battery.
The I/O controller provides the following features:
•
•
•
•
•
•
•
The BIOS Setup program provides configuration options for the I/O controller.
The board has one serial port header located on the component side of the board. The
serial port supports data transfers at speeds up to 115.2 kbits/sec with BIOS support.
The 25-pin D-Sub parallel port connector is located on the back panel. Use the BIOS
Setup program to set the parallel port mode.
