2.8 Real-Time Clock Subsystem
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 shows the location of the battery.
2.9 Legacy I/O Controller
The Legacy I/O Controller provides the following features:
 Two serial port headers
 Two serial port connectors on the back panel
 One parallel port header with Enhanced Parallel Port (EPP) support
 Serial IRQ interface compatible with serialized IRQ support for Conventional PCI
