P6F104 User’s Manual
1.11 Real-time Clock, CMOS RAM and Battery
The integrated real-time clock (RTC) provides a time of day clock,
and an 85-year calendar with alarm features. P6F104 also has 242
bytes battery backed CMOS RAM which stores the system setup
information and password. The RTC and CMOS RAM can be set
via the BIOS SETUP program. The content of the CMOS RAM can
be cleared by placing a shunt to short pin2 and pin3 of JP23 for 5
seconds when the system power is off.
A coin-cell style Lithium CR2032 battery is used to provide power
to the RTC and CMOS memory. The battery has a three year life if
the system is not powered up. When the system powers up, the
power for the RTC and CMOS RAM is supplied from the 5 V power
supply to extend the life of the battery.
1.12 IrDA Infrared Support
A 5-pin header connector is used to connect a Hewlett Packard
HSDSL-1000 compatible IrDA or Sharp ASKIR Infrared module.
Once the module is installed, the user can use application software
such as Laplink to transfer files between the computer system and
portable devices such as laptops and printers.
1.13 Power Management
The integrated DPMA (Dynamic Power Management Architecture)
features in the Intel 810 AGPSet go far beyond the original vision of
the “Green PC” to create exciting new application models for the
“OnNow” PC platform. The “OnNow” PC is a PC which is always
on and ready for use but appears to be off when not in use. The
P6F104 not only complies with EPA, APM1.2 and ACPI (Advanced
Configuration and Power Interface)1.0, but also provides the
following power management features.
-
Power-on by a modem ring in or a Alarm
System could be powered on by phone ring, or by software that has
requested the PC to wake up at a preset time.
