Real Time Clock Wake-up Alarm
The PC is perceived to be off when not in use, but is still capable
of responding to previously scheduled wake-up events. The user
can set up a timer to wake-up or shutdown the system at some
predetermined date or time of the month.
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function
as a system suspend button. When the user presses on the
power button, the system will enter a SoftOff state. The monitor
will be suspended, and the hard drive will spin down. Pressing
the power button again will cause the whole system to wake-up.
During the SoftOff state, the ATX power supply provides power to
keep the required circuitry on the system alive. In case the
system malfunctions and you want to turn off the power, just
press down on the power button for approximately 4 seconds.
The power will turn off and no power is provided to the
motherboard.
External Modem Ring-on
Wake-up events can be triggered by a device such as the external
modem ringing when the system is in SoftOff state. When the
modem rings, the system behaves as if a user pressed the
PW_ON button.
1-4 Chipset Overview
The 440LX chipset was developed by Intel as the ultimate
Pentium II processor platform targeted for emerging 3D graphics
and multimedia applications. Along with System-to-PCI bridge
integrated with optimized DRAM controller and data path, the
chipset introduces the Accelerated Graphics Port (AGP) interface.
AGP is a high performance, component level interconnect targeted
at 3D applications and is based on a set of performance en-
hancements to PCI. The I/O subsystem portion of the 440LX
platform is based on the PIIX4, a highly integrated version of
Intel's PCI-to-ISA bridge family.
The 440LX PCI/AGP Controller (PAC) system bus interface sup-
ports up to two Pentium II processors. It provides an optimized
72-bit DRAM interface (64-bit data plus ECC). This interface
supports 3.3V DRAM technologies. The PAC provides the inter-
