Management Extension Component
Wake on LAN Header
The optional Wake on LAN header enables remote wakeup of the computer through
a network. Wake on LAN requires a PCI add-in network interface card (NIC) with
remote wakeup capabilities. The remote wakeup header on the NIC must be
connected to the onboard Wake on LAN header. The NIC monitors network traffic at
the MII interface and when it detects a Magic Packet it asserts a wakeup signal that
powers up the computer.
Note: For Wake on LAN, the 5-V standby line for the power supply must be
capable of delivering 5 V ±5 % at 720 mA.
Wake on Ring Header
The optional Wake on Ring allows the computer to wake from sleep mode when a
call is received on a telephony device, such as a modem, configured for operation on
COM1. The first incoming call powers up the computer. A second call must be made
to access the computer.
System BIOS
The BIOS (Basic Input Output System) is an important piece of software which is
stored in a ROM (Read Only Memory) chip inside the computer. It consists of the
basic instructions for controlling the disk drives, hard disk, keyboard and
serial/parallel ports. The BIOS also keeps a list of the specifications of the computer
in battery-backed RAM (also known as the CMOS RAM) and provides a special
Setup program to change this information.
The Motherboard uses a 4Mb Flash BIOS, which is stored in a flash EEPROM and
can be upgraded using a disk-based program. In addition to the BIOS, the flash
memory contains the Setup program, Power-On Self Test (POST), the PCI auto-
configuration utility, and is Windows 95-ready Plug and Play. This Motherboard
supports system BIOS shadowing, allowing the BIOS to execute from 64-bit onboard
write-protected DRAM.
The BIOS displays a message during POST identifying the type of BIOS and the
revision code.
