1 Implementation of Magic Packet-Ready Motherboard Application Note This Application Note provides a description of building a Magic Packet-ready motherboard for Network Adapter applications. It also presents the standard signals and connectors that are used in a motherboard. INTRODUCTION Magic Packet technology is implemented as a system solution. The complete system solution is comprised of the motherboard, network adapter card, standby supply, BIOS and network management software. The motherboard accepts the wake-up signal and performs the power management protocol. The wake-up signal will wake the motherboard either from standby or suspend mode. In standby mode, the computer is alive and kicking, with power to the entire motherboard. The low power consumption in this mode is accomplished by slowing down the processor clock, spinning down the hard drives, and putting the monitor in a low power consumption state. In suspend mode, the computer is usually brought to a complete halt. The CPU is stopped and the power may even be removed. The entire system is powered down, except the power management circuit which in many cases is a Super I/O or a keyboard controller chip and the Ethernet Controller which receives the Magic Packet that wakes up the system. POWER MANAGEMENT CIRCUIT Many PCs have already implemented a remote wakeup from standby mode via modem ring. When a modem is called for an incoming FAX or , the RI (Ring Input) signal of COM port is asserted. The RI signal is an input to a Super I/O chip like a National Semiconductor DP Figure illustrates an example of a power management circuit. +5VCC_S ON/OFF 0K 0. 0K 0K PS_ON PWRGD +5VCC_S +2V -2V -5VCC_S +5VCC_S +5VCC_S +5VCC_S POWER SUPPLY HEADER COM_RI LAN WAKE-UP 0K DCD SIN SOUT DTR DSR RTS CTS RI PC87307 IRQ IRQ2 IRQ3 SMI PS_ON 2 3 POWER SUPPLY HEADER LAN WAKE-UP NOTE: All gates shown are powered by Figure. 0K Figure : An Example of Remote Power ON/ WAKE-UP Control Circuit on Motherboard MAGIC PACKET HEADER PART NUMBER AMP An Example of Remote Power ON/WAKEUP Control Circuit on Motherboard 2383B- Publication# 2383 Rev: B Amendment/0 Issue Date: April 997 This document contains information on a product under development at Advanced Micro Devices.

2 This RI signal is processed by a Super I/O, which in turn sends a System Management Interrupt (SMI) if the system is waking-up from standby mode. If the PC is waking-up from suspend mode, the Super I/O toggles the soft power-on of the power supply. The waking signal, in this case, the LAN WAKE-UP can be OR ed with MODEM RING. Another option is to input the LAN WAKE-UP to the RI pin of COM2 port. The momentary ON/OFF switch is connected directly to the soft power-on (PS_ON) of the power supply. This can be placed as an input to the Super I/O chip in order to support the BIOS power down policy of the APM or ACPI specification. POWER SUPPLY REQUIREMENT The support for power management circuit requires the incorporation of a standby supply with built-in soft power-on. The standby supply will power the power management circuit and the Ethernet controller circuit. The power requirement for a typical power management circuit is 00 ma and for the Ethernet circuit is 450 ma (in Magic Packet mode). Therefore, the recommended capacity is at least 550 ma. Appendix A lists power supply vendors. The power supply should provide PWRGD and PS_ON signals. A 550 ma standby supply can be special ordered. SIGNAL CONNECTORS Figure 2 shows the recommended connectors and signals in a motherboard. The standby supply post header presently being used is a standard 3-pin Amp connector. The additional connector to be installed is J2, which is a 3-pin straight-through post header. The mechanical drawings and specifications for the connector are shown in Appendix B.

It can be easily added to a green enabled computer. The main requirements are the power management circuit, which is already popular in many computers, a standby power supply, and one extra connector and cable. For a small investment, it represents a strong value proposition. Implementation of Magic Packet-Ready Motherboard 3
