The following is the requirements of the Netwaker, but also the remote boot requirements, the general now has support.

1. Hardware Requirements

Realize the network boot, need motherboard, network card, power supply 3 device support. First, you need to check the motherboard operating instructions to see if the motherboard supports wake-up on Internal Modem (WOM) or wake-up on LAN (WOL) technology, if the support indicates that the motherboard supports remote boot. Can realize remote wake, one of the most important part is the network card support WOL, the remote wake-up computer network card must support WOL, and to wake up the other computer network card does not have to support WOL. In addition, when a computer is installed with multiple network cards, only one of the pieces must be set to wake up remotely.

In addition, the computer must have an ATX 2.03 compliant power supply, and the +5vstandby current should be at least 720mA. Some early power supplies may only be designed to 500mA, and when the network is switched on, some of the larger NICs may fail to boot.

2.CMOS settings

First, the CMOS and network card settings are required to start the computer and enter the CMOS parameter settings. Select the Power Management Setup menu to enable the remote wake-up feature of this computer by setting the "Wake Up" and "Wake on PCI Card" entries to "enable". Some network cards require a jumper to set the "Wake-on-lan" function to "Enable".

Plug both ends of the WOL cable into the network card and the motherboard's 3-pole socket and connect the network card to the computer motherboard. If the motherboard supports the PCI 2.2 standard, simply turn on the "Wake on PCI Card" feature, without having to use the WOL cable connection. Then start the computer, install the NIC driver, and complete the network connection settings for the network card.
