The SMI signal generating module 130 is a function module pre-set in the I/O control chip 12, which can receive the above-mentioned GPIO (General-Purpose Input/Output) in the I/O control chip (Super I/O chip) 12. When the PME signal sent by the PME packet processing module 120 is sent, an SMI (System Management Interrupt) signal is sent immediately.

The SMI signal judging module 140 is a function module preset in the BIOS, which can judge whether the SMI signal sent by the above-mentioned SMI signal generating module 130 is triggered by the PME signal; if so, send a restart signal OnCtrl.

If the network computer platform 10 is currently in a power-off state, then the restart signal OnCtrl sent by the SMI signal judging module 140 can make the power supply module 13 in the network computer platform 10 be turned on, allowing the network computer platform 10 to carry out a boot procedure; The power supply of computer platform 10 has been turned on but downtime situation takes place at present, then the restart signal OnCtrl that SMI signal judging module 140 sends can make host unit 14 (being central processing unit and operating system thereof) in network computer platform 10 execute a The reactivation program (reboot) allows the network computer platform 10 in the downtime state to resume normal operation.

But whether it is a remote wake-up procedure or a remote restart procedure, the user's operation method is the same; that is, it only needs to send a PME packet through the PME packet sending module 110 in the management platform 30 .

The implementation process of the network computer platform remote restart method of the present invention is: the PME packet sent by the PME packet sending module 110 will be transmitted to the network chip 11 in the network computer platform 10 through the network system 101, so that the PME packet in the network chip 11 The processing module 120 can receive the PME packet, and send a PME signal to the I/O control chip 12 in response. This will cause the SMI signal generating module 130 in the I/O control chip 12 to send out an SMI signal in response to the PME signal. Then, the SMI signal judging module 140 in the BIOS is responsible for judging whether the SMI signal sent by the SMI signal generating module 130 is triggered by the PME signal; if so, a restart signal OnCtrl is sent. If the network computer platform 10 is currently in shutdown state, then the restart signal OnCtrl sent by the SMI signal judging module 140 can make the power supply module 13 in the network computer platform 10 be turned on and allow the network computer platform 10 to carry out a boot procedure; The power supply of the network computer platform 10 has been turned on but a downtime situation occurs at present, then the restart signal OnCtrl sent by the SMI signal judging module 140 can make the host unit 14 in the network computer platform 10 carry out a reactivation procedure, so as to allow the downtime to occur The network computer platform 10 of machine state resumes normal operating state again.

In a word, the present invention provides a novel method and system for remote rebooting of a network computer platform, which can be applied to a network system, so that the network system administrators can use it when any computer platform connected to the network system is down. and reactivating the downtime computer platform by remote control, so as to restore the downtime computer platform to a normal operation state. Compared with the prior art, because the present invention only makes different settings for existing hardware and software facilities and adds a new SMI processing program (i.e. the above-mentioned SMI signal checking module 140) in the BIOS during actual implementation, no need Adding other software and hardware facilities can provide a remote restart function in case of downtime. Therefore, the present invention has better progress and practicability than the prior art.
