Abstract

A computer system and a remote control method thereof are provided. The method is adapted for the computer system having a network and a processor. In the method, the network card is used to receive a management interface request sent by a remote device thorough a network and send a system management interrupt to the processor, so as to wake up the processor and control the processor to enter a system management mode. Then, the processor loads a management monitoring program into a memory so as to execute the management monitor program. Finally, the processor processes the management interface request by using the management monitoring program in the system management mode, and replies a processing result to the remote device through the network by using the network card.

Claims

1. A remote control method of a computer system, adapted to a computer system having a network card and a processor, comprising:

receiving a management interface request sent by a remote device via a network by using the network card;

sending a system management interrupt to the processor to wake up the processor and control the processor to enter a system management mode;

the processor loading a management monitoring program into a memory to execute the management monitoring program; and

the processor processing the management interface request in the system management mode by using the management monitoring program, and replying a processing result to the remote device via the network by using the network card, wherein

after the step of receiving the management interface request sent by the remote device via the network by using the network card, the method further comprises;

storing the management interface request in a temporary storage device in the network card;

the step of sending the system management interrupt to the processor to wake up the processor and control the processor to enter the system management mode comprises;

regularly sending the system management interrupt to the processor to wake up the processor by using a timer;

after the step of sending the system management interrupt to the processor to wake up the processor and control the processor to enter the system management mode, the method further comprises;

the processor checking whether the management interface request is stored in the temporary storage device of the network card;

the processor loading the management monitoring program into the memory to execute the management monitoring program when it is determined that the management interface request is stored in the temporary storage device; and

the processor processing the management interface request in the system management mode by using the management monitoring program, and replying the processing result to the remote device via the network by using the network card.

2. The remote control method according to claim 1, wherein the network card supports a Wake-on-LAN (WOL) function, and the step of sending the system management interrupt to the processor to wake up the processor and control the processor to enter the system management mode comprises:

the network card sending the system management interrupt to the processor to wake up the processor according to the received management interface request and control the processor to enter the system management mode.

3. The remote control method according to claim 1, wherein the step of checking whether the management interface request is stored in the temporary storage device of the network card further comprises:

controlling the processor to enter a power saving mode and reseting the timer when it is determined that the management interface request is not stored in the temporary storage device.

4. The remote control method according to claim 1, wherein after the processor processes the management interface request in the system management mode by using the management monitoring program, and replies the processing result to the remote device via the network by using the network card, the method further comprises:

controlling the processor to enter a power saving mode and reseting the timer.

5. The remote control method according to claim 1, wherein after the processor process the management interface request in the system management mode by using the management monitoring program, and replies the processing result to the remote device via the network by using the network card, the method further comprises:

controlling the processor to enter a power saving mode.

6. A computer system, comprising:

a network card comprising a temporary storage device, connected to a remote device via a network and configured to receive a management interface request sent by the remote device and store the management interface request in the temporary storage device;

a memory;

a processor, connected to the network card and the memory, and configured to wake up from a power saving mode and enter a system management mode when receiving a system management interrupt; and

a timer, connected to the processor and configured to regularly send the system management interrupt to the processor to wake up the processor, wherein

the processor loads a management monitoring program into a memory to execute the management monitoring program when being woken up, and processes the management interface request received by the network card in the system management mode by using the management monitoring program, and replies a processing result to the remote device via the network by using the network card, and

the processor checks whether the management interface request is stored in the temporary storage device of the network card when being woken up, loads the management monitoring program into the memory to execute the management monitoring program when it is determined that the management interface request is stored in the temporary storage device, and processes the management interface request by using the management monitoring program.

7. The computer system according to claim 6, wherein the network card supports a Wake-on-LAN (WOL) function, and further sends the system management interrupt to the processor to wake up the processor and control the processor to enter the system management mode when receiving the management interface request.

8. The computer system according to claim 6, wherein the processor further enters a power saving mode when it is determined that the management interface request is not stored in the temporary storage device.

9. The computer system according to claim 6, wherein the processor enters a power saving mode and resets the timer after replying the processing result to the remote device via the network by using the network card.

10. The computer system according to claim 6, wherein the processor further enters a power saving mode after replying the processing result to the remote device via the network by using the network card.
