Problems solved by technology

[0008] But above-mentioned two kinds of methods have deficiencies again, the shortcoming of the first kind of method is: can only realize the safe recovery of computer operating system locally, can't realize the function of remote recovery; The shortcoming of the second kind of method is: through remote monitoring management can Realize the shutdown and restart of the computer system, but cannot solve the failure of the operating system crash, and cannot remotely install the operating system

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] With reference to Fig. 2, computer system of the present invention comprises: BIOS (basic input output system) chip, nonvolatile memory NVSRAM chip, network card and BMC control chip or remote management card (with BMC control chip), wherein, BMC control chip Including the F / W module, the BIOS chip, the NVSRAM chip and the BMC control chip or the remote management card can all be located on the computer motherboard. The BMC control chip and the network card are powered by a 5-volt standard power supply, and the BMC control chip communicates with the remote control unit through the network card.

[0034] The NVSRAM chip is specially designed for the mainboard of the computer, and is used for storing the second operating system code of the cut microkernel; the BIOS can access the microcode in the NVSRAM chip through the system bus. The BIOS chip, the NVSRAM chip ...

Abstract

The invention relates to a computer remote control method and a computer system, wherein a remote communication module is employed to communicate, and a starting bit zone of a bit zone loading module is changed and a restart / or start command is sent to the computer; the starting bit zone is checked by a basic input and output system, if the starting bit zone is set as a bit zone for starting the second operation system, then the second operation system in a storage apparatus will be started; then the computer can be operated by a running second operation system. Said remote communication module is a BMC chip, said bit zone storage module is a F / W module of the BMC chip; and said storage apparatus is a nonvolatile memory NVSRAM. By using the scheme, a remote complete control can be implemented, the remote diagnosis and network function of the second operation system can restore and re-install the operation system and repair the operation system malfunctions apart from the physical damage of the motherboard.

Description

technical field [0001] The invention relates to a computer remote control method and system, in particular to a method and system for remotely restoring a computer operating system through a monitoring system. Background technique [0002] Computer equipment such as servers need to run continuously for a long time, and at the same time, remote monitoring management and fault recovery are required in order to solve various problems that occur during the operation of the computer system in a timely manner. Among them, the operating system failure of the computer system is a large category of typical computer failures. Once the computer operating system fails and cannot continue to run, the system will appear in a blue screen or crash state. Moreover, the problem cannot be solved by shutting down and restarting the system, and can only be run again by reinstalling and restoring the computer operating system. [0003] For the failure of the computer operating system, the existi...
