Abstract

An embodiment of the invention discloses a method, a device, a chip and a computer mainboard for isolating and switching internal and external network and a computer. The method includes that commands switched from a first operation system to a second operation system are received and electrically started on the first operation system to be initialized through a first code of a BIOS (basic input / output system) and matched with a first memory storage area; the first operation system is controlled to be power off to idle according to the commands, CPU (central processing unit) reset is performed by adopting a second code of the BIOS, a second memory storage area is initialized, and matching is performed on the second memory storage area and the second operation system; the second operation system is issued to wake up the commands for electric starting. On the premise of not developing a new mainboard, the internal and external network operation systems of an electronic device are switched, so that cost of mainboard manufacturing of the electronic device is saved.

Description

technical field [0001] The invention relates to the technical field of computer main boards, and more specifically relates to a method, a device, a chip, a computer main board and a computer for isolating and switching between internal and external networks. Background technique [0002] The internal and external network isolation technology refers to the technology that the external network cannot invade the internal network, and at the same time prevents internal network information from leaking to the external network. [0003] The existing internal and external network isolation technology realizes the separation of internal and external memory networks by modifying the circuit of the computer motherboard, that is, setting memory modules on the same computer for the internal network and external network respectively, so as to achieve the purpose of isolating information. [0004] However, the above-mentioned internal and external network isolation technology needs to red...
