Abstract
The invention relates to the field of operating systems, and discloses a system disk switching method and device for a linux operating system. A boot loader is programmed to a flash, two system disks with the linux operating system are manufactured, one system disk is optionally selected and set as a current system disk, and the other system disk is set as a standby system disk; after the system is powered on, the boot loader is started from the flash, the boot loader searches for the current system disk, if the current system disk is found, whether data of the current system disk are integral is detected, if the data are integral, the system is started from the current system disk, and otherwise the boot loader searches for the standby system disk; if the standby system disk is found, whether data of the standby system disk are integral is detected, if the data are integral, when the current system disk breaks down and other problems occur, the current system disk can be switched to the standby system disk, and the system can be started from the standby system disk.
Description
Technical field
The present invention relates to operating system field, relate in particular to a kind of system disk changing method and device of linux operating system.
Background technology
Along with the development of various hardware resources, the ability of electronic equipment is also more and more stronger.The also appearance in a large number of product of two operating systems is installed for this reason, on an electronic equipment platform.Two operating systems of conventionally, installing on an equipment operate in respectively in region of memory separately.During the first operating system, the second operating system is in dormant state.When switching, make the first operating system enter dormant state, then wake the second operating system up.Profit realizes the switching of two operating systems in such a way.But if the operating system of moving collapse, system cannot normally enter the state that suspends to internal memory, thereby also cannot normally switch between dual system.
At present, under embedded Linux operating system environment, also there are not system disk changing method and device.
Therefore, expectation provides a kind of system disk changing method and device of linux operating system, can occur at the system disk of linux operating system when abnormal automatically switching to another system disk, thereby realize system disk, switches.
Summary of the invention
Technical matters to be solved by this invention is: a kind of system disk changing method and device of linux operating system are provided, can realize when current system dish breaks down, can be switched to back-up system dish, from back-up system disk startup system.
