Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Referring to Fig. 1, the invention provides a kind of computer platform with multiple operating system, this computer platform 100 has host side 10, memory device 20 and hard disk 30, wherein: memory device 20 has a plurality of independently physical blocks, and a plurality of logical blocks of described a plurality of physical blocks reflection, corresponding, an each described physical blocks LBA (Logical Block Addressing corresponding to the logical blocks of its reflection, LBA (Logical Block Addressing)) system, hard disk 30 can be mechanical hard disk or solid state hard disc.Need to prove, the memory device 20 described in the present embodiment, it can be comprised of a plurality of independently memory bars, and each memory bar is namely an independently physical blocks.
For storage device of the present invention (hard disk 30), it is to should there be a plurality of LBA system, and the LBA number of systems is identical with the number of the physical blocks of memory device 20, and separate.Simultaneously, for the computer platform 100 of multiple operating system provided by the invention, its each operating system is a corresponding LBA system independently.
Referring to Fig. 2, the invention provides a kind of changing method of multiple operating system again, they can be by computer platform shown in Figure 1 100 realizations, and the method comprises:
Step S201 sets up the related information table of described a plurality of operating system and LBA (Logical Block Addressing) system.Previous embodiment illustrates, each operating system corresponding LBA system by setting up the related information table of operating system and LBA system, can make host side 10 obtain easily operating system corresponding to LBA system.
Step S202, receive current operation system is switched to the instruction of destination OS after, according to the described related information table described current operation system of inquiry and LBA system corresponding to destination OS.Concrete, when computer platform 100 receives when switching to the order of the second operating system from the first operating system, it is inquiry two the LBA systems that operating system is corresponding, then execution in step S203 from the related information table at first.
Step S203, LBA (Logical Block Addressing) that described current operation system is corresponding system switch to LBA (Logical Block Addressing) system corresponding to described destination OS.Suppose that current operation system is the first operating system, destination OS is the second operating system, and computer platform 100 can switch to a current LBA system the 2nd LBA system of target.This moment, 100 of computer platforms were enabled the physical blocks of memory device 20 corresponding to the 2nd LBA system, and other physical blocks of memory device 20 will be in unactivated state.
Further, above-mentioned steps S203 specifically comprises:
Step S2031 stores a marker bit, with the current switching state of mark.Computer platform 100 is at marker bit of Embedded Controller the inside storage, and the mark current event is switched system.
Step S2032 carries out standby operation with described current operation system, and sends the switching wait command of LBA (Logical Block Addressing) system.Concrete, current operation system is carried out suspend to memory(equipment enter sleep state, but all data also are kept in corresponding memory block, only have some external interrupt just can wake-up device) standby operation, the physical blocks of the memory device 20 that current operation system is corresponding is arranged on unactivated state, but the maintenance data, the instruction that sends simultaneously switch LBA pending (switch and wait for) is given to hard disk 30.30 receive this instruction after, can with the instruction temporary respite of switch LBA, just carry out when waiting until next electrifying startup.
Step S2033 reads described marker bit, and the physical blocks of the memory device that described current operation system is corresponding is carried out the dormancy processing, and the physical blocks of the memory device that described destination OS is corresponding activates processing.Complete the operation of suspend to memory at computer platform 100 after, auxiliary logical block (can be Embedded Controller) removes to read marker bit, to obtain current status information, and the physical blocks of the memory device 20 that current operation system is corresponding is carried out inactive processing (standby) as requested, the physical blocks of the memory device 20 that destination OS is corresponding activates processing (waking up) simultaneously, realizes whereby the switching of internal memory.
After the internal memory of computer platform 100 switches, EC controls and restarts, computer platform 100 after startup has the physical blocks of memory device corresponding to destination OS 20 and the 2nd LBA system in corresponding hard disk 30 with it, whereby, destination OS can start in the 2nd LBA system, and all service datas all can operate in the thing 20 reason blocks of memory device corresponding to described destination OS in service.If the user continues switched system, repeat above-mentioned flow process.
in sum, the present invention is by presetting the memory device with a plurality of physical blocks, and each physical blocks reflection has a plurality of logical blocks, each described physical blocks LBA (Logical Block Addressing) system corresponding to the logical blocks of its reflection, computer platform can be set up the related information table of its a plurality of operating systems and LBA (Logical Block Addressing) system, and after receiving the instruction that current operation system is switched to destination OS, inquire about respectively described current operation system and LBA (Logical Block Addressing) system corresponding to destination OS according to described related information table, and LBA (Logical Block Addressing) that described current operation system is corresponding system switches to LBA (Logical Block Addressing) system corresponding to described destination OS, switching between the complete operation system easily whereby.
Certainly; the present invention also can have other various embodiments; in the situation that do not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
