Step 1, the first system and second system using domestic operating system and android respectively as dual system, and
It is respectively stored on solid-state disk and embedded multi-media card, and subregion as follows：
Solid-state disk is divided into operating system area, the first system is directly installed on operating system partition；
By embedded multi-media card be divided into firmware area, systematic parameter area, boot subregions, inner core region, resource-area, system area and
User data area, the storage of firmware area upper electric treatment device, internal memory and peripheral hardware setup code；Deposit this Nand in systematic parameter area
Flash partition parameter information；Kernel, device tree and the startup Logo of boot subregions storage second system；Inner core region storage first
The kernel of system；The device tree and startup Logo of resource-area storage the first system；System area deposits the data of second system；User
The application of data field storage user installation and data；
Step 2, according to following flow startup dual system：
1) firmware area code is performed on after electricity, initialization processor, internal memory, basic input and output these hardware devices, is built
Vertical running environment；
2) partition size in systematic parameter area, initial address these parameter informations are read；
3) detect whether to insert USB Key and verify, enter if being verified 6), otherwise into 4)；
4) boot subregions are read, the kernel of second system, device tree these resources are loaded into internal memory；
5) construction passes to the kernel parameter of second system, performs kernel, carry system area and user data area, completes the
Two system starts；
6) dual system selection interface is exported to screen, waits user to select to need the system that starts, if user is when default
Interior non-selected then acquiescence selection starts the first system；
7) if user selects the first system, into 8), otherwise it is transferred to 4)；
8) from inner core region loading the first system kernel, from resource-area loading the first system device tree, start Logo this
A little resources are to internal memory, and dynamic construction needs to pass to the kernel parameter of kernel；
9) kernel is run, according to the operating system on kernel parameter carry solid-state disk, completes the startup of the first system.
(3) beneficial effect
The present invention devises for domestic tablet device supports the dual system of domestic operating system to store and start method, full
The autonomous controllable system requirement of foot；Verified by USB key, high safety grade system is transparent to lower security class user；By double systems
System is stored in distinct interface storage device, meets different application scene to memory capacity and the different demands of access speed.Should
Method makes dual system physical isolation, and the application software that Android system can be utilized to enrich, and can is selected according to user security grade
The autonomous controllable domestic operating system using storage significant data is selected, ensures information high safety；By using distinct interface
Storage device, meet that system is required memory capacity and the different of readwrite performance.
