Describe the present invention in conjunction with exemplary embodiment with reference to the accompanying drawings.
Embodiment 1:
As shown in Figure 1, the secondary main board system of computing machine comprises USB HUB and the large core component of main control module two, it is connected with computer platform by USB interface, in the present embodiment, a USB interface expands to 4 (are generally 4 but are not limited to 4) by USB HUB, wherein USB port 1 is connected with main control module, the hardware logic of usb bus interface between the adaptive native system of USB HUB and computer motherboard.Wherein USB port 2 connects USB flash disk equipment, and USB port 3 connects portable hard drive equipment, and USB port 4 connects other USB device.Such as need can connect printer when printing, need also can, in independent connection, need online to connect USB network card etc. during other memory device external.
Wherein, be provided with embedded OS in USB flash disk equipment or portable hard drive equipment, the recent systems win8 due to Microsoft's development supports the use of all kinds of terminal device, surveys the system that win8 system can be used to use as secondary mainboard device through applicant.Main control module comprises CPU: the soft and hardware being responsible for native system controls; ROM firmware: the software program storing main control module, comprises and the usb communication module of mainboard, FLASH module for reading and writing, HUB port control modules; RAM: the temporary storage location of software program operational data; FLASH: preserve application program, user data and file; HUB port control logic: opening and disconnection of control USB HUB port.In the present embodiment, the power supply of the secondary mainboard of described computing machine is input as+5 volts.
In USB HUB described in this programme, USB is the abbreviation of English Universal Serial Bus, and Chinese is exactly " USB (universal serial bus) ", also claims general series interface.Hub is the hub that the large daily life of a family is said, it uses stelliform connection topology configuration to connect multiple USB interface equipment.Usually, USB Hub can connect computer desk lamp, computer fan, MP3, USB flash disk, recording pen, digital camera etc.A USB interface can be extended to multiple USB interface worked alone, each power supply is up to 500MA.It possesses following advantage:
Directly be connected with computer, need not external power supply, simply handy;
Computer identifies installation automatically, need not driver, plug and play, plug
Speed up to 480Mbps, backward compatible USB1.1;
Built-in current overload short circuit protective device
System is supported: Win95/98/Me/2000/XP, Linux2.4andMac os8.5 or more version.
BIOS:BIOS setting program described in the present embodiment is stored in BIOS chip, and BIOS chip is mainboard lastblock rectangle or square chips, only just can arrange when starting shooting.(generally enter BIOS when computer starting by F2 or Delete to arrange, some special types are arranged by F1, Esc, F12 etc.).BIOS setup program mainly manages the Basic Input or Output System (BIOS) of computing machine and arranges, and makes system cloud gray model under best condition, uses all right removal system fault of BIOS setup program or diagnostic system problem.Since someone thinks that BIOS is " program ", it should be just belong to software, feels just as oneself conventional Word or Excel.But also have a lot of people so not think, because it and general software still have some to distinguish, and it and contacting of hardware are also considerably tight.Figuratively, BIOS should be one " bridge " connecting software program and hardware device, is responsible for the instant requirement solving hardware.BIOS chip on mainboard is perhaps unique labeled chip on mainboard, and generally it is the integrated circuit of the dual inline type of one piece of 32 pin, is printed on " BIOS " printed words above.
In the present embodiment, by the hardware device of active computer platform as display, internal memory, keyboard, mouse, the hard disk of computer equipment, network interface card are isolated the safety that ensure that Card read/write, low being convenient to of the little cost of volume is carried with and a large amount of suitability for industrialized production simultaneously, be connected with computer motherboard by USB interface, system firmware obtain mainboard BIOS operation power redirect after, the hardware resource configuration data of adapter mainboard BIOS; When user selects to guide operating system from the external portable hard drive of native system or high capacity U disc, then open the USB port that native system HUB is all, and the mainboard device (as hard disk, network interface card, other USB port etc.) that will forbid is selected according to user, change the hardware resource configuration data of mainboard BIOS, remove corresponding device controller from the system bus of mainboard, operation power is jumped to the external portable hard drive of native system or high capacity U disc guiding operating system.
It achieves and carries hard disk or the physical isolation of data message between high capacity U disc and computer motherboard hard disk, is especially applicable to being applied to notebook/integrated computer.When native system is connected to network A by circumscribed USB network interface card or networking-on-motherboard card and mainboard is connected to network B by network interface card; then achieve the physical isolation of data message between A, B two networks; effectively prevent the leakage of internal network data message; protect the safety of internal network data message, the physical isolation between the inside and outside network information in the computer internet data transmission of industry-by-industry can be widely used in.
Embodiment 2:
As shown in Figure 2, partition method comprises:
The secondary mainboard of step a. computing machine is connected with computer platform by USB interface;
After step b. computer platform powers on, described computer platform display device display startupoptions, described startupoptions comprises the startup of computer platform local hard drive, the secondary mainboard of computing machine starts;
If step c seletion calculation machine platform local hard drive starts, then programming jump loads to local hard drive completion system, if the secondary mainboard of seletion calculation machine starts, then programming jump loads to the USB flash disk be connected with the secondary mainboard of computing machine and/or portable hard drive completion system.
