Fig. 1 represents that personal computer and operating system thereof that a kind of reliability of the present invention is high are divided into a kind of diagram of different module stores to different memory locations to operating system.
As shown in the figure: BIOS, the basic kernel of operating system and mainboard drive and are saved in the nonvolatile memory of installing on the mainboard, the driver of the integrated circuit board of installing on the computing machine is saved in the nonvolatile memory of installing on the corresponding integrated circuit board, the driver of computer peripheral equipment is saved in the nonvolatile memory of installing on the peripheral hardware, and the system's register information and the application data of computer application program and application program are saved on the hard disk as file.
Present embodiment uses LINUX operating system as original shape, because its source code is open, based on the GNU plan, therefore can reduce arbitrarily.Present embodiment to LINUX operating system reduce LINUX operating system with device drives all reduce, compile out a not kernel of carrying device driving, it is basic kernel, greatly about three or four hundred K, can be loaded in the nonvolatile memory fully, and but device drives is as the kernel module of dynamic load, stores in the nonvolatile memory on the integrated circuit board at corresponding device place.
Present embodiment increases by two suitably non-volatile FLASH storeies of size on the mainboard of computer, the FLASH storer of a 512K byte is used for storing the kernel of reducing out, the FLASH storer of another 128K byte is used for storing the mainboard driver, and these two FLASH storeies take the ISA address space of 640K byte-sized altogether; This ISA address space can be positioned at the ISA address space of 14M-16M, can also be put into the ISA address space that is lower than 1M to the FLASH storer of the 128K byte of storage mainboard driver, take the ISA address space from 0xE0000 to 0X100000, reuse with the address space of system bios, but can be distinguished by the A20 signal wire, the FLASH storer of the 512K byte of the kernel that another sheet storage is reduced out is put into the ISA address space of 14M-16M; Present embodiment uses the second way, and as shown in Figure 2, BIOS and mainboard drive and be in the ISA address space that is lower than 1M, and the two address is public, and the basic kernel of operating system is in the ISA address space of 14M-16M; Figure 3 shows that saved system BIOS on the mainboard; the logic diagram of circuit of three FLASH storeies of mainboard driving and the basic kernel program of operating system; wherein U2 is the FLASH storer of the basic kernel of storage operating system; be in the ISA address space of 14M-16M; U3 is the non-volatile FLASH storer of storage mainboard driver; U4 is the non-volatile FLASH storer of storage system BIOS; and use A20 and a not gate U1 to be used as U3; the chip selection logic of U4; when A20 does not open; choose U4; when A20 opens; choose U3; therefore the two can public 0xE0000 to the ISA address space of 0X100000; U2; U3; U4 receives on the identical isa bus; the three uses the memory addressing mode to visit; their read signal is public; and write signal is controlled by a soft switch or a hard switching: U2 is subjected to soft switch SW 2 controls with imitating signal; U3 is subjected to a hard switching K1 (wire jumper) control with imitating signal; U4 is subjected to soft switch SW 1 control with imitating signal; they are in read-only protected mode usually, use soft switch or hard switching can make it be in WriteMode when upgrading.
Because computing machine is in real pattern when start, the address that can visit has only 1M, therefore by modernization system BIOS original code from disk or CD pilot operationp system is removed, increase the code of one section pilot operationp system from nonvolatile memory, the major function of this section is certain clear position that the program that the previous section that is placed into the basic kernel of operating system of 14M-16M ISA address space calls SETUP is moved on to 640K before the internal memory, as the 0X10000 place, and jump to this section code and carry out; The SETUP program is after detecting and obtain hardware information and detecting the drive information of installing, the SETUP program switches to protected mode to computer patterns, and open the A20 function, then jump to the other parts that are placed into basic kernel in the high-end FLASH storer of ISA and begin to carry out, the program of SETUP program back in the promptly basic kernel; Because the real map of basic kernel is generally through overcompression, so the gunzip normally of the program after the SETUP program, this gunzip is decompressed to 0X100000 place to the real map of basic kernel and begins execution; In basic kernel start-up course or afterwards, by reading the mainboard driver of 0xE0000 to the ISA address space of 0X100000, finish the initialization of mainboard and drive loading tasks, also to the hardware drive program in the nonvolatile memory on other integrated circuit board of installing in the detected system also be loaded in the system, finish the startup of kernel; Follow the file system of installing according to kernel, read the kernel file system can discern on the hard disk application program and application data, can be for application program by the mount message of application program is saved in certain register-file, and be saved in certain fixing catalogue on the hard disk, root directory as first subregion of hard disk, operating system is come the operable application program of register system according to the mount message in this register-file, thereby finishes the initiating task of total system.
The basic kernel of the operating system of the personal computer of this embodiment and each hardware driving just are cured in the FLASH storer in the time of can dispatching from the factory, but can use a ROMPaq that they are upgraded when needed, the ROMPaq of embodiment is as a module of operating system itself, when starting, if press certain function key, as the F10 key, then enter ROMPaq, this ROMPaq has four functions, 1, upgrading master routine, 2, certain driver of upgrading, 3, back up basic kernel, 4, recover basic kernel.
When the upgrading driver, upgrade step is:
At first open will the upgrade WriteMode hard switching of nonvolatile memory of driver of preservation, and read in upgrade file, in the CMOS of computer information, search then and the corresponding to device drives information of upgrade file, if find then carry out the upgrade job of device drives.
If in the CMOS of computer, can not find device drives information, then carry out the detection of hardware, search and whether be equipped with in the system and the corresponding to device drives of upgrade file, find corresponding to device drives, then carry out the upgrade job of device drives.
This example is by being the globally unique equipment class model of a unification of every class driver distribution, and carry out consistency desired result in conjunction with the producer and the version information of driver, just permit driver upgrade when having only equipment class model and producer's type and the version of driver all consistent.
When the upgrading master routine, upgrade step is:
At first use soft switch SW 2 to open the WriteMode of the nonvolatile memory U2 that preserves the basic kernel of operating system, restart the upgrading installation procedure, select upgrading or basic kernel program is installed, and read in basic kernel file, then basic kernel file is deposited among the nonvolatile memory U2 on the mainboard of preserving the basic kernel of operating system, restart machine, just finish the upgrading or the installation task of basic kernel.
