Embodiment
In order to make purpose of the present invention, technical scheme and advantage are clearer, and by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
Because the implementation of BIOS or operating system all is serial, the data message between BIOS and the operating system is not shared, and will repeat the detection of identical hard disk, has wasted the time that computer starting or multiple operating system switch.Therefore, in RAM, build a data list, realize the data information sharing between BIOS and the operating system, below illustrate the data form among the RAM, as shown in table 1, the part that table 1 is begun by the F000 section for data form:
| Data form (F000 section) | ||
| Location address | Length | Parameter |
| 0H | ' BIOS table ' | Banner string. |
| 0AH | 1 | 。。。 |
| 0BH | 1 | 。。。 |
| 0CH | 1 | 。。。 |
| 0DH | 2 | 。。。 |
| 。。。 | 。。。 | |
Table 1
Data form is by location address, and length and parameter are formed, and when the reference position address is F000H, begins to store the BIOS table, and promptly BIOS table indicates various character string types.Various data messages in the BIOS table are stored in the data form successively by location address.
When computing machine when starting, the data message that detects hard disk deposits in respectively on the diverse location address in this data form; When computing machine carries out multioperation and switches, not only deposit the data message that detects hard disk in this data form in, and deposit switch data information in, i.e. the sign of Qie Huaning, these data messages also deposit in respectively on the diverse location address in the data form.
By the data form among the RAM, it is mutual just can to carry out data message between BIOS and the operating system, as shown in Figure 3, Fig. 3 is the synoptic diagram of exchange channels between BIOS and the operating system, data message between BIOS400 and the operating system 402 is undertaken alternately by the data form among the RAM 401, realize the data information sharing of BIOS and operating system, reaching a certain operation to computing machine does not need the purpose that repeats.
As shown in Figure 4, Fig. 4 is a computer starting process flow diagram flow chart of the present invention.When computer starting, the step of its start-up course is:
Step 400,401, the computing machine electrifying startup;
Step 405,406, the booting operating system program start, os starting finishes.
BIOS carries out initialization to CPU and when hardware device detected, the data message of detection hardware equipment is filled in the data form, operating system does not then need hardware device is directly detected in start-up course, only needs the data message in the inquiry form just can start the operating system.
For BIOS being described after having detected some fixing hardware devices, operating system does not need identical hardware device to be detected again again, for two example two.Example one: if computing machine is equipped with the ROM (read-only memory) (DVD-ROM) of Digital video disc, the process that BIOS detects DVD-ROM and detects its integrated device electronics (IDE) interface on mainboard is: BIOS detects first passage Primary Hard Drive (IDE Primary Master) interface in order successively, second channel Primary Hard Drive (IDESecondary Master) interface, first passage from hard disk (IDE Primary Slave) interface and second channel from hard disk (IDE Secondary Slave) interface, which interface the storer of judging which kind of type is present on, if being DVD-ROM, testing result is present on the IDE Primary Master Interface, then testing result is stored in the data form of RAM, when operating system during at detection hardware equipment, the data message that operating system is only called in the RAM data form is learnt the position of DVD-ROM, and need not detect actual hardware device.Example two: when the interface to mouse detects, if the result that BIOS detects is USB (universal serial bus) (USB) interface, then with this data information memory in the data form of RAM, operating system is skipped the detection to mouse interface, directly from the data form of RAM, extract data message, the interface type of mouse is set.
When the multiple operating system of computing machine switches, use the data form among the RAM to realize that the data message between BIOS and the operating system is mutual equally, at this moment in data form, not only deposit in and detect hard disc data information, and deposit switch data information in.As shown in Figure 5, Fig. 5 is a multiple operation systems of computer handoff procedure process flow diagram of the present invention, supposes that two operating systems are respectively OS-1 operating system, OS-2 operating system, and implementation step is:
Step 500,501 according to computer starting flow process of the present invention, makes the OS-1 os starting;
Step 502,503, send the computer operating system switching command, OS-1 operating system is with switch data information, be that the switching mark position is stored in the data form that contains the hardware device data message and this switching mark position of set, the perhaps zone bit that set has set in advance in complementary metal oxide semiconductor (CMOS) (CMOS);
Step 504,505, BIOS by CMOS zone bit or the zone bit in the data form whether set judges whether OS-1 operating system closes fully, if zone bit set, then operating system is closed, and changes step 507 over to; Otherwise, change step 506 over to;
Step 507,508,509,510, the hard disk that BIOS directly calls in the data form detects data message, judges that OS-2 operating system copies on the RAM in the position on the hard disk and OS-2 operating system, the hardware device that OS-2 operating system is directly called in the data form once more detects data message, finish the startup of OS-2 operating system, make OS-2 operating system operate as normal, finish the handoff procedure of computer operating system.
The changing method of computer starting provided by the invention and multiple operating system has shortened the start-up time of computing machine and the switching time of multiple operating system.
Unit: second
| Pattern | A | B |
| BIOS | 12 | 12 |
| LINUX | 30 | 10 |
| The overall time | 42 | 22 |
Table 2
When computing machine started, as shown in table 2, table 2 was the former start-up time of computing machine and the comparison sheet of start-up time of the present invention.It is LINUX operating system original computer os starting process that Mode A is set, the start-up course of Mode B for computing machine of the present invention is set, just between BIOS and operating system, carry out the start-up course of the mutual computing machine of data message by the data form of RAM, all be 12 seconds BIOS working time of Mode A and Mode B, but LINUX operating system is 10 seconds in the working time of Mode B, and it is 30 seconds in the working time of Mode A, therefore, adopt method of the present invention to make the overall time of startup of computer operating system drop to present 22 seconds, shortened the start-up time of computer operating system greatly by original 42 seconds.
When computer operating system is switched,, also shortened the time that computer operating system is switched greatly owing to having skipped BIOS and operating system to the hard disk duplicate detection time.
The above only is preferred embodiment of the present invention, in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is not equal to replacement, improvement etc., all should be included within protection scope of the present invention.
