Description of the invention: [Technical field to which the invention pertains] The present invention relates to a computer, and more particularly to a computer using an interrupt instruction of a basic wheel-in system, first reading a protection description data set in the hard disk, and then According to the protection description data, it is decided to continue to complete the method of starting the operating system. [Prior Art] Know: 'Electric fine (such as desktop computer, notebook computer or servo machine, etc.) usually install at least one hard disk machine (Hard Disk), each hard disk machine has a main starting magnetic Zone (the computer industry regulations are stored in the hard disk drive's zero cylinder (cylinder 0), the zeroth head (Head 〇), the first magnetic zone (Sect〇r 1), which is the front magnetic zone of the hard disk drive ), a master boot record (MBR) is stored in the main boot magnetic area. The main boot record includes a jump area (Jump Area) which is specified to read the boot code area of the hard disk drive, and one boot code area (Boot c〇de) to store the boot code area (MBR Boot Code Area). ), storing a partition partition table area (Partition Table Area) of each disk partition table, and as an end region for identifying the end of the main boot magnetic region (which is AA 55 with two bytes) Share. When the hard disk drive is set to start an operating system (Operation System - Master Hard Disk), the action of starting the operating system is completed according to the contents of the main boot record, so that the computer can The data is stored in the hard disk drive. However, the cases of computer theft are endless. For many computer users, the loss caused by the computer is often not the price of the computer itself -5 - 200825743, but the hard disk drive. The confidential or private important information of the user may have been 'especially the computer of the company's line number. If it is stolen, if the information in the hard disk of the person (4) is transferred to the competitor, it is a big problem. In view of the above problems, the industry has developed a (four) method of hard disk drive, using bribes to protect the face towel (4), to avoid the occurrence of data outflow. The above data protection method is based on a password. Protection program (such as: Microsoft user (10) user password: After the computer starts the operating system, then the password protection program is required to require the user to enter the password. After that, when the password protection program receives the correct ^ code of the J, it will allow the maker to log in to the system, and then use it as the ", first solution, 4 code * type" to access the data in the hard disk drive. If the 2 code protection program is not connected to the _ positive password, the system will not be able to log in to the operating system, nor can it access the data of the _, and the data in the hard disk will be protected. And if the thief directly puts the (four) machine into another computer, the thief only needs to use another hard disk drive of another computer, and then use the other machine; after the health system, the recovery tool or the hacking tool intrusion = take In the hard disk drive, and access to the hard disk drive of the stolen computer, access to the hard disk drive of the stolen computer is not the same as any important information of the 2 hard disk drive. The stolen person will be arbitrarily accessed, and Lu's current hard disk drive does not have a long-term protection for the tilt. In view of the fact that the hard disk drive data is still in the outer place, the inventor has worked hard for research and experimentation for a long time in 200825743. The method of setting up the information of the machine. The 'Weng's supply-face protection data=, the method is the computer at the stage of self-test, & machine has been added to protect the description, and U see hard disk description package self-identification stone horse and protection When the content of the special part of the drawing is consistent, the disk of the hard disk machine has a disk partitioning table for the Ray Brain #^, ° computer to complete the self-test, then make, complete, and complete the booting system The processing, and the hard specific ^ = ° and the electric power of the object 1 _ the contents of the data does not match, the disk partition of the hard disk machine is cleared, the brain can not read the miscellaneous and difficult Immediately after Lee's processing, 'compensation made the computer not only unable to complete the boot-up process' but also could not access the data on the hard disk drive, which was far from protecting the data of the hard disk drive. In order to make the characteristics of the invention and its Wei, to make a step by step of understanding and understanding, _ real_ with the schema, the detailed description is as follows: [Embodiment] The present invention is a kind of information for protecting the hard disk drive. The method is applied in the first picture of (4), #电脑 is performing the basic output input system, the self-峨P group, after the initialization of the memory, and at the beginning of all the hard disk After recording Wei Xing, it will be processed according to the following steps. ((8) Beer q basic output wheeled into the system interrupt command, in order to read the 200825743 hard disk machine; (11) to determine whether there is any hard disk drive Has not been confirmed, if yes, proceed to step (12), otherwise, proceed to step (15); 〇 2) read one of the hard disk drives that have not been confirmed, and determine whether there is a protection description data in the hard disk drive 4 If yes, proceed to step (13), otherwise, perform step (9); in one embodiment of the present invention, (4) shown in item 2, the data structure of the protection description material 4 includes an identification mark area 40, a hard Disc identification code storage area 42, a backup disk partition table Storage area 44 and - check sum code storage area 46. The information stored in the identification area 40 is used to indicate the identification information of the data 4 in the hard disk drive. The hard disk identification code storage area 42 stores a hard disk identification code. The hard disk identification code is the same as the computer identification code of the computer that needs to be protected by the hard disk drive, and the computer identification can be a universal unique identification code (Universal toique Identificatic), for example, a system management. The basic input round-out system (SMBI0S; System Management BI0S) job 1 (Type υ Universal Unique Identification Number (10) ID) block value, in other words, the hard disk identification code is also a universal unique identification code. Backup disk partition table storage area 44 _ with the library backup disk partition, (four) copies of the contents of the partition table, and the disk partition table of the master boot record of the hard disk drive ♦ when the hard disk drive needs to be protected The contents of all the disk partition tables stored in area 5 (as shown in Figure 7 or Figure 8) are the same. Check code storage-8- 200825743 Storage area 46 stores the value of the protection description data 4 after being checked by the inspection program; ((8) Judging whether the protection description data 4 has a part matching the computer identification code set by the computer, If yes, proceed to step (10), otherwise, the ordering step (16); in this embodiment, determining the protection description, whether the data 4 has a knife corresponding to the _ computer identification code set by _, that is, reading the hard disk identification The code storage area must be = hard disk identification code, and judge whether the hard disk identification code is the same as the computer identification code. The hard disk identification code and the computer hard work code are universal only-identification codes, and the hard disk code is The computer identification code of the computer that needs to be protected is the same. Therefore, if the hard machine is read on other computers that need to be protected by the non-squatting hard disk drive, the computer identification code of other computers must be with the hard disk. Identification, not the same. Therefore, 'here, check whether the description data 4 has a part that matches the computer identification code set by the computer to decide whether to continue the processing step; (14) Make the disk difficult to divide District 5 has _ cents, and then follow (10) Processing; in the implementation of the financial, please refer to (4) 3, the steps of the disk division of the disk partition is: (140) determine whether the disk partition table 5 in the main boot record is empty If yes, proceed to step (141), otherwise, proceed to step (142); (141) copy the backup disk age storage area 44_with backup disk partition table to the disk partition table area in the master boot record 200825743 5 'Use as a partition table for each disk, that is, end; (142) Each disk partition table exists in the disk partition table area 5 in the master boot record; at this time, the disk is divided into all the disks of the table area 5. The split table is copied to the backup disk partition table storage area 44 to back up the latest financial network _, and the check value is updated to the new value, and the new value is stored in the check code storage area 46, that is, the second brain needs to be reconfirmed. The magnetic 5 in the main boot record is in the empty state, and the disk partition table area 5 originally called the hard disk drive can be read in the cut-off area 5, and the disk partition table can be read in the disk. Therefore, in this + step, you need to confirm the charm to start riding (10) = No for emptying State; 5 ^ (15) Continue the self-test processing, and then finish. (10) Let the disk partition 5 not exist ^Magnetism according to step (11) processing f knife table 're-show, f brain ° ^ _, please Refer to the processing table of Table 4:::: split table area 5 does not exist disk partition (160) to judge the state of the main boot record empty, #=分咖5 is clear step (10)); step (10)), otherwise , (160 copies the main record (4) split table to the backup disk, all the disk tickets of the area 5 is the cut table storage area 44, for -10. 200825743 to use all the disk partition table as a backup disk partition table; (162) The master record (10) is divided into the partition table of the hard disk area 5, that is, the end is completed; the disk (163) main record __distribution area 5 has been cleared, that is, the end. Second sub-power (four) to re-confirm the main boot record disc f cut ^ 5 is expected to be ignorant, the Gu is that the hard disk building may be in W-time reading, is set (four) machine needs to be protected, the electricity "take Therefore, there is already a disk in the _ split table area 5: The cut table 'so' has to determine whether all the disk partition tables are: emptied to prevent the computer from reading the disk partition table. also

And husband j (can know that 'when the hard disk is not in the pure protection, the main boot record 'meaning' that the main boot record does not establish a protection description system Lu Li (four) take the main job record, the ribs complete the start-up operation ', When the hard disk boot protection is activated, the main boot record has been protected «13- 200825743 description data 4, so the protection description data is read through the hard disk drive. 4 The hard disk drive is protected, and the hard disk is judged by the hard disk. Whether it is the same as the other code, so that the computer that reads the hard disk is the computer that sets the hard disk identification code. If it is, it means that the hard disk has not been stolen or read by other computers. The purpose of the data in the hard disk. In this embodiment, the protection description data 4 is stored between the jump area 2 of the main boot record of the main boot area 6 of the hard disk and the disk partition table area 5 In the space (as shown in Figure 7), that is, in the boot code storage area 3 where the boot code is stored, and the computer searches for the unused space between the jump area 2 of the main boot record and the disk split table area 5 Whether there is an identification message to judge the hard disk Whether the machine has a protection description, and the storage capacity of the hard disk identification code storage area 42, the damage disk division table area 44, and the inspection code storage area 46 is a fixed size, so when After the message, it can be calculated from the Lang message. The hard disk identification code storage area 42, the backup disk divided into the county area M and the check code storage area 46 are at the starting address of the main starting magnetic area, so that the computer can be identified by the hard disk. The code storage area 42, the backup disk partition table storage area 44, and the check code storage area 46 read the hard disk identification code, each backup disk partition table, and the check code value at the start address of the main boot magnetic area. Since the boot code storage area 3 of the main boot sector 6 of the disc is not enough to store the material #4, in the other embodiment of the present invention, the computer is in the disc partition table of _. In the area 5, an idle magnetic area 7 writes the protection description data 4' and marks one of the disk divisions of the disk division table area 5 as a special _, and is in the idle (four) disk division-14-200825743 Write the start position of the magnetic area of the space (as shown in the δ diagram), so the computer passes through the fresh face correction 5, B: type _ disk disc, private 谢 谢 ^ ^ disk partition table Side = material 4 at the start position of the _ magnetic area, the identification information can be read ^ another 'since the storage capacity of the hard disk _ replenishment area 42, the backup disk division table area 44 and the check code storage area 46 is fixed The size, therefore, when the computer reads the identification message, it can be calculated by the identification message, the storage area 42, the backup disk partition #] table _ 44 __ storage area 46 in the starting address of the main boot magnetic area, so that The computer can store the Wei 42 according to the hard disk identification code, backup _ minute #_魏 & and check code, 46, in the idle magnetic zone start sister, read the hard disk identification Each backup disk partition table and checksum value. The above description is only a preferred embodiment of the present invention, and the features of the present invention are not limited thereto, and any equivalents that can be easily changed or modified in the field of the invention by those skilled in the art, All of them can be included in the following patent scope of this case.
