It implements BIOS safety protection; provides more reliable BIOS upgrading means; the BIOS data is stored in the HPA, uneasy to be destroyed; because it only needs the harddisc, it can in time and reliably recover the BIOS; it need not display in the automatic repairing course, needs no input device and also reduce the trouble in user interference and operation.
Description
Technical field
The present invention relates to a kind of automatic recovery basic input output system of computer (BasicInput/Output System; abbreviation BIOS) method; be meant a kind of especially based on hard disk protection space (Host Protected Area; be called for short HPA) the interior BIOS file that backs up; when starting computing machine to the detection of BIOS; automatically the method for reparation or upgrading BIOS belongs to the computer security technique field.
Background technology
Along with popularizing of computing machine, the competition of computer circle is growing more intense.Computer hardware is constantly upgraded, and supporting thereupon software module also will be upgraded.With computer motherboard, the kernel software module that its BIOS module is control main board work, but because the update of mainboard is increased, and the development﹠ testing cycle of mainboard BIOS shortens, the situation of the latent defect of BIOS module also day by day increases.In order to support new hardware better, for example (ATA is a kind of interface specification of hard disk to the S-ATA hard disk, is mainboard and hard-disk interface commonly used in the present PC in addition; S-ATA: serial ATA, a kind of interface specification of new hard disk), provide BIOS upgrade function in a lot of mainboard producers, the user can oneself utilize producer that BIOS is provided upgrading tool, BIOS on the mainboard is upgraded, replace original BIOS module of mainboard, the defective that exists in the BIOS module before can solving on the one hand can be supported new hardware device on the other hand better.
At present BIOS upgrading mode is fairly simple, and the user obtains (as downloading from mainboard producer website) behind the new BIOS file, operation ROMPaq, user and ROMPaq carry out necessary mutual after, just use new BIOS module and replace the original BIOS module of mainboard.
Because the manufacturer of mainboard is a lot, the mainboard kind of same producer is also many, and the user might be with the upgrade BIOS module of own computer motherboard of the BIOS file that does not match.And in BIOS module upgrade process, because technical reason, whether ROMPaq can not mate by new BIOS file and the mainboard of self-verifying; Therefore, if the user selects wrong BIOS file, just probably cause mainboard not work.In addition, outage, program exception situation such as withdraw from and also all can cause BIOS upgrading failure in the upgrading BIOS process, make the mainboard cisco unity malfunction.When the problems referred to above occurring, the user can't oneself solve, and mainboard need be delivered to special maintenance department and keep in repair, and is very inconvenient.
At present, provide a kind of when BIOS is destroyed among the BIOS of part mainboard, under specific situation, repair the method for BIOS: at first, even being provided with in the BIOS module when BIOS upgrades also is the program module (BootBlock) that remains unchanged, when this module also is the computer starting guiding, the inlet of BIOS module.Therefore, during computer starting, at first can move the BootBlock program, if BIOS goes wrong, and, the floppy drive, industrial standard architectures (the Industry StandardArchitecture that have disposed on the computing machine, be called for short ISA) display card and keyboard, then the BootBlock program just can be from shirtsleeve operation system of floppy disk guiding, and then, the user recovers the BIOS module of mainboard with the BIOS file of backup on floppy disk.This method can solve some problems that may occur in the process of upgrading BIOS module in some cases.
But present floppy drive is not the PC standard configuration gradually yet; If the user does not shift to an earlier date the back-up BIOS file, or the floppy disk of back-up BIOS file goes wrong; Or the user does not have ISA display card (present display card mainly is AGP, and seldom some is PCI, the display card of ISA interface seldom on the market, even some mainboards do not have the ISA interface yet at present, can't support the ISA display card) just can not recover BIOS.
In addition, during routine work, the BIOS module also might be because a variety of causes be destroyed.In the case, user's BIOS module does not back up often.Therefore, how to improve the stability of BIOS module, when guaranteeing that the BIOS module is destroyed, how making things convenient for timely reparation BIOS module is exactly an important problem.
HPA is a specific character of the hard disk stipulated in ATA and the S-ATA standard.Support the hard disk of this characteristic, can guard space be arranged in the final stage space of hard disk by some instructions, the data that the back guard space is set can not be accessed.Visit guard space if desired, need same with ATA instruction unpack hard disk protection space.Therefore can utilize this specific character of hard disk to guarantee the BIOS safety of data that is used for recovering automatically the BIOS module of preserving.Because BIOS at most need be with several megabyte (1 megabyte=1,000,000 byte); And present general tens G bytes of hard disk (1G byte=1,000,000,000 byte), so HPA can be arranged to enough greatly, is used to provide enough spaces to preserve a plurality of BIOS and backs up.
