S212, CPU21 accesses bus 251 by storage chip and loads BIOS220 from storage chip 22, to initialize;
S213, after BIOS loads successfully, CPU21 accesses bus 252 from firmly by hard disk under the guiding of BIOS220The MBS of dish 23 loads MBR231; If BIOS loads unsuccessfully, follow-up flow process cannot continue to carry out, electronic equipment20 cannot normally start;
S214, CPU21 accesses bus 252 by hard disk and scans in the MBS of hard disk 23 under the guiding of MBR231DPT232, hard to determine a Boot software 233a and the 2nd Boot software 233b and the each leisure of operating system 234Residing corresponding subregion in dish 23;
S215, CPU21 obtains Boot to be loaded under the guiding of MBR231 from logic device 24 by logic bus 253The mark 240a of software, to determine that current selection loads a Boot software 233a;
S216, CPU21 accesses bus 252 by hard disk and loads the from the corresponding sector of hard disk 23 under the guiding of MBR231One Boot software 233a;
If a Boot software 233a loads successfully,, as shown in the S217 in Fig. 3 a, CPU21 is at a Boot softwareUnder the guiding of 233a, access the corresponding sector load operation system 234 of bus 252 from hard disk 23 by hard disk.
If a Boot software 233a loads unsuccessfully, referring to Fig. 3 b:
S221, logic device 24 is set to reset mode by the reseting pin Rst that controls CPU21 by CPU21, and will treatThe mark 240 that loads Boot software changes to and represents the 2nd Boot software 233b, then by controlling the reset transistor of CPU21Pin Rst removes the reset to CPU21, in Fig. 3 b, will represent that this mark 240 when the 2nd Boot software 233b is designated 240b;
S222, CPU21 accesses bus 251 by storage chip and again loads BIOS220 from storage chip 22, at the beginning of carrying outBeginningization;
S223, after BIOS loads successfully, CPU21 accesses bus 252 from firmly by hard disk under the guiding of BIOS220The MBS of dish 23 loads MBR231; If BIOS loads unsuccessfully, follow-up flow process cannot continue to carry out, electronic equipment20 cannot normally start;
S224, CPU21 accesses bus 252 by hard disk and scans in the MBS of hard disk 23 under the guiding of MBR231DPT232, hard to determine a Boot software 233a and the 2nd Boot software 233b and the each leisure of operating system 234Residing corresponding subregion in dish 23;
S225, CPU21 obtains Boot to be loaded under the guiding of MBR231 from logic device 24 by logic bus 253The mark 240b of software, to determine that current selection loads the 2nd Boot software 233b;
S226, CPU21 accesses bus 252 by hard disk and loads the from the corresponding sector of hard disk 23 under the guiding of MBR231Two Boot software 233b;
If the 2nd Boot software 233b loads successfully,, as shown in the S227 in Fig. 3 b, CPU21 is at the 2nd Boot softwareUnder the guiding of 233b, access the corresponding sector load operation system 234 of bus 252 from hard disk 23 by hard disk.
If the 2nd Boot software 233b loads unsuccessfully, a Boot software 233a and the 2nd Boot software 233b all damage,May cause electronic equipment 20 normally to start.
The one Boot software 233a and the 2nd Boot software 233b all damage may be because: the one Boot software 233a damageAfter not in time repair, after this, the 2nd Boot software 233b due to same damage of the similar reason of a Boot software 233bBad.
For this reason, this embodiment can be identical or an essentially identical Boot software 233a and the 2nd Boot software of software content233b gives respectively primary and backup identity, and, the mark 240 of Boot software to be loaded can be further by its expressionThat the one Boot software 233a is designated is primary, the 2nd Boot software 233b of its expression is designated for subsequent use.
Correspondingly, a Boot software 233a and the 2nd Boot software 233b can be further used for guiding CPU21 to pass through to knowThis mark 240 that other logic device 24 is safeguarded is determined the activestandby state of the Boot software of current loading, that is, mark 240 not onlyBe used for distinguishing a Boot software 233a and the 2nd Boot software 233b, also further there is the physical meaning that represents active and standby identity,For example, the active and standby identity that the corresponding Boot software 233a of mark 240a and mark 240a represent is primary, mark 240bThe active and standby identity that corresponding the 2nd Boot software 233b and mark 240b represent is for subsequent use. Thereby:
Refer to the S230 of Fig. 3 c, CPU21 (can be identical or large with the S216 in Fig. 3 a by the S216 shown in Fig. 3 cCause identical) successfully loaded a Boot software 233a after, under the guiding of a Boot software 233a by logic totalThe mark 240a that line 253 is identified Boot software to be loaded from logic device 24 represents primary, and therefore CPU21 can pass throughS217 load operation system 234 shown in Fig. 3 a.
Refer to the S240 of Fig. 3 d, CPU21 (can be identical or large with the S226 in Fig. 3 b by the S226 shown in Fig. 3 dCause identical) successfully loaded the 2nd Boot software 233b after, under the guiding of the 2nd Boot software 233b by logic totalThe mark 240b that line 253 is identified Boot software to be loaded from logic device 24 represents for subsequent use, and therefore, CPU21 is secondUnder the guiding of Boot software 233b, utilize the 2nd Boot software 233b to repair a Boot software 233a, as the S241 in Fig. 3 dShown in; And after utilizing the 2nd Boot software 233b reparation the one Boot software 233a, CPU21 can be as Fig. 3 dIn S242a shown in like that under the guiding of the 2nd Boot software 233b load operation system 234 (with the S227 in Fig. 3 bIdentical or close), primary Boot software and Boot software for subsequent use are used to guide the loading of operating system 234 coequally.
