Description
The present invention relates to a kind of starting-up method of computer system, wreck, also can finish the computer system starting method of start-up routine even relate in particular to a kind of system basic input/output (BIOS) sign indicating number.
Present personal computer system no matter be that the progress on processing speed or the usefulness is all quite fast, and the cycle of central processing unit (CPU) product also obviously shortens significantly.CPU manufacturer takes to develop earlier the CPU product to strive for the timeliness business opportunity in order to adapt to the of short duration research and development time more; Hou, system's microcode (micro code) is upgraded the mode of (update), microcode is delivered to system manufacturer again, when being written into (post), microcode is changed, to guarantee the correctness of CPU product at system bios.Except that this, CPU manufacturer requires system manufacturer to be mated more, interface (interface) must be provided in system bios, allow user (end users) buy back product Hou, can need to be provided by CPU manufacturer the microcode of (regularly or at any time upgrading) to be burned onto among the BIOS according to it: therefore, when the user is with booting computer at every turn, BIOS promptly can carry out more new element of microcode earlier, carry out the BIOS start-up routine of general computer system again, allow the user can enjoy up-to-date version.
Yet this method is to have opened a back door of destroying system in computer system for hacker or other persons who is ambitious or tenacious of purpose far and away.Though CPU manufacturer uses the mode of checking with (checksum) to confirm whether the microcode among the burned BIOS is correct; But for the people who makes trouble on purpose, but, allow computer system after being written into wrong microcode, CPU is crashed and can't move as long as check and (checksum) correct microcode or the mode of Virus to forge.
In order to address this problem, the present invention proposes a kind of computer system starting method of novelty, even BIOS sign indicating number (that is the microcode that will upgrade) also can be finished the BIOS start-up routine of general computer system, and allow computer system can continue to operate starting-up method when wrecking.
The present invention mainly is the keyboard BIOS (keyboard BIOS) that fully uses computer system, if the deadlock phenomenon takes place in the process that microcode is upgraded CPU, then system will stay necessary record (setting some signs), and starts shooting again.Again Kai Ji computer system will can not carried out the renewal of microcode again, and directly finish the BIOS start-up routine of general computer system, therefore can keep away the problem that CPU crashes.For the what user, can obtain correct microcode again, to repair the mistake among the BIOS again by CPU manufacturer place.
In order to achieve the above object, the computer system starting method that the present invention proposes comprises the following steps:
Computer system boot-strap Hou, as carrying out the renewal of system's microcode, then notify keyboard BIOS (keyboard BIOS) will carry out the renewal of system's microcode on inspection; And, carrying out more new element Hou of system's microcode, above-mentioned keyboard BIOS is through one first special time, if do not receive that one is updated to function signal, then set a failure flags, and impel above-mentioned computer system shutdown earlier, just make above-mentioned computer system start shooting again through one second special time Hou again.
Wherein, if above-mentioned failure flags what last time was set during computer system boot-strap, above-mentioned computer system then start Hou, need not to carry out the renewal of system's microcode, above-mentioned computer system is also being set a Hou of upgrading prohibitory sign, proceeds the BIOS start-up routine of general computer system.
In addition, if above-mentioned renewal prohibitory sign what last time was set during computer system boot-strap, above-mentioned computer system is then start Hou, directly carry out the BIOS start-up routine of general computer system: otherwise, whether be set according to above-mentioned failure flags again, and whether decision carries out the more new element of system's microcode.
For above-mentioned purpose of the present invention, characteristic can be become apparent, especially exemplified by preferred embodiment, and conjunction with figs., be described below in detail:
Fig. 1 is the main action flow chart of the embodiment of the invention;
Fig. 2 is the action flow chart of embodiment of the invention mid-game key BIOS.
Fig. 1 is for showing the main action flow chart of the embodiment of the invention, in Fig. 1 embodiment, mainly be that sign (failure flags, upgrade prohibitory sign) respectively is set on the keyboard BIOS of computer system and CMOS, whether be set according to above-mentioned sign, determine whether needing to upgrade system's microcode of computer system CPU.
With reference to Fig. 1, with computer system boot-strap Hou, at first, read the renewal prohibitory sign by CMOS, judge whether it is set (step S1), in this embodiment, for example: judge whether its value is set to " 1 ".If CMOS confirm to upgrade prohibitory sign and is set to " 1 ", then system bios can not carried out the action that the cpu system microcode is upgraded, and promptly proceeds the start-up routine (step S6) of General System BIOS, the Hou civilian dress go into operating system OS.
If CMOS confirm to upgrade prohibitory sign and is not set to " 1 ", then reads failure flags by keyboard BIOS, the microcode when confirming last time to start shooting is upgraded whether success (step S2).In this embodiment, if the microcode last time when starting shooting is upgraded failure, then the value of above-mentioned failure flags system is set to " 1 "; Otherwise, if the successful then value of above-mentioned failure flags of renewal last time is not set to " 1 ".
If keyboard BIOS confirms that last time microcode was upgraded failure (value that is failure flags is set to " 1 " already), then system bios will can not carry out the renewal of system's microcode, and the value of above-mentioned renewal prohibitory sign is set at " 1 " (step S7); Hou, system bios is promptly proceeded the start-up routine (step S6) of General System BIOS, the Hou civilian dress go into operating system OS.
If keyboard BIOS confirms that last time microcode was upgraded successfully (value that is failure flags is not set to " 1 "), system bios is notify keyboard BIOS, prepared to carry out the renewal (step S3) of system's microcode, Hou promptly carry out the renewal (step S4) of system's microcode.If the correct no abnormal state of the renewal of system's microcode produces, then make system bios inform keyboard BIOS, the microcode of being carried out is new element successfully (step S5) more; Hou, system bios is promptly proceeded the start-up routine (step S6) of General System BIOS, so that loading of operating system OS.
Be noted that: whether when keyboard BIOS learnt that system bios has prepared to carry out system's microcode renewal, keyboard BIOS also can cooperate the monitoring of carrying out system's microcode renewal situation, successful with the renewal of learning system's microcode; Wherein, the action of keyboard BIOS steps flow chart as shown in Figure 2.
Whether with reference to Fig. 2, keyboard BIOS learns that system bios prepares to carry out microcode and upgrade (step T1) Hou, promptly monitor in what one first special time, receives that system bios notice microcode upgrades successful signal (step T2).
If, determining to receive the successful signal of above-mentioned microcode renewal in the above-mentioned very first time of keyboard BIOS what, keyboard BIOS promptly removes the action (step T3) of failure flags, makes the value of failure flags not be " 1 "; Hou, keyboard BIOS gets back to the state (T6) of waiting for other orders again.
Again if, if, fail to receive the successful signal of above-mentioned microcode renewal in the above-mentioned very first time of keyboard BIOS what, the expression microcode is upgraded baulk, so keyboard BIOS promptly will carry out the setting (step T4) of failure flags, the value that also is about to failure flags is set at " 1 ".Hou, the Hou boot action again (step T5) again that keyboard BIOS can impel computer system to shut down, also be powered-down Hou wait for one second special time (for example 1 second) more again the start.Again the Hou of starting shooting is promptly repeated process step shown in Figure 1 again.
From the above, the present invention fully uses the keyboard BIOS of computer system (keyboardBIOS), if the deadlock phenomenon takes place in the process that microcode is upgraded CPU, then system will stay necessary record (set failure flags, upgrade prohibitory sign), and starts shooting again.Again Kai Ji computer system, its system bios will can not carry out the renewal of microcode again, and directly finish the BIOS start-up routine of general computer system, the problem that can avoid CPU to crash thus.For the what user, can not upgrade mistake, and cause computer system to crash and paralysis because of microcode once, and system's microcode execution work that still can be original; The user only needs to obtain correct microcode again from CPU manufacturer, and the mistake of repairing among the BIOS gets final product.
When the user is burned onto in the system bios again with correct microcode, and the Hou of having repaired the system bios sign indicating number that wrecks, above-mentioned computer system then can be removed above-mentioned renewal prohibitory sign.
Though the present invention discloses as above with preferred embodiment; but be not in order to limiting the present invention, anyly be familiar with this skill person, without departing from the spirit and scope of the present invention; might do a little changes and retouching, so protection scope of the present invention should be as the criterion with the scope that claim was defined.
