Present embodiment provides a kind of method of utilizing basic input/output interface to obtain system mode, first system is connected with second system by basic input/output interface, and basic input/output interfaces such as the serial ports of second system and first system corresponding connection or parallel port are set to control mouthful.First system sends the state that detection information obtains second system via the basic input/output interface of second system to second system, if second system is in state of activation, the basic input/output interface of second system is to first system's return information, first system can control operation such as switch to second system, otherwise first system prompt, the second system exception state information, avoid second system is carried out misoperation, keep controlled, friendly operation interface.Utilize agreement between plate to obtain the state of interconnective subordinate system in the existing multicomputer system, need wait until the state that just can know the subordinate system after subordinate's system initialization, and the basic input/output interface of present embodiment utilization obtains the mode of system mode, can be in the BIOS initial phase in the subordinate system, can know that system is in starting state, not the phenomenon of existence response lag; And need certain application of system mode that information is provided for follow-up, be convenient to subsequent operation.
Method embodiment two flow charts that Fig. 3 obtains for system mode of the present invention.Before step 1 shown in Figure 2, also comprise in the present embodiment:
Obtain the call number of the input/output interface of second system's correspondence;
Judging whether basic input/output interface is number corresponding with described call number, is then to send detection information to second system; Otherwise carry out respective handling.
Illustrate: each respectively corresponding one second system of string slogan of first system, different string slogans is corresponding with the second different systems, when first system need obtain the state information of certain second system, obtain the serial ports call number of this second system correspondence, thereby send detection information to second system that correspondence string slogan connects.As: first system is connected with four second systems 2,1,3,4 respectively by serial ports 1, serial ports 2, serial ports 3, serial ports 4, and promptly the serial ports 1 of first system connects second system 2, and serial ports 2 connects second 1... of system.To obtain the state of second system 1 as first system, retrieve corresponding call number serial ports 2, thereby only send detection information to second system that serial ports 2 connects.If basic input/output interface is number corresponding with described call number, then export information.
In like manner, if first system will use the parallel port to survey the state of second system, second system at first must use the parallel port as basic input/output port so, secondly, the interface that is connected back-to-back with second system in first system, also must a parallel port on the physical attribute, first system is connected with second system when obtaining second system mode by the parallel port, need to detect also whether slogan is corresponding with the call number of second system, thereby the parallel port to correspondence sends detection information, the detailed process and the serial ports course of work are similar, are not described in detail in this.
Method embodiment three flow charts that Fig. 4 obtains for system mode of the present invention.As shown in Figure 4, present embodiment is compared with Fig. 3 embodiment, also comprises:
Obtain the type of the system that links to each other with first system; Judging whether this system satisfies the second system type feature, is then to send detection information to this system; Otherwise do not send detection information or information.
Present embodiment further detects the category feature that whether satisfies second system with interconnective system of first system, and when not satisfying the second system type feature, first system is information directly, has saved subsequent step.
Below present embodiment being applied to multicomputer system is illustrated: main system is by being provided with hardware ID sign main system type, and the subordinate system is provided with another hardware ID sign subordinate system type, and identical system type is provided with same hardware ID.When main system need switch to certain subordinate system, when surveying this system and whether being in state of activation, whether satisfy the type feature of subordinate system by judging this system, thereby send detection information to the system that satisfies subordinate's system type feature.
In the multicomputer system, can insert a plurality of plug-in cards on the PCI slot of main system, comprise interfaces such as 2 cover Ethernet interfaces, serial ports, parallel port in each plug-in card, this 2 socket connects back-to-back.One socket is connected with main system, another set ofly then is connected with the subordinate system.Be provided with the hardware ID value in each plug-in card, main system is by detecting this ID value, and whether what judge this plug-in card opposite side connection is the subordinate system of main system, if then send order or detection information to this subordinate system.If do not connect plug-in card on the slot, perhaps the discontented foot of the plug-in card that connects on the slot belongs to the type feature of system, then skips subsequent step, can directly point out information such as handoff failure, has saved follow-up time.
The method that Fig. 5 obtains for system mode of the present invention is applied to serial ports embodiment flow chart.As controlling the characteristic that mouth carries out the order line echo, subtend second system sends detection information and receives the further refinement of process of return information present embodiment at serial ports.As shown in Figure 5, present embodiment specifically comprises:
Step 10: the capable information of first system's input command, need obtain a certain second system mode or a certain second system is carried out operations such as switching controls;
Step 11: first system judges that whether the system that is connected with serial ports satisfies the type feature of second system, as satisfy execution in step 12, otherwise execution in step 15;
Step 12: first system obtains the serial ports call number corresponding with this second system;
Step 13: first system judges whether the string slogan is corresponding with described call number, is execution in step 14 then, otherwise execution in step 15;
Step 14: first system enables this serial ports transmitting-receiving, sends carriage return character, execution in step 20 by this serial ports to second system of correspondence;
Step 15: point out the second system exception state information, for example: switch to second thrashing, second system and be in and crash or state information such as shutdown;
Step 20: the first in first out (First in first out is called for short FIFO) that this serial ports is read in the repeating query of first system receives buffering area;
Step 21: judging whether to receive return character, is execution in step 23 then; Otherwise execution in step 22;
Step 22: delaying time judges whether to surpass the time of setting after 1 millisecond, as: 1 second, do not receive any response character yet if surpass 1 second, then close this serial ports transmitting-receiving, execution in step 15; Otherwise execution in step 20 continues to read this serial ports receives fifo buffer;
The response character of second system can not return sometimes immediately, receives fifo buffer so read once this serial ports every 1 millisecond, if do not receive any character yet after having arrived 1 second, then judges second system exception;
Step 23: prompting handover success information, represent that second system is in state of activation, can control second system.
When second system is in state of activation, its control mouth (present embodiment with the serial ports of second system as control mouthful) is in case received any one character, just can beaming back with this character former state, turn back to the serial ports that is connected with first system, this character just can be received by this serial ports by first system.If the serial port drive program of first system has been received any character within 1 second, judge that second system is in state of activation, can report to enable successfully, switch to the operation of second system, prompting user handover success.Otherwise, judge second system exception, information such as the prompting handoff failure or second system exception.Certainly, first system can also be by serial ports other characters beyond second system control mouthful transmission carriage return character, for example: " t ", when activating, second system can return identical character to first system equally, promptly can reach and judge whether second system is in the purpose of state of activation, so but this kind situation is owing to will return not too close friend of concrete character interface, and it is minimum to user's influence to send carriage return character, so common first system sends carriage return character by serial ports to second system.
