System, the device and method of remotely located CMOS parameters【Technical field】
The present invention relates to field of computer technology, more particularly to a kind of system of remotely located CMOS parameters, device and sideMethod.
【Background technology】
CMOS (Complementary Metal Oxide Semiconductor, complementary metal oxide semiconductors (CMOS)) isThe semi-conducting material that a kind of large-scale application is manufactured in IC chip.In computer and the communications field, generally by CMOSRAM (complementary metal oxide semiconductors (CMOS) random access memory) is referred to as CMOS.That is CMOS is often referred to readable writeable random storageChip, for preserving important hardware configuration information and User Defined parameter in computer system, such as CPU (CentralProcessor Unit, central processor unit) frequency, the sequential of internal memory, the date of system, the state of hard disk, floppy driveSpecification, boot sequence of bootable equipment of user's setting etc..
System can read the hardware configuration information in CMOS to initialize system itself during due to start, read userCustomized parameter realizes some special functions.The parameter for thus being preserved in CMOS is critically important, it is impossible to lose easily.GenerallyBy being that the backup battery of uniform block independence is powered, so either normal shutdown or system accident power down is preserved CMOS in CMOSHardware information and User Defined parameter all without loss.
BIOS (Basic Input Output System, basic input output system) is typically to be stored in read-only ROMExecutable binary code in (Read Only Memory, read-only storage) chip.These executable binary system generationsCode include the most important basic input/output routine of system, system configuration information, startup power on self detection and initialization program andInterruption service that operating system and application program during for operation are provided etc..After system boot can by the hardware configuration in BIOS,System default parameter and User Defined parameter are loaded into CMOS, are set for user and changed.When starting shooting again below, someImportant parameter system directly can read from CMOS, so as to accelerate starting up speed.
Due to the CMOS chip for just having dispatched from the factory, its content is a group invalid " FF " or " 00 " write by chip producer,This is to system without any practical significance.Thus, in first time start operation bios program, BIOS can report that cmos data goes outMistake, points out user to load one group of default value from BIOS by corresponding hot key, and the default value is that one group of acquiescence for system hardware is joinedThis group of default parameters, is write CMOS chip, so as to complete the initialization to CMOS by number.These default parameters can ensure systemNormal hardware initialization is carried out, starting device is selected according to the boot sequence of acquiescence, control is submitted in starting deviceOperating system, and the interrupt service routine of bottom is provided for operating system and operation application program in an operating system.That is, BIOS can provide effective initialization acquiescence Value Data for CMOS, and the data can guarantee that system is normally run and worked.
Additionally, BIOS provides the operation interface of personal-machine interaction, CMOS parameters are set according to the actual requirements for user,Generally after start when bios program is run, can point out user by hot key " DEL " or " F2 " (different BIOS producers, settingHot key may be different, and corresponding hot key is pressed in the prompting according to BIOS) enter the human-computer interaction interface of BIOS offers so as to rightCMOS parameters are configured.After being provided with, preservation backed off after random is carried out by corresponding hot key, now, user provide in BIOS thisThe parameter set in one human-computer interaction interface has been written in CMOS chip, and previous BIOS writes the respective default of CMOS chipParameter has been capped.That is, the human-computer interaction interface that user can provide in BIOS is configured to CMOS parameters.
When the CMOS parameters that user sets mistake cause system to be unable to normal boot-strap, user can be by first disconnecting systemAlternating current, then pulls out the battery powered for CMOS or the jumper switch being integrated in by short circuit on mainboard, realizes removing CMOSThe operation of parameter.Content so in CMOS chip reverts to default value " FF " or " 00 " when chip dispatches from the factory again.Work as during startAfter BIOS detects this situation, can report that user's cmos data malfunctions, point out user to be loaded from BIOS by corresponding hot keyDefault value, or system loads default value from BIOS automatically, is once initialized so as to be done again to CMOS.
The method of traditional this set CMOS parameters, due to needing user to enter into BIOS offers by corresponding hot keyHuman-computer interaction interface could be realized setting to CMOS parameters, therefore user must arrive the working site of target machine to be placed, such asFruit is the machine of batch, and is dispersed in apart from far different multiple place, then more inconvenient, while also improving intoThis.And the method for traditional this set CMOS parameters is, it is necessary to hardware input-output equipment (such as key for placing one's entire reliance upon externalDisk, display etc.), if without external hardware input-output equipment, user cannot complete CMOS parameters by the demand of oneselfSetting.
For these defects, the method for traditional setting CMOS parameters also has using BMC (Baseboard ManagementController, baseboard management controller) realize the setting of CMOS parameters.Functionally, similar to CPU, it has certainly BMCOneself internal memory and BIOS (commonly referred to BMC Firmware, substrate management controller firmware), by BMC and belongs in BMCDeposit and BIOS, a BMC system can be constituted.The method will use the multiple computers of BMC chip, mutual by network or serial portsEven, then said the word come the BMC to other computers as console using wherein one computer.This mode is extra hard by buildingEven if the target machine that part logic realizes CMOS to be modified does not have external hardware input-output equipment, it is also possible to byIts BMC says the word to realize the setting to CMOS parameters.
However, the method that this use BMC realizes CMOS parameter settings, because BMC is one piece of very expensive chip, itThe price of itself is generally more taller than general CPU prices, is generally used for middle-and high-end server, therefore cost is very high, generalAll without band BMC chip, without BMC chip, the above method cannot then be realized computer.Additionally, the method is built due to needingExtra hardware logic circuit, implements complexity, and also improve cost.
