Abstract
The invention discloses a kind of method of upgrading blade motherboard configuration information in system starting process, belong to a kind of method of upgrading blade motherboard configuration information, the configuration information of blade mainboard is kept in the EEPROM; Administrative unit stops to visit blade SMBUS equipment after the I/O mouth of IIC/SMBUS IO chip becomes high level; The configuration information of BIOS blade carries out self check, and north bridge chips reads the interior information of EEPROM on the external bus after finishing, and compares with detected information, the identical EEPROM, the EEPROM that then covers inequality of just not changing; North bridge chips read and write back Super IO chip with that put the I/O of high level salty newly be set to low; Administrative unit continues blade SMBUS equipment and conducts interviews.The present invention upgrades blade mainboard basic hardware configuration information by the SMBUS bus in the blade start-up course, simplified program, has increased the stability of system.
Description
Technical field
The present invention relates to a kind of method of upgrading blade motherboard configuration information, specifically a kind of method of in system starting process, upgrading blade motherboard configuration information.
Background technology
So-called blade server (says accurately and should be called blade server) but be meant the server unit of a plurality of cassettes of plug-in mounting in the rack cabinet of calibrated altitude, realize the available and high density of height.Be the high available highdensity low-cost server platform of a kind of realization, be special applications industry and high density computing environment specialized designs.Each piece " blade " in fact is exactly a block system mainboard.They can as Windows NT/2000, Linux etc., be similar to one by one independently server by the operating system of " plate carries " hard disk startup oneself, under this pattern, the system of each piece " blade " operation oneself serves the different user group of appointment, does not have association each other.
SMBUS is the abbreviation of System Management Bus, and it mainly is by a cheapness and powerful bus (being made up of two lines), comes the equipment on the control main board and collects corresponding information.SMBUS provides a control bus for system and the such task of power management, uses the system of SMBUS, and sending and receive message between the equipment all is by SMBUS, rather than uses independent control line, can save the number of pins of equipment like this.Use SMBUS, equipment can also provide its production information, tells system its model, and part number etc. at its state of preservation of some incidents, reports different classes of mistake, the reception controlled variable, and return its state etc.
Summary of the invention
Technical assignment of the present invention provides a kind of a kind of method of upgrading blade motherboard configuration information in system starting process of upgrading blade mainboard basic hardware configuration information by the SMBUS bus in the blade start-up course.
A kind of method of in system starting process, upgrading blade motherboard configuration information of the present invention, technical scheme is: the basic hardware configuration information of blade mainboard is kept in the EEPROM; Administrative unit is by reading the I/O mouth state of IIC/SMBUSIO chip, the SMBUS bus apparatus that judges whether to visit blade inside; Administrative unit stops to visit the SMBUS bus apparatus of blade inside after the I/O of IIC/SMBUS IO chip becomes high level; The basic hardware configuration information of BIOS blade mainboard carries out self check, north bridge chips reads the interior information of preserving of EEPROM on the external bus after finishing, and and the basic hardware configuration information of detected blade mainboard is compared, the identical information of preserving in the EEPROM that just do not change, the information of preserving in the EEPROM that then covers inequality; North bridge chips read and write back Super IO chip with that of IIC/SMBUS IO chip put the I/O of high level salty newly be set to low; The SMBUS bus apparatus that administrative unit continues blade inside conducts interviews.
Concrete steps are:
(1), the basic hardware configuration information of blade mainboard is saved in the EEPROM;
(2), after blade powers on, blade is in system starting process, BIOS control Super IO chip is opened bus switch 2 and bus switch 3, and bus switch 1 and bus switch 4 are closed, and this moment, BIOS carried out self check by the basic hardware configuration information of Super IO chip by bus switch 2 and 3 pairs of South Bridge chips of bus switch and north bridge chips inner blade mainboard;
(3) and BIOS control Super IO chip produce the I/O mouth that a high level state is given IIC/SMBUS IO chip; When the administrative unit of blade server reads the IIC/SMBUS status register, the high level state of an I/O mouth by IIC/SMBUS IO chip learns that this moment, blade was in the system starting process, and administrative unit just stops the visit to the SMBUS bus apparatus of this blade inside;
(4), finish the self check of basic hardware configuration information of blade mainboard as BIOS after, can control Super IO chip bus switch 1 and bus switch 4 are opened, at this moment South Bridge chip and north bridge chips just can be visited the EEPROM on the external bus;
(5), north bridge chips read the information of preserving in the EEPROM and and the basic hardware configuration information of detected blade mainboard compare, if coming to the same thing relatively, illustrate and do not change hardware configuration on the blade, then do not write EEPROM again, if result relatively is inequality, illustrate that the hardware configuration on the blade has had variation, at this moment just the basic hardware configuration information of new detected mainboard is write in the EEPROM, override original old information;
(6), after having write EEPROM, Super IO chip is closed bus switch 1 and bus switch 4, and with that of IIC/SMBUS IO chip put the I/O of high level salty newly be set to low, South Bridge chip and north bridge chips and external bus have disconnected again like this, and administrative unit is learnt and can be continued to have visited the SMBUS bus apparatus of this blade by reading the IIC/SMBUS status register contents.
A kind of method of upgrading blade motherboard configuration information in system starting process of the present invention is compared with prior art, realized in the blade start-up course, reading and upgrading the basic hardware configuration information of blade mainboard by the SMBUS bus, simplified program, increased the stability of system, thereby, have good value for applications.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Accompanying drawing 1 is a kind of process flow diagram that upgrades the method for blade motherboard configuration information in system starting process;
Accompanying drawing 2 is a kind of sequential synoptic diagram that upgrades the method for blade motherboard configuration information in system starting process.
