Power-on self-test.
It should be understood that the memory on board of the embodiment of the present invention is the internal memory being integrated on mainboard, such as can be generally in pen
Remember the internal memory used in this computer and all-in-one.Initial mainboard identification number for example can be the GPIO (General from CPU
Purpose Input Output) value that reads at pin, usual GPIO number of pins is limited, for example, two.Internal memory
Information is, for example, memory SPD information, and memory information is, for example, multiple memory informations, and each memory information has the identification number of itself,
Corresponding with mainboard identification number, correspondence here can be identical or corresponding.The memory information of the present invention is stored in BIOS chips,
For example, in ROM (read-only storage) parts or CMOS parts.
It should also be understood that flag value can be arbitrary, either 1 or 0, the scheme of the embodiment of the present invention is suitable for,
One specific embodiment, can be first for no matter whether the identification number of memory information is more than the number of initial mainboard identification number
FLAG values are set in advance as 0, certain not limited to this of the embodiment of the present invention, such as in the case where changing BIOS chips sometimes,
Current FLAG values are 1, can be changed into 0 after restarting, thus using the embodiment of the present invention scheme realize it is automatically true
Determine mainboard identification number, and then configure memory information, without being set in advance to FLAG values.
The beneficial effect of the embodiment of the present invention is：The scheme of the embodiment of the present invention can be due to configuring memory on board not
During success, change in EC and flag value is set, re-start calculating to be configured, therefore the number of mainboard identification number can be increased
Mesh, and performed using EC and restart and change flag value, so as to realize increase mainboard identification number using simple configuration.Change sentence
Talk about, for example, if two GPIO pins, then can set four initial mainboard identification numbers, can using the solution of the present invention
With 8 mainboard identification numbers of mark, so as to more one times of memory information, without increasing the number of GPIO pin, or change
Wiring.
According to Fig. 1 method, if the identification number of memory information is not more than reserved mainboard identification number quantity, initial mainboard

Value and initial mainboard identification number determine mainboard identification number, including：When current flag value is 0, using initial mainboard identification number as master
Panel sign number, when current flag value is 1, current flag value is placed in initial mainboard identification number highest order and obtains mainboard identification number.
According to Fig. 1 method, change current flag value when current power-on self-test is failed, including：When above electric from currently
When self-test has started unfinished after the scheduled time, change current flag value, the scheduled time is more than the conventionally electric of computer
The self-test time.
According to Fig. 1 method, EC calculates the scheduled time using its watchdog circuit, and the scheduled time is to watchdog circuit
(WATCHDOG) stand-by period of setting.
It should be understood that watchdog circuit can be a module in EC, or single circuit, be controlled by EC
System, this is not limited by the present invention.
According to Fig. 1 method 100, when configuring memory on board completion, BIOS chips are sent to EC terminates watchdog circuit
Enable signal is gone in operation.
Fig. 2 is the schematic block diagram of control device according to another embodiment of the present invention.Fig. 2 control device 200 with

Scale value, BIOS chips 210 are stored with memory information table, and memory information table includes the memory information with different identification number；Read
Initial mainboard identification number, initial mainboard identification number be the memory information based on the configurations match with memory on board identification number and
What reserved mainboard identification number quantity determined, initial mainboard identification number is less than reserved mainboard identification number quantity；According to current flag value
Mainboard identification number is determined with initial mainboard identification number；Search to have in internal memory information table according to mainboard identification number and identified with mainboard
The memory information of identification number corresponding to number configures memory on board,
EC 220 is configured as：Change current flag value when current power-on self-test is failed and send instruction of restarting to enter
Enter power-on self-test next time.
The beneficial effect of the embodiment of the present invention is：The scheme of the embodiment of the present invention can be due to configuring memory on board not
During success, change in EC and flag value is set, re-start calculating to be configured, therefore the number of mainboard identification number can be increased
Mesh, and performed using EC and restart and change flag value, realize increase mainboard identification number using simple configuration.
According to Fig. 2 control device 200, if the identification number of memory information is not more than reserved mainboard identification number quantity,
Initial mainboard identification number corresponds to the identification number of memory information；If the identification number of memory information, which is more than reserved mainboard, identifies number
Measure, then initial mainboard identification number corresponds to the identification number of memory information and the difference of reserved mainboard identification number quantity, and BIOS chips enter
One step is configured as：When current flag value is 0, using initial mainboard identification number as mainboard identification number；Current flag value most 1
When, current flag value is placed in initial mainboard identification number highest order and obtains mainboard identification number.
According to Fig. 2 control device 200, EC is configured to：By to it when starting from current power-on self-test
During the stand-by period of watchdog circuit setting, change current flag value, when the stand-by period is more than the conventional power-on self-test of computer
Between.
The concrete operations of various pieces in Fig. 2 device correspond to Fig. 1 method, and this is repeated no more.
