Example 1:
FIG. 1 is a schematic flow diagram of a method of one embodiment of the invention. The execution subject of the method 100 may be the BIOS of the server to be initialized with the TCM/TPM chip.

Optionally, in step 1302, if it is determined that the original parameter information is consistent with the parameter information to be configured, step 1304 is executed: the chip initialization is finished.
Optionally, in step 120, according to the index code, code indexing is performed on the pre-established security chip configuration file to find the reference value of each relevant configuration information on the TPM/TCM working line in the server, which specifically includes:
assigning the index code to X; x is a preset variable;
and finding out each relevant configuration information on the working line of the corresponding reference security chip corresponding to the X value stored in the security chip configuration file.
Optionally, in step 110, the IPMI instruction calls the BMC to read the pull-up and pull-down resistance codes of the TPM/TCM from the TPM/TCM board.
For the convenience of understanding the present invention, the principle of the initialization method of the TPM and TCM universal server chip according to the present invention is taken as an example to initialize the configuration information of the first TPM (hereinafter referred to as "target TPM") (the TPM/TCM in other servers is also applicable), and the initialization method of the TPM and TCM universal server chip according to the present invention is further described below.
Specifically, the initialization method of the TPM and TCM universal server chip includes:
step S1: when the TPM/TCM is set in the BIOS initialization server, the BMC is called to read the pull-up and pull-down resistance codes of the TPM/TCM from the TPM/TCM board card and record the pull-up and pull-down resistance codes as index codes.
And powering on the server A, when the BIOS initializes the target TPM, sending a query instruction to the BMC through the IPMI instruction by the BIOS, and reading a pull-down resistance code of the target TPM from a target TPM board card (namely, a board card where the target TPM is located) through the BMC.
The pull-down resistance code read to the target TPM in this embodiment is a code G.
It should be noted that, in the server, each TPM/TCM is provided with a pull-up/pull-down resistor code, which is stored on the board where the TPM/TCM is located, and which is used to distinguish different TPMs and/or TCMs. The pull-up and pull-down resistor coding in this embodiment adopts binary coding, and each bit number in the coding represents a predefined code of a pull-up resistor or a pull-down resistor, where for each bit number in the coding: "0" indicates the code of its corresponding pull-down resistor, and "1" indicates the code of its corresponding pull-up resistor.
Step S2: and according to the index codes, carrying out code index on the pre-established security chip configuration file, finding out the reference value of each relevant configuration information on the TPM/TCM working line in the server, and recording as the parameter information to be configured.
In this embodiment, the security chip configuration file pre-established is a security chip configuration file F. The working circuit of the target TPM in the server and the working circuits of all the reference security chips in the security chip configuration file F are SPI buses.
For the server a, the security chip configuration file F is pre-configured with 5 (the number of which can be increased or decreased according to the actual situation) pieces of relevant configuration information on the working lines of different reference security chips, and the configuration information on the working lines of the reference security chips includes a pull-down resistance coding reference value corresponding to the reference security chip and an operating frequency reference value corresponding to the reference security chip.
The pull-up and pull-down resistance coding reference values of the 5 different reference safety chips are respectively as follows: code K1, code K2, code K3, code K4 and code K5. The code K5, the code K1, the code K2, the code K3 and the code K4 are different. In this embodiment, the code K1 is the same as the code G.
In order to ensure that the initialization work is performed normally, when configuring the security chip configuration file, a person skilled in the art can configure as many frequently used reference security chips as possible in the security chip configuration file in advance according to actual conditions or experience on the premise of meeting the initialization requirement, so as to increase the application range of the method 100.
Further, in order to ensure the normal operation of the initialization operation, a person skilled in the art may regularly maintain the security chip configuration file according to the actual situation.
In this embodiment, the BIOS performs code indexing on the security chip configuration file F according to the code M, finds a reference value of each piece of relevant configuration information on a working line of a target TPM in the server, and records the reference value as the to-be-configured parameter information H.
In this embodiment, the BIOS performs code indexing on the pre-established security chip configuration file according to the code M to find out each piece of relevant configuration information on the working line of the target TPM, which specifically includes:
a step L1 of assigning said code G to X; x is a preset variable;
l2, finding out each piece of relevant configuration information on the working line of the reference security chip corresponding to the value of X in the security chip configuration file, that is, finding out each piece of relevant configuration information on the working line of the reference security chip corresponding to the code K1 stored in the security chip configuration file, where the found out each piece of relevant configuration information is the parameter information H to be configured.
Before the step L1 is executed, the following settings may be performed in advance in the BIOS, so as to facilitate the step L2 to find out each piece of relevant configuration information on the working line of the reference security chip corresponding to the value of X in the security chip configuration file:
when X is the code K5, finding out the relevant configuration information on the working circuit of the reference security chip corresponding to the code K5 in the security chip configuration file;
when X is the code K4, finding out the relevant configuration information on the working circuit of the reference security chip corresponding to the code K4 in the security chip configuration file;
when X is the code K3, finding out the relevant configuration information on the working circuit of the reference security chip corresponding to the code K3 in the security chip configuration file;
when X is the code K2, finding out each relevant configuration information on the working circuit of the reference security chip corresponding to the code K2 in the security chip configuration file;
when X is equal to the code K1, the relevant configuration information on the working line of the reference security chip corresponding to the code K1 in the security chip configuration file is found out.
The use of variable X speeds up the execution rate to some extent.
Step S3 is then performed.
Step S3: and initializing corresponding parameters in the ME firmware of the server by using the found parameter information to be configured. The step S3 specifically includes:
step S31, reading each relevant configuration information on the working line of the target TPM stored in the ME firmware in the server A, and recording as original parameter information 1;
step S32, determining whether the original parameter information 1 is consistent with the parameter information H to be configured:
if yes, go to step S34;
if not, updating the original parameter information 1 in the ME firmware with the parameter information H to be configured, and then executing step S33.
And step S33, restarting the server system of the server A.
In this embodiment, after the step S33 is completed, the step S34 is continuously executed.
Step S34: the target TPM initialization ends.
In summary, the method 100 avoids the BIOS refresh for the TCM/TPM, saves time and labor, is convenient to use, and increases convenience for initializing each relevant parameter on the TPM/TCM working line in the server.
