Figure 2 As shown, the process includes the following steps:

[0037] Step S202, obtaining target device information of a target terminal device, wherein the target terminal device is connected to a processor in a computer system through a Retimer chip;

[0038] Step S204, searching for a target working mode of the Retimer chip corresponding to the target device information from a predetermined working mode table, wherein the working mode table includes a corresponding relationship between terminal devices and working modes of the Retimer chip;

[0039] Step S206, in a case where the target working mode does not match a current working mode of the Retimer chip, replacing the target working mode with the current working mode to instruct the Retimer chip to adjust signal quality of the target terminal device according to the target working mode.

[0040] The execution subject of the steps can be a Basic Input Output System (BIOS) or a device or system with terminal device detection capability, or other processing devices or processing units with similar processing capability, but is not limited thereto.

[0041] In the above embodiment, the determination manner of the working mode table includes, but is not limited to, a corresponding relationship between terminal devices and working modes determined through experimental test, a corresponding relationship determined according to terminal device models and Retimer chip working mode instructions, and the working mode table is stored in the BIOS after confirmation.

[0042] By pre-designing a corresponding table of working modes and terminal device information, the purpose of adjusting signal quality can be achieved in a case where the current mode is not a working mode matched with the terminal device. Therefore, the problem of low Retimer chip working mode switching efficiency in the related art can be solved, and the effect of improving Retimer chip working mode switching efficiency is achieved.

[0043] In an example embodiment, in the case that the target working mode does not match the current working mode of the Retimer chip, the target working mode is replaced by the current working mode, including: in the case that the target working mode does not match the current working mode of the Retimer chip, sending a first modification instruction to the Retimer chip through the I2C bus to instruct the Retimer chip to modify the current working mode in the register to the target working mode in response to the first modification instruction, wherein the register is disposed in the Retimer chip. In the above embodiment, the Retimer chip is instructed to complete the modification of the working mode in the register by sending a modification instruction to the Retimer chip, avoiding a redundant interaction process and effectively improving the efficiency of the Retimer chip in adjusting the working mode.

[0044] In an example embodiment, before the target working mode is replaced by the current working mode of the Retimer chip in the case that the target working mode does not match the current working mode of the Retimer chip, the method further includes: stalling the POST process of the computer system, wherein the POST process includes a detection process of a motherboard in the computer system, and the Retimer chip is disposed in the computer system.

In the example embodiment, the initial working mode includes a mode in which the processor accesses the basic information of the terminal device and the working state of the Retimer chip does not affect the communication effect. By accessing the terminal device in the initial working mode, the adjustment of the working mode of the Retimer chip can be completed at the same time as the acquisition of the terminal device information, effectively improving the adjustment efficiency of the working mode of the Retimer chip.

[0048] In one exemplary embodiment, before acquiring the target device information of the target terminal device, the method further includes: training the PCIe link when it is determined that the computer system is powered on and the Retimer chip is in its initial operating mode; and establishing a connection between the Retimer chip and the processor through the trained PCIe link. In the above embodiment, by retraining the PCIe link, the connection between the Retimer chip and the processor is established, and the modified Retimer chip operating mode is applied in real time, effectively improving the efficiency of the Retimer chip's operating mode adjustment.
