This invention belongs to the field of PCIe device technology, specifically providing a method, apparatus, device, and medium for automatically adjusting transmitter balance values. The method includes the following steps: When the BIOS starts PCIe link training, it iterates and checks whether there are any PCIe devices connected to the PCIe root ports on the CPU side; when a PCIe device is detected, pre-write values ​​to the secondary bus register and auxiliary bus register of each PCIe root port; read the manufacturer code and device code of the PCIe device connected to the secondary bus; compare the read manufacturer code and device code with the manufacturer code and device code of the PCIe device whose transmitter balance value needs to be adjusted; when the comparison results match, call the write function to write the transmitter balance value and make the written transmitter balance value effective. This can save testing, production, and maintenance time.
