As one embodiment, the method further comprises: and acquiring and storing a signal distribution result based on the initial BIOS configuration interface.
It can be understood that, after the computer device displays the initial BIOS configuration interface, the initial BIOS configuration interface has an Auto Detect Result option, the Auto Detect Result option is triggered, a primary signal distribution Result of primary signal distribution to the PCIe lanes according to a preset signal distribution table may be displayed, and the primary signal distribution Result may be stored in a computer storage medium, so as to be used in a subsequent implementation of secondary signal distribution.

S3320, performing secondary signal distribution on the PCIe channel according to the secondary signal distribution table.
It should be noted that, the computer device may perform secondary signal distribution on the PCIe lanes according to the setting information stored in the secondary signal distribution table.
The signal distribution method can set the secondary signal distribution table corresponding to the selected target distribution option on the basis of primary signal distribution so as to realize the secondary signal distribution mode of actual requirements according to the secondary signal distribution table, and avoid the situation that secondary signal distribution processing can be realized only by BIOS engineers modifying BIOS codes, thereby simplifying the operation flow of signal distribution processing, reducing the complexity of signal distribution processing and further shortening the time of signal distribution processing.
As an embodiment, the step of setting the corresponding secondary signal allocation table according to the target allocation option in S3310 may specifically include: and setting the use state of each PCIe channel according to the number of PCIe channels corresponding to the target distribution option to obtain the secondary signal distribution table.
Specifically, the computer device may set the use state of each PCIe channel according to the number of PCIe channels corresponding to the selected target allocation option, so as to obtain the secondary signal allocation table. If the selected target allocation option is 1 × 8, there are 16 PCIe lanes, that is, PCIe lanes 0 to PCIe lanes 15, at this time, the setting information stored in the secondary signal allocation table may include that the use states of the 8 PCIe lanes from PCIe lane 0 to PCIe lane 7 are set to Enable state Enable, and the use states of the 8 PCIe lanes from PCIe lane 8 to PCIe lane 15 are set to Disable state Disable, so in the actual execution process, the use states of PCIe lanes 0 to PCIe lane 7 are set to Enable state, and the use states of PCIe lanes 8 to PCIe lane 15 are set to Disable state, so as to achieve the purpose of secondary signal allocation.
The signal distribution method can set the use state of each PCIe channel according to the number of the PCIe channels corresponding to the target distribution option on the basis of primary signal distribution to obtain a secondary signal distribution table, and further realize secondary signal distribution according to the setting information in the secondary signal distribution table.
