In steps S11 and S13, the basic input output system 11 reads external files from the external file database 13 and retrieves chip information from the chip 5. In particular, it should be noted that the sequence of steps S11 and S13 in FIG. 3 is only shown as an example. In other embodiments, the basic input output system 11 may first capture chip information and then read external files. Two data can be read at the same time. In step S15, the BIOS 11 executes the chip identification process according to the external file and the chip information to obtain the chip identification result. Furthermore, the result of the wafer identification process can define which attribute the wafer 5 belongs to. In step S17, the basic input output system 11 will configure the universal input output port 211 according to the chip identification result. Furthermore, the basic input/output system 11 can set the function and/or state (for example, the level of potential) of each pin of the universal input/output port 211 according to the chip identification result, so that the universal input/output port 211 matches the chip 5.

The wafer identification process of step S15 is described in detail, which may include steps S151 to S157 of FIG. 4. As mentioned above, the external files stored in the external file database 13 may include multiple chip series data, the multiple chip series data including multiple chip section data, and the multiple chip section data include multiple The device identification code data is similar to the concept of storing multiple device identification code data in a multi-layered folder, and each of the multiple device identification code data includes a corresponding device identification code name. In step S151, the basic input output system 11 determines that the chip information belongs to one of the plurality of chip series data, and one of these is used as the discriminating chip series data. In step S153, the basic input output system 11 determines that the chip information belongs to one of the plurality of chip segment data in the discriminating chip series data obtained in step S151, and uses one of them as the discriminating chip segment data. In detail, the basic input output system 11 will be the device and manufacturer identification code (ID) in the PCIE configuration setting space of the multi-function input/output (I/O) controller that supports the ISA device bus in the chip information. The information is compared with multiple chip section data in the discriminant chip series data to determine the discriminant chip section data to which the chip information belongs. In step S155, the basic input output system 11 determines that the chip information belongs to one of the multiple device identification code data in the identification chip section data obtained in step S153, and uses one of them as the identification device identification Code information. In step S157, the basic input output system 11 obtains the identification device identification code data obtained in step S155 and the corresponding device identification code name as the chip identification result.

As described in step S17 of FIG. 3 above, the basic input output system 11 will configure the universal input output port 211 according to the chip identification result. In one embodiment, each device identification code data in the external file includes pin information of the universal input and output port 211, and the pin information includes control pin start data and control pin interval data.

In step S171, the basic input output system 11 obtains the control pin start data and the control pin interval data corresponding to the chip identification result. In step S173, the basic input/output system 11 selects the pin corresponding to the initial data of the control pin in the universal input/output port 211, and starts to configure the pin (for example, set its potential level). After the pins selected in step S173 are configured, in step S175, the basic input output system 11 selects the next pin to be configured according to the control pin interval data. For example, when the control pin start data indicates that the configuration starts from the 3rd pin and the control pin interval data indicates the interval of 2 pins, the basic input output system 11 will select the general input and output port 211 from the first Start to configure the 3 pins, and continue to configure the 5th and 7th pins at intervals of 2, and so on and repeat the configuration until the serial number of the pins reaches the total number of pins set by the external file, that is, external The total number of pins set in the file is used as the stop condition. The present invention does not limit the pin parameter values actually indicated by the control pin start data and the control pin interval data.

In the conventional general-purpose I/O port configuration method, the configuration of each pin has been pre-written in the program that executes the configuration method, which means that for various platforms (chips), the conventional general-purpose I/O ports The configuration method must design multiple configuration programs to respond to the various platforms. In contrast, one or more embodiments of the present invention separate the configuration program from the pin information that changes due to different platforms, and design a general main program to execute the process of chip identification and pin configuration, and integrate various chips The structure information and its pin information are stored as external files, thereby reducing the storage space occupied by the configuration program in the computer device, and can efficiently switch between platforms of different specifications.

In step S22, the basic input output system 11 retrieves chip information from the chip 5. Among them, the chip information can include bus data, equipment data, and function data. In this embodiment, the basic input output system 11 can retrieve the chip information of the chip 5 through the main program 113, and store it in the memory 215, and then read the chip information in the memory 215 in step S23, according to The obtained external files and chip information are used for the subsequent chip identification process, including steps S24 to S26.

In step S24, the basic input output system 11 searches and selects one of the multiple device identification code data in the external file. In step S25, the basic input output system 11 determines whether the selected device identification code data matches the chip information. Furthermore, the basic input output system 11 will determine whether the device ID data is the same as the device data in the chip information. When the judgment result is no, as shown in step S26, the basic input output system 11 will then judge whether the device ID data is the last device ID data in the external file that has not been selected. If not, the basic input output system 11 will execute the aforementioned steps S24 and S25 again, and select another device ID code data to compare with the chip information; if it is, it means that there is no data that meets the chip 5 specifications in the external file, and it ends Configuration process.

When the BIOS 11 determines in step S25 that the selected device ID code data matches the chip information, as shown in steps S27 and S28, the BIOS 11 defines the attributes of chip 5 and loads the corresponding pins of chip 5 Bit information. Furthermore, the basic input and output system 11 loads the pin information corresponding to the chip 5 into the register 213, so as to set the potential of each pin of the universal input/output port 211 through the register 213. The details are The pin setting method of is as described in the previous embodiment in FIG. 5, and will not be repeated here.

By storing the universal main program and external files in a computer device and an external database such as a cloud device, respectively, the configuration method and system for the universal input and output ports disclosed in this case do not need to store the complete control code corresponding to multiple platforms in In the computer device, the storage space occupied is reduced, and it can be efficiently switched between platforms of different specifications. In addition, when a new specification platform is released in the future, the configuration method and system of the universal input and output ports disclosed in this case only need to update the content of the external files, without the need to re-develop the overall control program of the universal input and output ports to achieve the development process.
