Abstract
A method for automatically configuring a PCIe slot comprises: writing a configuration value into a storage device, with the configuration value associated with a configuration manner of the PCIE slot, reading the configuration value from the storage device by a BIOS, and determining whether the configuration value belongs to a valid value set, the BIOS configures a data bandwidth of the PCIe slot according to the configuration value when the configuration value belongs to a valid value set, and the BIOS configures the data bandwidth of the PCIe slot according to a default value when the configuration values does not belong to the valid value set.
Claims10
A method for automatically configuring PCIe slot, comprising:
- writing a configuration value into a storage device, with the configuration value associated with a configuration manner of a PCIe slot;
- by a BIOS, reading the configuration value of the storage device;
- by the BIOS, determining whether the configuration value is valid by determining whether the configuration value belongs to a valid value set;
- by the BIOS, configuring a data bandwidth of the PCIe slot according to the configuration value when the configuration value belongs to the valid value set;
- and
- by the BIOS, configuring the data bandwidth of the PCIe slot according to a default value when the configuration value does not belong to the valid value set.
A computer program product stored in a non-transitory computer-readable storage medium, for a BIOS of a computer to automatically configure a PCIe slot when the computer program product is executed by the computer, comprising:
- a reading process driving the BIOS to read a configuration value from a storage device, with the configuration value used to configure a data bandwidth of the PCIe slot;
- a determining process driving the BIOS to examine whether the configuration value belongs to a valid value set;
- and
- a configuration driving the BIOS to selectively configure the data bandwidth of the PCIe slot by the configuration value or by a default value according to an examination result of the determining process.
