Abstract

The invention provides a system and a method for identifying information of peripheral component interface devices. The method comprises steps of: initializing an address argument and an address shift value; writing a first address to a configuration port; reading data from a data port; judging on the PCI bus whether has corresponding PCI devices according to the data; writing a second address value to the configuration port if the corresponding device exists; reading PCI device information from the data port; adding 1 to the address shift value; judging whether the address shift value is less than 64; reading all information of the PCI device if the address shift value is less than 64; judging whether all PCI devices have been identified; reading and displaying all PCI device information if all PCI devices have been identified.

Description

【Technical field】

[0001] The present invention relates to a system and method for identifying information of computer equipment, in particular to a system and method for identifying information of interconnection equipment of peripheral components. 【Background technique】

[0002] In the field of microcomputers, mainly Intel Corporation has introduced the specification of the computer peripheral component interconnection (Peripheral Component Interface, PCI) bus. This specification adopts the configuration space of PCI equipment and the technology that the PCI bus is connected to the microprocessor through a bridge circuit, which makes the PCI bus widely adaptable; and the PCI bus adopts a wide byte and a clock frequency up to 66Mb / Sec and a master Control mode transmission to meet the requirements of high-speed equipment. Therefore, the PCI bus can support multiple peripheral devices at the same time, such as graphics card, sound card, network card, built-in ADSL, USB card,...
