Device and method for reading and writing nonvolatile memory of network card on line

Abstract

The invention discloses a device and a method for reading and writing a nonvolatile memory of a network card on line. The disclosed device comprises a human-computer interaction unit, a central processing unit, a kernel driving unit and a network card nonvolatile memory, wherein the kernel driving unit and the central processing unit carry out information interaction to read and write the network card nonvolatile memory; the human-computer interaction unit provides a user interface, and a user inputs an operation command; the central processing unit is used for obtaining the operation command and carrying out information interaction with the kernel driving unit; the central processing unit comprises a memory and a refreshing unit, wherein the refreshing unit reads a file which needs to be written into the memory and reads the physical address of a network card and the memory byte position of the physical address of the network card; and the physical address of the network card is used for replacing the contents of the corresponding byte position in the physical address of the network card, a check code is calculated, and storage media in the memory is sent to the kernel driving unit. Under a situation that the physical address, which is set by a system previously, of the network card is retained, the nonvolatile memory can be burnt on line.

Description

Technical field [0001] The present invention relates to the technical field of computer hardware, in particular to a device and method for online reading and writing of non-volatile memory of a network card. Background technique [0002] In the development of non-volatile storage media, the emerging non-volatile memory is gradually becoming an alternative product for volatile memory. Among various non-volatile memory products, it has the advantage that data can be stored, read, and deleted multiple times, and the stored data will not disappear after power failure. It has become a personal computer and electronic A memory component widely used in equipment. [0003] Under the Feiteng platform, network card equipment is generally equipped. When debugging network card equipment, it is sometimes necessary to update the non-volatile memory data of the network card equipment while retaining the physical address of the network card previously set by the system. The original scheme was t...
