[0020] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.
[0021] S101: Read the system file corresponding to the P list through the serial port, and the P list is in the position corresponding to the head 0, volume 3, and file descriptor of the hard disk;
[0022] S102: Analyze the effective data body of the P list to distinguish abnormal entries;
[0023] S103: Clear all abnormal entries;
[0024] S104: Starting from the offset position of the effective data body of the P table, take 14 bytes as a group, and use the two groups of bytes as the unit to first sum, and then calculate the modulus; loop until the end of the effective data body of the P table, and calculate The result is written into the last 2 bytes of the P table to cover;
[0025] The specific algorithm is as follows:
[0026]
[0027]
[0028] S105: Perform compiler reconstruction on ...
