When the computer is turned on, it cannot be self-inspected, prompting the BIOS version, the following prompt is "ROM BIOS Checksum Error" and then prompt to insert "System Disk". This phenomenon is a protection function taken when certain motherboards are destroyed by BIOS. The above suggests is actually the bootblock in this motherboard BIOS work, the purpose is to require the correct BIOS file to repair damaged information, not the system boot disk. At this time, the correct way to operate should be: Insert the floppy disk with the motherboard Bios file that you purchase, then press the Enter key, and the system will automatically read and complete the refresh. After such an operation, the problem can be solved. If there is no floppy of the BIOS file included with the motherboard, you can download these files into a floppy disk from the manufacturer to a floppy disk (such as awdflash.exe), and the system will automatically call the burn software. Then select the corresponding BIOS file (such as C133A.bin), etc. When the sink is complete, it will be automatically restarted. Do not cut off the power or restart during the burn. Note: Checksum is a simple and easy integrity control method in the field of data processing and data communication. Combine all bytes of the data through a series of arithmetic or logical operations to get a checksum value. The checksum values can be calculated by the same method and compared to the value calculated last time. If the phase is equal, the data has not changed; if it is not equal, the data has been modified.
