Explanation

IBM BIOS POST error codes use number ranges to indicate component failures: 1xx for system board, 2xx for memory (RAM), 3xx for keyboard, 4xx for monochrome display, 5xx for color display, and 6xx for floppy disk controller. A 3xx code specifically points to keyboard detection or communication issues during POST.
