The notebook’s BIOS IC cannot be replaced separately. If it is defective, you must replace the motherboard. In some cases, however, you might be able to reprogram a malfunctioning BIOS IC using either e-DiagTools for Windows, a BIOS floppy disk, or a Crisis Recovery floppy disk. If the notebook will boot sufficiently, use e-DiagTools for Windows or a BIOS floppy disk to reprogram the BIOS IC. If you cannot boot the notebook adequately, use a Crisis Recovery floppy disk. See below for instructions for all three methods.
