Lite-ON CD-ROM DU25 Firmware Update README This package performs a flash update of the firmware that controls the Lite-ON CD-ROM which might have come preinstalled in your IBM(R) Aptiva(R) computer. This update resolves several problems associated with the READ functions of the CD-ROM. NOTE: Firmware is programming that controls low-level hardware operations internal to the CD-ROM.
