48X CD-ROM drive firmware update version 1.0 Installation README This package performs a flash update of the firmware that controls the 48X CD-ROM drive which might have come preinstalled in your IBM(R) computer. A blank 1.44MB 3.5 inch diskette will be needed. NOTE: Firmware is programming that controls low-level hardware operations internal to the CD-ROM. The firmware is stored on a chip. Your CD-ROM uses flash ROM's, which can be updated through a program on a flash diskette so that you do not have to replace the firmware chip to update the firmware.
