[. . . ] PROPRIETARY NOTICE AND LIABILITY DISCLAIMER The information disclosed in this document, including all designs and related materials, is the valuable property of NEC Corporation (NEC) and/or its licensors. NEC and/or its licensors, as appropriate, reserve all patent, copyright and other proprietary rights to this document, including all design, manufacturing, reproduction, use, and sales rights thereto, except to the extent said rights are expressly granted to others. The NEC product(s) discussed in this document are warranted in accordance with the terms of the Warranty Statement accompanying each product. However, actual performance of each such product is dependent upon factors such as system configuration, customer data, and operator control. [. . . ] The computer will automatically adjust the memory size. NOTE: If the notebook has been configured for save-to-disk, it may be necessary to run PHDisk to re-partition the drive. The save-to-disk partition must be of a size sufficient to store the content of the whole memory size. SYSTEM BIOS UPGRADE PROCEDURE The NEC Versa 2400 Series supports the EPROM Flash BIOS that allows you to easily update the system BIOS using the Flash Programming utility program called "PHLASH. COM & PLATFORM. BIN". Update the system BIOS whenever you are upgrading the LCD Panel or adding modifications to the computer's hardware function. Copy the PHLASH. COM & PLATFORM. BIN BIOS utility program and the BIOS ROM file to the hard disk subdirectory. You can also choose to run the program from the floppy diskette. 2. Disable EMM386 or other memory manager programs before restarting the com- puter. When booting the DOS, press F5 to bypass the CONFIG. SYS and AUTOEXEC. BAT. You may also choose to boot from Drive A: with a clean DOS diskette. 3. At the DOS prompt, type "PHLASH <BIOSfilename. ROM>" to activate Flash BIOS programming utility. The computer will then prompt you again before starting to update the system BIOS. After programming is complete, the system will prompt you to reboot the computer to activate the new system BIOS.
