Before reprogramming the system BIOS, you must first do the follow-
ing:
1. Programming the ROM chip installed in the system requires that you
first enable programming as described on page 8 "Boot Block Pro-
gramming".
2. Make sure the system is running in real mode. This utility will not
operate if the system is under protected or virtual mode. This means
that you can not reprogram the system BIOS under the Windows envi-
ronment or with any memory management software, including
HIMEM.SYS. If you have any memory management software run-
ning, disable them first. The following describes the easiest way to
ensure that your system memory is free from these programs:
•
Boot from a floppy disk formatted with the "FORMAT A:/S" com-
mand without creating CONFIG.SYS and AUTOEXEC.BAT files.
•
If you are using MS-DOS 6.x, you can bypass the AUTOEXEC.BAT
and CONFIG.SYS by pressing
line is displayed on the screen.
•
For Windows 95 users, press
Startup Menu and then choose "Safe mode command prompt only"
Once you have accomplished the above tasks, you can run the Flash Memory
Writer utility. You can copy the contents of the \FLASH directory to your
hard disk drive or to a backup floppy disk. When copying the files, ensure
that the BIOS file is on the same directory as the utility. To run, change to
the directory containing PFLASH.EXE and then at the DOS prompt, type:
PFLASH
