Note:
!
You should ALWAYS clear your CMOS after flashing a BIOS. This
will clear out any stray settings from your old BIOS which may have
been carried over from the flashing process. Most problems encoun-
tered after flashing a BIOS will be solved by this simple procedure.
To reprogram the System BIOS, you must first do the following:
1. Check jumper JP2 (default pins 1-2). The S1576S uses a 5V flash
EPROM, so jumper JP2 should be left in the default position on
pins 1 and 2. This jumper should never be moved, and has been
hardwired on some boards.
2. Make sure the CPU is running in "real mode." FMW will not run
if the CPU is operating in a protected or "virtual mode." This
means that you can not run it with Windows running or with any
memory manager software. You must disable any memory man-
ager before you can run FMW. The easiest way to do this is as
follows:
A. Boot your system from a bootable floppy disk with no
CONFIG.SYS or AUTOEXEC.BAT files, and then run
Flash Memory Writer from a backup copy of your support
disk. You can make your backup floppy bootable when
you format it, and use one disk for both purposes.
B. If you are using MS-DOS 6.x, you can use the feature that
allows you to bypass the CONFIG.SYS and
AUTOEXEC.BAT file. You can access this feature by
pressing <F5> while the "Starting MS DOS..." line is on
the screen.
It is important that you make sure that there are no memory managers
running. If you are uncertain whether or not there is a memory man-
ager running on your system, try running FMW. If it works, there is no
active memory manager. If you see a warning message about the CPU
mode, check to see that you have followed the preceding directions
properly, and try again.
