To reprogram the System BIOS, you must first do the following:

1. Check jumper JP2.(Default pins 1-2)

The S1572 uses a 5V Flash EPROM so jumper JP2 should be left in the default postion on pins 1 and 2. This jumper should never be moved.

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 manager first. The easiest way to do this is to:

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 back-up 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 do this while pressing <F5> while the “Starting MS- DOS...” line is on the screen.

There are other ways to accomplish the same result. The main point is to make sure no memory managers are running. If you are not sure, try running FMW. If it runs, then you have suc- ceeded. If it displays a warning message about the CPU mode, you will have to try again.
