HOW TO USE:

1.  Format a 1.44-MB diskette.

2.  Download the SoftPaq to a temporary, empty directory on your
    hard drive and change to that directory.  The file downloaded
    is a self-extracting executable with a filename based on the
    SoftPaq Number above.

3.  From that drive and directory, execute the SoftPaq file.
    You will be prompted to place the formatted 1.44 MB diskette
    into a diskette drive to create the ROMPaq diskette.

4.  After the diskette is created, you may delete the downloaded
    file if you wish.

5.  Shutdown and turn off the computer.  Wait 15 seconds.  Place the 
    ROMPaq diskette into drive A: and turn on the power, allowing the 
    computer to boot from the diskette.

6.  The ROMPaq diskette will automatically update the System ROM and 
    notify you when the update is finished.

    CAUTION:  DO NOT TURN OFF YOUR COMPUTER DURING THE UPDATE PROCESS

7.  When the ROM update is finished, you will need to turn the computer 
    off and back on for the changes to be in effect.  Remove the ROMPaq 
    diskette from the computer.  Turn the computer's power switch OFF, 
    wait 15 seconds, then turn the switch ON again.

8.  On the first boot after the update you will see this message:
    ERROR
    0251: System CMOS checksum bad - Default configuration used
    This is expected, since CMOS was set to a default state during the update.
    Press the "F1" key to boot the system.  You will not see this message on 
    subsequent boots.
