* Insert valid ROMPaq diskette in drive A. Turn power switch off, then on to reflash ROM. If ROM flash is successful, all
three keyboard LEDs will light up, and you will hear a rising tone series of beeps. Remove diskette and turn power off,
then on to restart the computer. For more information about flashing the ROM, refer to the Troubleshooting guide.
Clearing CMOS
The computer's configuration (CMOS) may occasionally be corrupted. If it is, it is necessary to clear the CMOS
memory using switch SW50.
To clear and reset the configuration, perform the following procedure:
1. Prepare the computer for disassembly.

CAUTION: The power cord must be disconnected from the power source before pushing the Clear CMOS
Button (NOTE: All LEDs on the board should be OFF). Failure to do so may damage the system board
Remove the access panel.
Press the CMOS button located on the system board and keep it depressed for 5 seconds.
Replace the access panel.
Turn the computer on and run F10 Computer Setup (Setup-utility) to reconfigure the system.

Turn off the computer and any external devices, and disconnect the power cord from the power outlet.
Remove the access panel.
Locate the header and jumper labeled E49.
Remove the jumper from pins 1 and 2. Place the jumper over pin 2 only, in order to avoid losing it.
Replace the access panel.
Plug in the computer and turn on power. Allow the operating system to start.
NOTE: Placing the jumper on pin 2 clears the current passwords and disables the password features.
To re-enable the password features, repeat steps 1-3, then replace the jumper on pins 1 and 2.
Repeat steps 5-6, then establish new passwords.
Refer to the Computer Setup (F10 Setup) instructions to establish new passwords.
