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.
ICH Fixed I/O Registers
To clear and reset the configuration, perform the following procedure:
Port Register Name 1. Prepare the computer for disassembly.
00h, 02h, 04h, 06h Channel 0, 1, 2, 3 DMA base and current address register
CAUTION: The power cord must be disconnected from the power source before pushing the Clear CMOS
C0h, C4h, C8h, CCh Channel 4, 5, 6, 7 DMA base and current address register Button (NOTE: All LEDs on the board should be OFF). Failure to do so may damage the system board
2. Remove the access panel.
01h, 03h, 05h, 07h Channel 0, 1, 2, 3 DMA base and current count register
3. Press the CMOS button located on the system board and keep it depressed for 5 seconds.
C2h, C6h, Cah, CEh Channel 4, 5, 6, 7 DMA base and current count register
4. Replace the access panel.
10h-1Fh Aliased at 00h-0Fh
5. Turn the computer on and run F10 Computer Setup (delete-utility) to reconfigure the system.

24h,-25h, 28-29h, 2Ch-2Dh, 30h- Aliased at 20h-21h
1. Turn off the computer and any external devices, and disconnect the power cord from the power outlet.

4. Remove the jumper from pins 1 and 2. Place the jumper over pin 2 only, in order to avoid losing it.
41h Counter 1 interval time status byte format and Counter 1 counter access port regis-
5. Replace the access panel.

6. Plug in the computer and turn on power. Allow the operating system to start. (Placing the jumper on pin 2 clears the
42h Counter 2 interval time status byte format and Counter 2 counter access port regis-
current passwords and disables the password features.)

7. To re-enable the password features, repeat steps 1-3, then replace the jumper on pins 1 and 2.
43h Timer control word register, Timer control word register read back, and Counter
8. Repeat steps 5-6, then establish new passwords.
