(Default; Alternate = DMA 0) 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:
1. Prepare the computer for disassembly.
Port Register Name
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
Button (NOTE: All LEDs on the board should be OFF). Failure to do so may damage the system board
C0h, C4h, C8h, CCh Channel 4, 5, 6, 7 DMA base and current address register
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.
5. Turn the computer on and run F10 Computer Setup (delete-utility) to reconfigure the system.

register 3. Locate the header and jumper labeled E49.
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
register 5. Replace the access panel.
42h Counter 2 interval time status byte format and Counter 2 counter access port 6. Plug in the computer and turn on power. Allow the operating system to start.

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
latch command 8. Repeat steps 5-6, then establish new passwords.
50h-53h Aliased at 40h-43h
Refer to the Computer Setup (F10 Setup) instructions to establish new passwords.
61h NMI status and control register
*When the CMOS button is pushed or the jumper is removed, both the power-on password and the setup password
70h NMI enable register and Real-time clock (Standard RAM) index register
become invalid because both are stored in the configuration memory. You will need to reset the passwords.
