Restoring The Default Cmos Settings; Clearing The Cmos Settings; Cmos Recovery; Real-Time Clock And Cmos - IBM Models 5 Service Manual

Diagnosing problems and troubleshooting
PC Health Status
This is an information window that provides the CPU and system temperatures,
voltages on the system board, and fan speed.
Load Defaults
This selection resets all options to their default configuration.
Set Password
Use the password options menu to set, change, or clear the system password.
TPM Configuration
The TPM configuration enables the TPM Security module.

Restoring the default CMOS settings

To restore CMOS default settings, select Load Optimized Settings from the main
menu.

Clearing the CMOS settings

The AnyPlace Kiosk uses battery-backed CMOS memory to store system settings. If
the CMOS memory becomes corrupted and the system does not boot, you can
restore the factory default values by following the steps described in "Locating and
resetting the CMOS jumper" on page 48.

CMOS recovery

If the CMOS memory becomes corrupted and the system does not boot, restore the
factory default values by following the procedure described in "Clearing the
CMOS settings."
Always reset CMOS (as described at "Restoring the default CMOS settings") before
replacing a system board to resolve a problem. This practice allows you to
determine if a corrupted CMOS is the source of the trouble. A corrupted CMOS
can cause unpredictable problems.

Real-time clock and CMOS

The real-time clock is a low-power clock that provides a time-of-day clock and a
calendar. The clock settings are maintained by the battery when the power cord is
removed. Use the CMOS Setup Utility to set the clock and calendar. See "Standard
CMOS features" on page 69.
See "Changing the battery" on page 51 for the steps on replacing the battery.

Configuring the COM (communication) ports

Each COM port of the AnyPlace Kiosk is assigned a unique I/O address and IRQ.
The system BIOS configures the COM ports for use by the operating system;
therefore, a separate driver is not required.
Use the CMOS Setup Utility to configure the default I/O address and the IRQ. If
you make modifications, ensure that each port uses a unique I/O and IRQ value.
Using default values is highly recommended.
