To correct these errors, run the Setup Utility and select Load Optimized Defaults. This restores the CMOS defaults. After the defaults are restored, check the date and time, and set any other customer-specific settings that were modified before the CMOS was reset. 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 14. See "System-board battery - removing and replacing" on page 51 for the location of the battery. Configuring the COM (communication) ports Each COM port of the 4846 product uses a unique I/O address and IRQ. Some previous SurePOS 500 system units utilized PCI-based COM ports with a shared IRQ. The system BIOS configures the COM ports for use by the operating system; therefore, a separate driver is not required. (Serial port drivers from previous SurePOS 500 systems are not supported or required.) Use the CMOS Setup Utility to configure or modify the COM ports, 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 are highly recommended. The IBM SurePOS 500 Series Operating System Installation Guide for Models 545 and 565 provides a list of port resources. Using the IBM Diagnostics for POS Systems and Peripherals package Diagnostics for the SurePOS 500 Models 545 and 565 are available on the IBM Diagnostics for POS Systems and Peripherals package. This package installs to a memory key (see "Supported memory keys" on page 17). Note: The Diagnostics also supports IBM POS I/O on prior systems, if the BIOS supports booting from a memory key. Locate the instructions for using this package in the README file. This package provides menu-driven tests and utilities that enable trained service technicians to configure and test the I/O devices. Locate and download the service program code from the IBM Retail Store Solutions Web site using the following steps: 1. Obtain a memory key. See "Supported memory keys" on page 17. 2. Access the IBM Retail Store Solutions Web site at: www.ibm.com/solutions/ retail/store/support. 3. Select Support on the left side of the panel, then select IBM SurePOS 500/600 Series. 4. Next, select SurePOS 500-xx5 Downloads. 5. Download the update program to a temporary location on the PC's hard-disk drive. Run the self-extracting program and respond to the messages that display. This program writes the updates and provides instructions on inserting the memory key. 16 Models 545 and 565 Hardware Service Guide

To
correct
these
errors,
run
the
Setup
Utility
and
select
Load
Optimized
Defaults
.
This
restores
the
CMOS
defaults.
After
the
defaults
are
restored,
check
the
date
and
time,
and
set
any
other
customer-specific
settings
that
were
modified
before
the
CMOS
was
reset.

settings
are

Configuring
the
COM
(communication)
ports
Each
COM
port
of
the
4846
product
uses
a
unique
I/O
address
and
IRQ.
Some
previous
SurePOS
500
system
units
utilized
PCI-based
COM
ports
with
a
shared
IRQ.
The
system
BIOS
configures
the
COM
ports
for
use
by
the
operating
system;
therefore,
a
separate
driver
is
not
required.
(Serial
port
drivers
from
previous
SurePOS
500
systems
are
not
supported
or
required.)
Use
the
CMOS
Setup
Utility
to
configure
or
modify
the
COM
ports,
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
are
highly
recommended.
