Configuration: the Setup Utility
When you bring up the system after installing hardware, you must run
the setup utility to store the system configuration information in the
battery-backed CMOS memory. Until this information is stored,
the system will not operate properly.
Each time the system is turned on or reset, the Power-On Self Test (POST)
routine runs automatically and checks the CPU, keyboard, video display,
memory, and most peripheral devices. The POST routine checks the stored
setup information against the hardware configuration. If the stored
configurate ion does not agree with the hardware found, POST displays an
invalid configuration message.
You must run the setup utility whenever:
•
the POST routine indicates that the configuration is invalid or
specifically requests that the setup utility be run
•
any hardware component is added, changed or removed
•
amount of memory is changed
•
the system’s clock/calendar battery fails or is replaced
To run the setup program, follow these steps:
1 Insert the Customer Test disk supplied with the system into drive A.
2 Boot the system by turning power ON or by pressing the [Reset] button if
the system is already on.
The system boots from the Customer Test disk and displays the
Customer Test introduction screen.
3 Press [Enter] to continue.
The Customer Test main menu appears.
