AT&T 2.1.1 manual Configuration the Setup Utility, Hard disk

Hardware Installation

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 configuration 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

■the amount of memory is changed

■the system’s clock/calendar battery fails or is replaced

The SETUP program can be run from a floppy disk or from the hard disk. The recommended way is to run the program from the hard disk. Run the SETUP program from a floppy disk if diagnostics are to be run. See the User's Guide for your processor to run the SETUP program from

a hard disk.
