[. . . ] 1 Electronic Emission Notices Federal Communications Commission (FCC) Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with instructions contained in this manual, may cause harmful interference to radio and television communications. However, there is no guarantee that interference will not occur in a particular installation. [. . . ] When the system is turned on the first time or the CPU is changed, a Pentium II-133 or -200 (depends on the CPU bus speed) will be recognized and a warning message of "CPU has been changed" will appear. Please enter the CMOS setup menu to configure the CPU speed.

The board has DIMM sockets arranged as banks 1, and 2. You can install DIMMs in any of the two banks, and use different size DIMMs in different banks. The BIOS detects the size and type of installed memory. Installing the Retention Mechanism for Intel® Pentium® II & Intel® Pentium® III or Intel® Celeron® Processor To install the retention mechanism, follow these steps: 1. Locate Slot 1 and the four attachment holes on the motherboard. To position the mechanism, orient it as shown in figure. The tab on the connector fits into a notch in the base of the mechanism. Press down on the studs until it is firmly seated in attachment holes. The BIOS reads the system information contained in the CMOS and begins the process of checking out the system and configuring it. When it finishes, the BIOS will seek an operating system on one of the disks and then launch and turn control over to the operating system . While the BIOS is in control, the Setup Program can be activated: 1. By pressing <Del> immediately after switching the system on, or 2. By pressing the <Del> key when the following message appears briefly at the bottom of the screen during the POST (Power On Self Test ) Press DEL to enter SETUP If the message disappears before you can respond and you still wish to enter Setup, restart the system to try again by turning it OFF then ON or pressing the "RESET" button on the system case. You may also restart by simultaneously pressing the <Ctrl>, <Alt>, and <Delete> keys. If you do not press the keys at the correct time and the system does not reset, an error message will be displayed and you will again be asked to . . . PRESS F1 TO CONTINUE, DEL TO ENTER SETUP Getting Help Press F1 to pop up a small help window that describes the appropriate keys to use and the possible selections for the highlighted item.
