[. . . ] 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. [. . . ] - This motherboard is compatible with Cyrix 6x86 CPU, which must be Revision 2. 7 or newer. Please contact your CPU supplier for details on identification of Cyrix 6x86 CPU revisions. - This motherboard can be run with cyrix 6x86-P200+ CPU specifications of all add on cards. If system does not behave reliably at 75MHz Bus Clock, you should set the Bus Clock to 50MHz (JP3 set "2-3", JP4 set "2-3" JP5 set "1-2"). - * = Default setting.

Technical Reference Booklet JP31 JP25 JP26 JP27 JP28 JP37 JP36 9 Memory Configuration The table 1 and table 2 shows the possible memory combinations. Positioning the CPU incorrectly in the socket can permanently damage the CPU and the computer when you turn on the system. Technical Reference Booklet 11 BIOS SETUP This chapter discusses Award's Setup Program built into the ROM BIOS. The Setup Program allows users to modify the basic system configuration. This special information is then stored in battery-backed RAM, which retains the setup information when the power is turned off. Starting Setup The Award BIOS is immediately activated when you turn on the computer. 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. To exit the Help Window press <Esc> or the F1 key again. In Case of Problems If, after making and saving system changes with the Setup Program, you discover that your computer does not reset, use the Award BIOS defaults to override the CMOS settings. Main Menu Once you enter the Award BIOS CMOS Setup Utility, the Main Menu will appear on the screen. The Main Menu allows you to select from various setup functions and two exit choices. Use the arrow keys to select among the items and press <Enter> to accept and enter the sub-menu. BIOS Setup 12 ROM PCI/ISA BIOS CMOS SETUP UTILITY AWARD SOFTWARE. [. . . ] When you select this function, the following message will appear at the center of the screen to assist you in creating a password. ENTER PASSWORD: Type the password, up to eight characters in length, and press<Enter>. The new password will clear the previously entered password from the CMOS memory . You will be asked to confirm the password. Type the password again and press <Enter>. [. . . ]
