[. . . ] It supports a jumper-less design that automatically detects the CPU voltage and frequency. If you made some changes in the CMOS settings (BIOS) and your system fails to boot, do the following: 1. Choose Load Setup Defaults to undo the changes you made and set the BIOS setup parameters to their original settings. 40 Chapter 3 Award BIOS Entering Setup To enter Setup, press Ctrl-Alt-Esc during the POST (Power-on self-test). The "BIOS Setup" main menu then appears: Note: Choose "Load Setup Defaults" for best performance with light system loading. Refer to "Load Setup Defaults" on page 61. The section at the bottom of the screen tells how to control the screen. Use the arrow keys to move between items, ESC to exit, and F10 to save the changes and exit. Another section at the bottom of the screen displays a brief description of the highlighted item. The grayed items on the screens have fixed settings and are not user-configurable. 41 Standard CMOS Setup The Standard CMOS Setup sets the basic system parameters such as the date, time, and the hard disk type. Use the arrow keys to highlight an item and PgUp or PgDn to select the value for each item. The table below describes each Standard CMOS Setup parameter. Settings in boldface are the default and suggested settings. Parameter Date Description Lets you set the date following the weekday-month-day-year format. Format/Options Weekday: Sun, Mon, Tue, Wed, Thu, Fri, Sat Month: Jan, Feb. . . Dec Day: 1 to 31 Year: 1980 to 2079 Time Lets you set the time following the hour-minute-second format. Hour: 0 to 23 Minute: 0 to 59 Second: 0 to 59 42 Chapter 3 Award BIOS Parameter Hard Disk Type Primary Master Primary Slave Secondary Master Secondary Slave Description This item lets you select the IDE hard disk parameters that your system supports. Auto enables BIOS to automatically detect the parameters of installed HDD during the POST (Power-on self-test). VGA BIOS Shadowing means to copy video display card BIOS into the DRAM area. This enhances system performance because DRAM access time is faster than ROM. Disabled Enabled OS Select for DRAM > 64MB Non-OS/2 OS/2 Video BIOS Shadow Enabled Disabled 48 Chapter 3 Award BIOS Parameter C800-CBFF Shadow CC00-CFFF Shadow D000-D3FF Shadow D400-D7FF Shadow D800-DBFF Shadow DC00-DFFF Shadow Description These six items are for shadowing ROM code on other expansion cards. Before you set these parameters, you need to know the specific addresses of that ROM code. If you do not know this information, enable all the ROM shadow settings. Format/Options Disabled Enabled 49 Chipset Features Setup Caution: Make sure you fully understand the items contained in this menu before you try to change anything. However, changing these parameters could make your system unstable if the setting is not correct for your system configuration. The table below describes the parameters found in this menu. Parameter Bank 0/1 DRAM Timing Bank 2/3 DRAM Timing Bank 4/5 DRAM Timing Description These items are used to set DRAM timing parameters which can be automatically set by BIOS. Options SDRAM 10ns SDRAM 8ns Normal Medium Fast Turbo SDRAM Cycle Length 3 2 50 Chapter 3 Award BIOS Parameter DRAM Clock Description Please refer to the table on page 51 to set the DRAM clock. Options CPU CLK CPU CLK +33 CPU CLK -33 Memory Hole This option lets you reserve system memory area for special ISA cards. The chipset accesses code/data of these areas from the ISA bus directly. Lets you configure the hard disk drive connected to the slave port of IDE channel 2. Enabling this item allows you to cache the system BIOS to further enhance system performance. If you are not sure which AGP mode to choose, simply select the highest AGP mode (4x) available. This item lets you determine the effective size of the AGP Graphic Aperture. [. . . ] Not turning off the system properly before you start installing the components may damage your system. Do not attempt the procedures described in the following sections unless you are a qualified service technician. Postinstallation Instructions Observe the following after installing a system component: 1.
