[. . . ] 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). If you prefer to enter HDD parameters manually, select User. Select None if no HDD is connected to the system. The IDE CD-ROM is always automatically detected. Format/Options Auto User None Hard Disk Mode Primary Master Primary Slave Secondary Master Secondary Slave This enhanced IDE feature allows the system to use a hard disk with a capacity of more than 528MB. This is made possible through Logical Block Address (LBA) mode translation. LBA is now considered a standard feature of current IDE hard disks on the market because of its capability to support capacities larger than 528MB. Note that if your HDD is formatted with LBA On, it will not be able to boot with LBA Off. Allows you to configure your floppy drive A. Auto Normal LBA Large Drive A 1. 44 MB, 3. 5-inch None 360 KB, 5. 25-inch 1. 2 MB, 5. 25-inch 720 KB, 3. 5-inch 2. 88 MB, 3. 5-inch 43 Parameter Drive B Description Allows you to configure your floppy drive B. Format/Options None 360 KB, 5. 25-inch 1. 2 MB, 5. 25-inch 720 KB, 3. 5-inch 1. 44 MB, 3. 5-inch 2. 88 MB, 3. 5-inch Both Drive A Drive B Disabled Floppy 3 Mode Support Allows your floppy drive(s) to run in 3 modes including 2. 88 MB mode. Video This item specifies the type of video card in use. Since current PCs use VGA only, this function is almost useless and may be disregarded in the future. This is useful only when two display cards use the same palette address and are plugged into the PCI bus at the same time (such as MPEQ or Video capture). In such case, the PCI VGA is silent while the MPEQ/Video capture is set to function normally. Set to OS/2 if your system is utilizing an OS/2 operating system and has a memory size of more than 64 MB. 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. You may change the parameter settings to improve system performance. 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. Settings in boldface are the default and suggested settings. 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. [. . . ] Align the cover's hinges to the housing frame and then gently push it in. Follow steps 1 and 2 to replace the other side. 77 Installing Additional Memory The three 168-pin sockets onboard support SDRAM-type DIMMs. You may install 32-MB, 64-MB, or 128-MB (single and double density) DIMMs for a maximum of 384-MB system memory. The SDRAM DIMMs should work under 3. 3 volts only; 5-volt memory devices are not supported. [. . . ]
