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.

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 parameter enables you to control the system stops in case of Power-on self-test (POST) errors. EGA/VGA CGA40 CGA80 Mono Halt On All Errors No Errors All, But Keyboard All, But Diskette All, But Disk/Key 44 Chapter 3 Award BIOS BIOS Features Setup The table below describes the parameters found in this menu. Settings in boldface are the default and suggested settings. Parameter CPU Internal Cache Description Enabling this parameter activates the CPU internal cache. Disabling the parameter slows down the system. 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.

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. Normally, these areas are reserved for memory mapped I/O cards. Lets you configure the hard disk drive connected to the slave port of IDE channel 2. [. . . ] This system board supports both PC-100 (100MHz) and PC-133 (133 MHz) SDRAM. However, they cannot be used at the same time in a system. Please contact your dealer for qualified DIMM vendors. Do not use both PC-100 (100 MHz) and PC-133 (133 MHz) SDRAM together. Such a combination might cause your system to malfunction. Each of the DIMM sockets is independent from the others. [. . . ]
