Caution To avoid damage to the system: Use the correct AC input voltage range. [. . . ] Note that there will not be any warning message if the drive installed is 360KB. Boot Up NumLock Status This allows you to determine the default state of the numeric keypad. By default, the system boots up with NumLock on wherein the function of the numeric keypad is the number keys. When set to Off, the function of the numeric keypad is the arrow keys. Gate A20 Option This entry allows you to select how gate A20 is handled. Today, while keyboards still provide this support, it is more common, and much faster, for the system chipset to provide support for gate A20. Security Option This field determines when the system will prompt for the password - everytime the system boots or only when you enter the BIOS setup. System The system will not boot and access to Setup will be denied unless the correct password is entered at the prompt. Setup The system will boot, but access to Setup will be denied unless the correct password is entered at the prompt. 52 Award BIOS Setup Utility OS Select for DRAM > 64MB This field allows you to access the memory that is over 64MB in OS/2. Video BIOS Shadow Determines whether video BIOS will be copied to RAM. C8000-CBFFF Shadow to DC000-DFFFF Shadow These fields determine whether option ROMs will be copied to RAM. This allows PCI and ISA buses to be used more efficiently and prevents degradation of performance on the PCI bus when ISA accesses are made. PCI#2 Access #1 Retry Set this field to Enabled if you want to rotate the priority of the PCI masters. AGP Master 1 WS Write Set this field to Enabled to add one clock tick to AGP write operations. Enabled 56 Award BIOS Setup Utility AGP Master 1 WS Read Set this field to Enabled to add one clock tick to AGP read operations. Memory Parity/ECC Check If you are using x72 (72-bit) PC SDRAM DIMMs, which are DIMMs that support the ECC (Error Checking and Correction) function, set this field to Enabled. ! 57 !

In the actual CMOS setup, you have to use the scroll bar to view the fields. Your version may not be identical to this one. OnChip IDE Channel0 and OnChip IDE Channel1 These fields allow you to enable or disable the primary and secondary IDE controller. IDE Prefetch Mode This allows data and addresses to be stored in the internal buffer of the chip, thus reducing access time. Enable this field to achieve better performance. 58 Award BIOS Setup Utility IDE Primary Master/Slave PIO and IDE Secondary Master/Slave PIO PIO means Programmed Input/Output. Rather than have the BIOS issue a series of commands to effect a transfer to or from the disk drive, PIO allows the BIOS to tell the controller what it wants and then let the controller and the CPU perform the complete task by themselves. Your system supports five modes, 0 (default) to 4, which primarily differ in timing. [. . . ] If the monitor is close to another monitor, the adjacent monitor may need to be turned off. Fluorescent lights adjacent to the monitor may also cause screen wavering. + Power Supply When the computer is turned on, nothing happens. Check that one end of the AC power cord is plugged into a live outlet and the other end properly plugged into the back of the system. Make sure that the voltage selection switch on the back panel is set for the correct type of voltage you are using. [. . . ]
