BIOS Setup BIOS (Basic Input and Out System) includes a CMOS Setup utility which allows user to configure required settings or to activate certain system features. When the power is turned on, pushing the button during the Power-On Self test will take you to the CMOS Setup screen. If you still wish to enter Setup, restart the system by pressing the , and keys. You can also restart by turning the system Off and back On again.

CPU L1&L2 Cache This option allows you to enable or disable the cache function. Quick Power On Self Test When this option enabled, this field speeds up the Power On Self Test after the system is turned on. First/Second/Third Boot Device Floppy Select your boot device priority by Floppy. LS120 Select your boot device priority by LS120. Hard Disk Select your boot device priority by Hard Disk. CDROM Select your boot device priority by CDROM. ZIP Select your boot device priority by ZIP.
Typematic Rate (Chars/Sec) When enabled, the system registers repeated keystrokes speeds. Setting are from 6 to 30 characters per second. Typematic Delay When enabled, this option allows you to set the time interval for displaying the first and second characters. Security Option When setup, the system always boots up and prompt for the Supervisor Password only. When system, the system prompts for the User Password every time you boot up.
