Chapter 3 Introducing BIOS The BIOS is a program located on a Flash Memory on the motherboard. This program is a bridge between motherboard and operating system. When you start the computer, the BIOS program will gain control. The BIOS first operates an auto-diagnostic test called POST (power on self test) for all the necessary hardware, it detects the entire hardware device and configures the parameters of the hardware synchronization.
If the message disappears before your respond and you still wish to enter Setup, restart the system to try again by turning it OFF then ON or pressing the “RESET” button on the system case. You may also restart by simultaneously pressing , and keys.

Virus Warning The selection Allow you to choose the VIRUS Warning feature for IDE Hard Disk boot sector protection. If this function is enabled and someone attempt to write data into this area, BIOS will show a warning message on screen and alarm beep. Disabled (default) No warning message to appear when anything attempts to access the boot sector or hard disk partition table.
On (default) Keypad is numeric keys. Keypad is arrow keys. Off Gate A20 Option The A20 signal is controlled by keyboard controller or chipset hardware. Normal The A20 signal is controlled by port 92 or chipset specific method. Fast (default) Typematic Rate Setting Keystrokes repeat at a rate determined by the keyboard controller. When enabled, the typematic rate and typematic delay can be selected. The settings are: Enabled/Disabled.

This item allows you setting the FAN works in full speed when the temperature over the value which out set. If the temperature below the value but over the Idle Temperature, the FAN will works over 60% of full speed, and the higher temperature will gain higher FAN speed, after over the temperature which this item setting, the FAN works in full speed. CPU Idle Temp This item allows you setting the FAN works in 60% of full speed, when the temperature lower than the temperature which you setting.
3-7 Power Management Setup The Power Management Setup allows you to configure your system to most effectively save energy saving while operating in a manner consistent with your own style of computer use.
DPMS (default) Initial display power management signaling. This option only writes blanks to the video buffer. Blank Screen V/H SYNC+Blank This selection will cause the system to turn off the vertical and horizontal synchronization ports and write blanks to the video buffer. .MODEM Use IRQ If you want an incoming call on a modem to automatically resume the system from a power-saving mode, use this item to specify the interrupt request line (IRQ) that is used by the modem.
