Setting to On will turn on the Num Lock key when the system is powered on. Setting to Off will allow users to use the arrow keys on the numeric keypad. When the default value Fast is selected, the Gate A20 is controlled by Port92 or chipset specific method resulting in faster system performance. When Normal is selected, A20 is controlled by a keyboard controller or chipset hardware. Typematic Rate Setting This setting is used to enable or disable the typematic rate setting including Typematic Rate & Typematic Delay. Typematic Rate (Chars/Sec) After Typematic Rate Setting is enabled, this item allows you to set the rate (characters/second) at which the keys are accelerated. Typematic Delay (Msec) This item allows you to select the delay between when the key was first pressed and when the acceleration begins. Settings: 250, 500, 750 and 1000. Typematic Delay (Msec) This item allows you to select the delay between when the key was first pressed and when the acceleration begins.

MPS Table Version This field allows you to select which MPS (Multi-Processor Specification) version to be used for the operating system. You need to select the MPS version supported by your operating system. [. . . ] LED (Light Emitting Diode) A semiconductor device that converts electrical energy into light. Since it lights up (usually red) when electricity is passed through it, it is usually used for the activity lights on computer's component, such as disk drivers. LPT (Line Printer Terminal) Logical device name for a line printer; a name reserved by the MS-DOS for up to three parallel printer ports: LPT1, LPT2, and LPT3. Overclocking Overclocking is resetting your computer so that the microprocessor runs faster than the manufacturer-specified speed (for example, setting an Intel 166 MHz (megahertz) microprocessor to run at 200 Mhz).
