[. . . ] The default is enabled. Shadow Memory Regions Allows you to choose which specific memory regions will be shadowed. The default is for all specific regions disabled. 39 Chapter 3 - Using SETUP Boot Sequence Menu The boot sequence sub-menu allows you to speed up boot time by disabling certain standard computer boot procedures. Keyboard Auto-repeat Rate Defines the rate the keyboard repeats when a key is pressed and held. The number displayed represents the number of repetitions per second the keyboard will generate. The default is 30 times per second. Keyboard Auto-repeat Delay Defines time delay between the time a key is depressed and the time the key begins to repeat. The default is 1/2 second. Key Click When selected, provides an audible feedback whenever a key is pressed. Numlock This option defines how the Num Lock key should work on power up. The Num Lock key is used to determine whether the cursor keys or the numeric keys are active on the keypad. Normally, the BIOS sets the Num Lock (numeric keys active) if the system detects a compatible keyboard on power up. Auto On Off Sets the Num Lock (numeric keys active) if the system detects a compatible keyboard on power up (default) Selects the numeric keys regardless of the keyboard Selects the cursor movement keys regardless of the keyboard Summary screen During normal boot, the system BIOS displays a summary screen of your computer configuration at boot. Disabling the system summary screen at boot skips this display. 40 Chapter 3 - Using SETUP Floppy Check When enabled the system checks that each floppy drive configured in CMOS memory is operational. Disabling floppy check skips this step, speeding up boot time. Floppy Swap For systems that boot using DOS, allows you to swap the drive designation for floppy drives A: and B:. Disabled uses the drives as they are installed. Note: Not implemented on all systems. Boot Sequence During boot the computer looks for an operating system stored on the floppy boot drive or logical drive C on an installed hard drive. Disk drive boot sequence determines which drive is checked first. The default is [A: then C:], meaning the system will check floppy drive A first, then if no operating system is present, it will look on drive C. If you normally boot from the hard disk C, setting this option to [C: then A:] or [C: only] will speed your boot time. SETUP prompt When enabled, the system displays the message "Press F2 to enter SETUP" on boot. When disabled this step is skipped on boot. POST errors When enabled, the system pauses whenever it finds an error during bootup and displays the message "Press F1 to continue or F2 to enter SETUP". When disabled the system ignores POST errors during boot. The default is enabled. 41 Chapter 3 - Using SETUP Advanced Menu Warning! Setting these items incorrectly could disable your system. Never needlessly change from the defaults. The Advanced Menu offers the following options: Large Disk DOS Compatibility Enables or Disables Logical Block Addressing, enabling you to use very large IDE hard drives. Note: Not implemented on all systems. Integrated Peripherals This menu allows you to set the addresses, interrupts and DMA channels for your serial, parallel, and audio ports. Com Port A: When either Com Port 1 or Com Port 2 is set to Auto, the system will automatically set the interrupts for both ports. Otherwise this option allows you to set the interrupt and I/O address of the COM1 serial port. Com Port B: When either Com Port 1 or Com Port 2 is set to Auto, the system will automatically set the interrupts for both ports. Otherwise this option allows you to set the interrupt and I/O address of the COM2 serial port. 42 Chapter 3 - Using SETUP Parallel Port Sets the parallel port designation. The default setting of Auto allows the system to automatically assign the first available parallel port designation to the on-board parallel port (usually LPT1). Otherwise allows you to specify the parallel port address. [. . . ] Operating System - A collection of programs that allow a computer to control its operations. The Operating System determines how programs run on the computer and supervises all input and output for example, MS-DOS. Parallel - The type of interface which transmits data in groups of bits. Peripheral - A device (such as, a printer or a modem) connected to a computer that depends on the computer for its operation. [. . . ]
