[. . . ] If you are running such a program, we recommend that you first disable this field. CPU Internal Cache and External Cache These fields speed up the memory access. The default is Enabled, which provides better performance by enabling cache. 71 3 BIOS Setup Quick Power On Self Test This field speeds up Power On Self Test (POST) whenever the system is powered on. The BIOS will shorten or skip some check items during POST. To attain the shor test POST time, select "Enabled". First Boot Device, Second Boot Device, Third Boot Device and Boot Other Device Select the drive to boot first, second and third in the "First Boot Device" "Second Boot Device" and "Third Boot Device" fields respectively. The BIOS will boot the operating system according to the sequence of the drive selected. Set "Boot Other Device" to Enabled if you wish to boot from another device. Swap Floppy Drive When this field is enabled and the system is booting from the floppy drive, the system will boot from drive B instead of drive A. When this field is disabled and the system is booting from the floppy drive, the system will boot from drive A. You must have two floppy drives to use this function. Boot Up Floppy Seek When enabled, the BIOS will check whether the floppy disk drive installed is 40 or 80 tracks. Note that the BIOS cannot distinguish between 720K, 1. 2M, 1. 44M and 2. 88M drive types as they are all 80 tracks. When disabled, the BIOS will not search for the type of floppy disk drive by track number. 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. 72 BIOS Setup Gate A20 Option This field allows you to select how gate A20 is handled. Gate A20 is a device used to address memory above 1 Mbyte. Initially, gate A20 was handled via the keyboard controller. Today, while keyboards still provide this support, it is more common, and much faster, for the system chipset to provide support for gate A20. A20 refers to the first 64KB of extended memory. [. . . ] If your hard drive takes an excessively long period of time to format, it is likely a cable connection problem. However, if your hard drive has a large capacity, it will take a longer time to format. Parallel Port The parallel printer doesn't respond when you try to print. Make sure that your printer is turned on and that the printer is on-line. Make sure your software is configured for the right type of printer attached. [. . . ]
