MAINBOARD BIOS SETUP
BIOS, Driver & Utility Guide
12
Quick Power on Self Test - Speeds up Power On Self Test (POST) after the
computer is powered on. When set to Enabled , the BIOS will shorten or skip some
checks during POST.
Boot Sequence - When your system is powered on, the BIOS performs a variety of
operations, then attempts to boot an Operating System from either a hard drive
(IDE or SCSI), floppy drive, CD-ROM or LS-120/ZIP. This setting determines the
sequence that the BIOS will follow when searching devices for a bootable disk.
Most users find the C, A, SCSI setting to be most beneficial, since it takes the least
amount of time to boot the system. If however, you want the ability to boot from a
Floppy or CD-ROM drive, you would need to choose either the
A, C, SCSI or
CDROM, C, A setting. For instance, if your boot sequence was set to C, A, SCSI
and for some reason you wanted to boot to your Floppy A: Drive, it would not be
possible, since the BIOS would always boot from the C: drive first. In this case,
this setting would need to be changed to
A, C, SCSI so that the system would first
check the floppy drive for a bootable disk. This would slow bootup speed, however,
since the floppy would be checked on every boot.
Swap Floppy Drive - The hardware connections determine which floppy is
configured as drive A: and drive B: “Swapping” the floppy drives can be useful if
your system has two floppy drives, and you want the ability to boot from both. For
example: Since a PC cannot boot from the B: Floppy, you would need to “Swap”
floppy drives A: and B: in order to set the second floppy drive to drive A:, thereby
making it bootable.
Boot Up Floppy Seek - When enabled, BIOS will attempt to move the head of the
floppy disk drive forth and back once during POST to see if the drive is working
properly.
Boot Up NumLock Status - When On , the NumLock key will be automatically
enabled when the system boots.
Gate A20 Option - This entry allows you to select how the gate A20 is handled.
The gate A20 is a device used to address memory above 1 Mbytes. Initially, the
gate A20 was handled via a pin on the keyboard (Normal). Today, while keyboards
still provide this support, it is more common, and much faster, for the system
chipset (Fast; default) to provide support for gate A20.
