CPU Internal Cache/External Cache
These two categories, if enabled, can speed up memory access.
However, it depends on the CPU/chipset design.
Quick Power On Self Test
This category speeds up Power On Self Test (POST) after you
power up the computer. If it is set to Enabled, BIOS will shorten or
skip some check items during POST.
Boot Sequence
This category determines which drive to search first for the
operating system.
Swap Floppy Drive
This item allows you to swap the floppy drive assignments so that
drive A is treated as drive B and drive B is treated as drive A under
DOS. The default setting is Disabled.
Boot Up Floppy Seek
During POST, the BIOS will determine if the floppy disk drive
installed is 40 or 80 tracks. 360KB type is 40 tracks while 760KB,
1.2MB, and 1.44MB are all 80 tracks.
Boot Up NumLock Status
This allows you to determine the default state of the numeric
keypad on an IBM-compatible extended keyboard.
Boot Up System Speed
This allows you to determine the Boot Up Speed. The choices are
High/Low.
