58 PCM-4896 User Manual
Swap Floppy Drive
This field is effective only in systems with two floppy drives.
Selecting enabled assigns physical drive B to logical drive A, and
physical drive A to logical drive B.
Boot Up Floppy Seek
When Enabled, the BIOS tests (seeks) floppy drives to determine
whether they have 40 or 80 tracks. Only 360-KB floppy drives have
40 tracks; drives with 720 KB, 1.2 MB, and 1.44 MB capacity all
have 80 tracks. Because very few modern PCs have 40-track floppy
drives, we recommend that you set this field to Disabled to save
time.
Boot Up NumLock Status
Toggle between On or Off to control the state of the NumLock key
when the system boots. When toggled On, the numeric keypad
generates numbers instead of controlling cursor operations.
Gate A20 Option
Gate A20 refers to the way the system addresses memory above 1
MB (extended memory). When set to Fast, the system chipset
controls Gate A20. When set to Normal, a pin in the keyboard
controller controls Gate A20. Setting Gate A20 to Fast improves
system speed, particularly with OS/2 and Windows.
Security Option
If you have set a password, select whether the password is
required every time the System boots, or only when you enter
Setup.
