floppy drive assignments so that Drive A becomes Drive B, and Drive B becomes Drive A. By default, this field is
set to Disabled.

Boot Up Floppy Seek

When enabled, the BIOS will seek whether or not the floppy drive installed has 40 or 80 tracks. 360K type has
40 tracks while 760K, 1.2M and 1.44M all have 80 tracks. By default, this field is set to Enabled.

with NumLock On.

always boots up and prompts for the Supervisor Password only when the Setup utility is called up.
