BOOT Other Device function. The system will automatically boot
the other device.

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.
The choices: Enabled, Disabled.

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 you to choose "Disabled" to save time.
The choices: Enabled, Disabled.
