Swap Floppy Drive
Common Options : Enabled, Disabled
Quick Review
This BIOS feature is used to logically swap the mapping of drives A: and B:. Therefore, it is only useful if you have two floppy drives.
Normally, the sequence by which you connect the floppy drives to the cable determines which is drive A: and which is drive B:. If you attach the floppy drives the wrong way and obtain a drive mapping that is not to your satisfaction, the usual way of correcting this is to physically swap the floppy cable connectors.
This feature allows you to swap the logical arrangement of the floppy drives without the need to open up the case and physically swap the connectors.
When this BIOS feature is enabled, the floppy drive that originally was mapped to drive A: will be remapped to drive B: and vice versa for the drive that was originally set as drive B:.
When this BIOS feature is disabled, the floppy drive mapping will remain as that set by the drive connector arrangement.
Although this appears to be nothing more than a feature of convenience, it can be quite important if you are using two floppy drives of different form factors (3.5" and 5.25") and you need to boot from the second drive. Because the BIOS can only boot from drive A:, you will have to physically swap the drive connections or use BIOS this feature to do it logically.
If your floppy drive mapping is correct or if you only have a single floppy drive, there is no need to enable this feature. Leave it at the default setting of disabled.
