-In case you have two floppy drives, or want to attach the floppy drive externally after boot, the floppy drivers hardware autodetection cannot be relied upon.<br />
+In the case that you have two FDDs, or want to attach the FDD externally after the booting process; be aware that the floppy drivers' hardware auto-detection cannot be relied upon. However, you can force the floppy driver to use both of them by adding the following line to {{path|/etc/modprobe.conf}}:
   options floppy floppy=1,4,cmos
-This gives you support for either external floppy or ultrabay floppy or both if you plug them in after boot time.
+This will give you support for either external FDD, or UltraBay II FDD, or both if you plug them in after the booting process.
-=== Supported with ===
+If there is a FDD attached to the external port during the boot process, it will be identified as {{path|/dev/fd0}} and the FDD in the UltraBay II will be identified as {{path|/dev/fd1}}. Otherwise (assuming no FDDs are externally attached during boot or FDD in UltraBay II during boot), the UltraBay II FDD would be assigned as {{path|/dev/fd0}} and external port would be assigned as {{path|/dev/fd1}}. An ACPI-aware floppy driver would have the ability to stop the devices from swapping around, but such a thing doesn't exist yet.
