UltraBay II Floppy drive

This is the 3.5" floppy drive for the UltraBay II slot.

Features

  • 3.5" 1.44Mb
  • Additional connector to allow attaching drive to proprietary external FDD connector port, allowing the ultrabay to be used for another device at the same time. Requires special cable (similar interface to a 760ED external floppy? The floppy end connector is the same as the Thinkpad end connector on a 760ED)

IBM Partnumbers

12J0425, cable 12J0432

Linux Support

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.
You can force the floppy driver to use both of them by adding the following line to /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.

If at boot there is a floppy drive attached to the external port, this is fd0 and the ultrabay is fd1. Otherwise (no floppies attached at boot/floppy in ultrabay at boot), then ultrabay is fd0 and external port is fd1. An ACPI-aware floppy driver would have the ablility to stop the devices swapping around, but such a thing doesn't exist.
