FAQ list:
=========

A FAQ list may be found in the fdutils package (see below), and also
at <https://fdutils.linux.lu/faq.html>.


LILO configuration options (Thinkpad users, read this)
======================================================

The floppy driver is configured using the 'floppy=' option in
lilo. This option can be typed at the boot prompt, or entered in the
lilo configuration file.

Example: If your kernel is called linux-2.6.9, type the following line
at the lilo boot prompt (if you have a thinkpad)::

 linux-2.6.9 floppy=thinkpad

You may also enter the following line in /etc/lilo.conf, in the description
of linux-2.6.9::

 append = "floppy=thinkpad"

Several floppy related options may be given, example::

 linux-2.6.9 floppy=daring floppy=two_fdc
 append = "floppy=daring floppy=two_fdc"

If you give options both in the lilo config file and on the boot
prompt, the option strings of both places are concatenated, the boot
prompt options coming last. That's why there are also options to
restore the default behavior.


Module configuration options
============================

If you use the floppy driver as a module, use the following syntax::

	modprobe floppy floppy="<options>"

Example::

	modprobe floppy floppy="omnibook messages"

If you need certain options enabled every time you load the floppy driver,
you can put::

	options floppy floppy="omnibook messages"

in a configuration file in /etc/modprobe.d/.


The floppy driver related options are:

 floppy=asus_pci
	Sets the bit mask to allow only units 0 and 1. (default)

 floppy=daring
	Tells the floppy driver that you have a well behaved floppy controller.
	This allows more efficient and smoother operation, but may fail on
	certain controllers. This may speed up certain operations.

 floppy=0,daring
	Tells the floppy driver that your floppy controller should be used
