Remove mouse drivers no longer needed, because these mice are 

now handled by the input subsystem.

The module will be called busmouse.o. If you want to compile it as a
module, say M here and read <file:Documentation/modules.txt>.
CONFIG_MOUSE
This is for machines with a mouse which is neither a serial nor a
bus mouse. Examples are PS/2 mice (such as the track balls on some
laptops) and some digitizer pads. Most people have a regular serial
MouseSystem or Microsoft mouse (made by Logitech) that plugs into a
COM port (rectangular with 9 or 25 pins). These people say N here.
If you have something else, read the Busmouse-HOWTO, available from
<http://www.linuxdoc.org/docs.html#howto>. This HOWTO contains
information about all non-serial mice, not just bus mice.
If you have a laptop, you either have to check the documentation or
experiment a bit to find out whether the trackball is a serial mouse
or not; it's best to say Y here for you.
Note that the answer to this question won't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about non-serial mice. If unsure, say Y.
CONFIG_LOGIBUSMOUSE
Logitech mouse connected to a proprietary interface card. It's
generally a round connector with 9 pins. Note that the newer mice
made by Logitech don't use the Logitech protocol anymore; for those,
you don't need this option. You want to read the Busmouse-HOWTO,
available from <http://www.linuxdoc.org/docs.html#howto>.
If you want to compile this as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read <file:Documentation/modules.txt>. The module
will be called busmouse.o. If you are unsure, say N and read the
HOWTO nevertheless: it will tell you what you have.
CONFIG_PSMOUSE
The PS/2 mouse connects to a special mouse port that looks much like
the keyboard port (small circular connector with 6 pins). This way,

<ftp://gnu.systemy.it/pub/gpm/>) solves this problem, or you can get
the "mconv2" utility from <ftp://ibiblio.org/pub/Linux/system/mouse/>.
CONFIG_82C710_MOUSE
This is a certain kind of PS/2 mouse used on the TI Travelmate. If
you are unsure, try first to say N here and come back if the mouse
doesn't work. Read the Busmouse-HOWTO, available from
<http://www.linuxdoc.org/docs.html#howto>.
CONFIG_PC110_PAD
This drives the digitizer pad on the IBM PC110 palmtop. It can turn
the digitizer pad into a PS/2 mouse emulation with tap gestures or
into an absolute pad.
If you want to compile this as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read <file:Documentation/modules.txt>. The module
will be called pc110pad.o.
CONFIG_MS_BUSMOUSE
These animals (also called Inport mice) are connected to an
expansion board using a round connector with 9 pins. If this is what
you have, say Y and read the Busmouse-HOWTO, available from
<http://www.linuxdoc.org/docs.html#howto>.
If you are unsure, say N and read the HOWTO nevertheless: it will
tell you what you have. Also be aware that several vendors talk
about 'Microsoft busmouse' and actually mean PS/2 busmouse -- so
count the pins on the connector.
If you want to compile this as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read <file:Documentation/modules.txt>. The module
will be called msbusmouse.o.
CONFIG_ADBMOUSE
Say Y here if you have this type of bus mouse (4 pin connector) as
is common on Macintoshes. You may want to read the Busmouse-HOWTO,
available from <http://www.linuxdoc.org/docs.html#howto>.
If you want to compile this as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read <file:Documentation/modules.txt>. The module
will be called adbmouse.o.
CONFIG_ATIXL_BUSMOUSE
This is a rare type of busmouse that is connected to the back of an
ATI video card. Say Y if you have one of those. Note however that
most mice by ATI are actually Microsoft busmice; you should say Y to
"Microsoft busmouse support" above if you have one of those. Read
the Busmouse-HOWTO, available from
<http://www.linuxdoc.org/docs.html#howto>.
If you want to compile this as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read <file:Documentation/modules.txt>. The module
will be called atixlmouse.o.
If you are unsure, say N and read the HOWTO nevertheless: it will
tell you what you have.

* Modified by Johan Myreen to make room for other mice (9AUG92)
* removed assignment chr_fops[10] = &mouse_fops; see mouse.c

/*
* Logitech Bus Mouse Driver for Linux
* by James Banks
*
* Mods by Matthew Dillon
* calls verify_area()
* tracks better when X is busy or paging
*
* Heavily modified by David Giller
* changed from queue- to counter- driven
* hacked out a (probably incorrect) mouse_select
*
* Modified again by Nathan Laredo to interface with
* 0.96c-pl1 IRQ handling changes (13JUL92)
* didn't bother touching select code.
*
* Modified the select() code blindly to conform to the VFS
* requirements. 92.07.14 - Linus. Somebody should test it out.
*
* Modified by Johan Myreen to make room for other mice (9AUG92)
* removed assignment chr_fops[10] = &mouse_fops; see mouse.c
* renamed mouse_fops => bus_mouse_fops, made bus_mouse_fops public.
* renamed this file mouse.c => busmouse.c
*
* Minor addition by Cliff Matthews
* added fasync support
*
* Modularised 6-Sep-95 Philip Blundell <pjb27@cam.ac.uk>
*
* Replaced dumb busy loop with udelay() 16 Nov 95
* Nathan Laredo <laredo@gnu.ai.mit.edu>
*
* Track I/O ports with request_region(). 12 Dec 95 Philip Blundell
*
* Converted to use new generic busmouse code. 5 Apr 1998
* Russell King <rmk@arm.uk.linux.org>

*
* Microsoft Bus Mouse support folded into 0.97pl4 code
* by Peter Cervasio (pete%q106fm.uucp@wupost.wustl.edu) (08SEP92)
* Changes: Logitech and Microsoft support in the same kernel.
* Defined new constants in busmouse.h for MS mice.
* Added int mse_busmouse_type to distinguish busmouse types
* Added a couple of new functions to handle differences in using
* MS vs. Logitech (where the int variable wasn't appropriate).
*
* Modified by Peter Cervasio (address above) (26SEP92)
* Changes: Included code to (properly?) detect when a Microsoft mouse is
* really attached to the machine. Don't know what this does to
* Logitech bus mice, but all it does is read ports.
*
* Modified by Christoph Niemann (niemann@rubdv15.etdv.ruhr-uni-bochum.de)

* Some changes to reduce code-size.

* The pad provides triples of data. The first byte has
* 0x80=bit 8 X, 0x01=bit 7 X, 0x08=bit 8 Y, 0x01=still down
* The second byte is bits 0-6 X
* The third is bits 0-6 Y
*
* This is read internally and used to synthesize a stream of
* triples in the form expected from a PS/2 device. Specialist
* applications can choose to obtain the pad data in other formats
* including a debugging mode.
*
* It would be good to add a joystick driver mode to this pad so
* that doom and other game playing are better. One possible approach
* would be to deactive the mouse mode while the joystick port is opened.
