| 24 | * Ported to 386bsd Oct 17, 1992 |
| 25 | * Sandi Donno, Computer Science, University of Cape Town, South Africa |
| 26 | * Please send bug reports to sandi@cs.uct.ac.za |
| 27 | * |
| 28 | * Thanks are also due to Rick Macklem, rick@snowhite.cis.uoguelph.ca - |
| 29 | * although I was only partially successful in getting the alpha release |
| 30 | * of his "driver for the Logitech and ATI Inport Bus mice for use with |
| 31 | * 386bsd and the X386 port" to work with my Microsoft mouse, I nevertheless |
| 32 | * found his code to be an invaluable reference when porting this driver |
| 33 | * to 386bsd. |
| 34 | * |
| 35 | * Further modifications for latest 386BSD+patchkit and port to NetBSD, |
| 36 | * Andrew Herbert <andrew@werple.apana.org.au> - 8 June 1993 |
| 37 | * |
| 38 | * Cloned from the Microsoft Bus Mouse driver, also by Erik Forsberg, by |
| 39 | * Andrew Herbert - 12 June 1993 |
| 40 | * |
| 41 | * Modified for PS/2 mouse by Charles Hannum <mycroft@ai.mit.edu> |
| 42 | * - 13 June 1993 |
| 43 | * |
| 44 | * Modified for PS/2 AUX mouse by Shoji Yuen <yuen@nuie.nagoya-u.ac.jp> |
| 45 | * - 24 October 1993 |
| 46 | * |
| 47 | * Hardware access routines and probe logic rewritten by |
| 48 | * Kazutaka Yokota <yokota@zodiac.mech.utsunomiya-u.ac.jp> |
| 49 | * - 3, 14, 22 October 1996. |
| 50 | * - 12 November 1996. IOCTLs and rearranging `psmread', `psmioctl'... |
| 51 | * - 14, 30 November 1996. Uses `kbdio.c'. |
| 52 | * - 13 December 1996. Uses queuing version of `kbdio.c'. |
| 53 | * - January/February 1997. Tweaked probe logic for |
| 54 | * HiNote UltraII/Latitude/Armada laptops. |
| 55 | * - 30 July 1997. Added APM support. |
| 56 | * - 5 March 1997. Defined driver configuration flags (PSM_CONFIG_XXX). |
| 57 | * Improved sync check logic. |
| 58 | * Vendor specific support routines. |
