29 The major contributors to pcvt are Brian and Joerg, pcvt would not be what it
30 is without the help, the support and the code from Joerg:
32 Brian Dunford-Shore (brian@athe.wustl.edu)
34 wrote parts of the EGA/VGA hardware handling and
35 some of the more ugly aspects of the VT220.
37 Joerg Wunsch (joerg_wunsch@uriah.heep.sax.de)
39 added ALL support for XFree86, the screensaver sub-
40 system and support for FreeBSD (and much more ...).

194 Installation / Upgrade
195 --------------------------------------------------------------------------------
197 R E A D (!!!) THE INSTRUCTIONS IN THE Doc/INSTALL.xxxBSD FILES CAREFULLY !
198 ==========================================================================
200 Again: PLEASE R E A D T H E M !!!!! (Thank You! ;-)
201 ========================================
203 If you read them, you should have NO problems installing pcvt on your
204 system, if you don't read them, you'll probably run into problems ...
206 If you run into any difficulties, please read Doc/NotesAndHints !
210 It is highly recommended in order to configure the driver into the system,
211 that you remove (and/or backup) your previous kernel compile directory and
212 do a fresh "config" with the new pcvt configuration. This has to be done
213 because the chain "config/make depend/make" obviously does not resolve ALL
218 You MUST copy or link the Util/Makefile.inc.X for your flavour of xxx(x)BSD
219 to Util/Makefile.inc . This is because FreeBSD handles manual pages
220 in a differnet way than NetBSD. Also you have to edit Doc/Makefile
221 to make this changes for the pcvt(4) manpage.
225 The driver now (from 2.10 on) DEPENDS on the BIOS video display setting
226 stored in the RTC CMOS Ram - verify your configuration setting!
230 If you are using the pcvt termcap entry from Etc/Termcap, please reinstall
231 this into /usr/share/misc/termcap if you are upgrading, the entry had bugs
232 in release 3.10 and all earlier releases.
234 After doing that, you may need to generate a new termcap database for newer
235 FreeBSD (2.0 and up) and NetBSD (1.0 and up) Releases:
236 cd to /usr/share/misc and execute 'cap_mkdb termcap'.
240 The default keyboard layout is documented in Doc/Keyboard.HP unless you
241 compiled with PCVT_VT220KEY which is described in Doc/Keyboard.VT. Please
242 note that PCVT_VT220KEYB is not much supported, because i don't use it.
246 When upgrading from a previous version of the driver, you can remove now
247 the directory /usr/share/misc/vgafonts. It was moved in release 3.20 to
248 /usr/share/misc/pcvtfonts.
252 In case you don't like pcvt's white on red kernel messages, have a look at
253 the end of pcvt_conf.h, this is the place to change them.
256 WYSIWYG - What You Share Is What You Get
257 --------------------------------------------------------------------------------
259 PLEASE, if you fix bugs, add features, hack this driver to work on your
260 hardware or simply don't get it up and running, get in contact with me!
262 Help us to avoid reinventing the wheel over and over again!
263 -----------------------------------------------------------
265 The code is far from being perfect, YOU are very welcome to enhance it !
266 Please mail bug reports/fixes, suggestions, enhancements & diffs to
269 hm@altona.hamburg.com
271 I will support this driver as my time permits it, feel free to contact me!
