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

Installation / Upgrade
--------------------------------------------------------------------------------
R E A D (!!!) THE INSTRUCTIONS IN THE Doc/INSTALL.xxxBSD FILES CAREFULLY !
==========================================================================
Again: PLEASE R E A D T H E M !!!!! (Thank You! ;-)
========================================
If you read them, you should have NO problems installing pcvt on your
system, if you don't read them, you'll probably run into problems ...
If you run into any difficulties, please read Doc/NotesAndHints !
NOTE 1:
-------
It is highly recommended in order to configure the driver into the system,
that you remove (and/or backup) your previous kernel compile directory and
do a fresh "config" with the new pcvt configuration. This has to be done
because the chain "config/make depend/make" obviously does not resolve ALL
dependencies!
NOTE 2:
-------
You MUST copy or link the Util/Makefile.inc.X for your flavour of xxx(x)BSD
to Util/Makefile.inc . This is because FreeBSD handles manual pages
in a differnet way than NetBSD. Also you have to edit Doc/Makefile
to make this changes for the pcvt(4) manpage.
NOTE 3:
-------
The driver now (from 2.10 on) DEPENDS on the BIOS video display setting
stored in the RTC CMOS Ram - verify your configuration setting!
NOTE 4:
-------
If you are using the pcvt termcap entry from Etc/Termcap, please reinstall
this into /usr/share/misc/termcap if you are upgrading, the entry had bugs
in release 3.10 and all earlier releases.
After doing that, you may need to generate a new termcap database for newer
FreeBSD (2.0 and up) and NetBSD (1.0 and up) Releases:
cd to /usr/share/misc and execute 'cap_mkdb termcap'.
NOTE 5:
-------
The default keyboard layout is documented in Doc/Keyboard.HP unless you
compiled with PCVT_VT220KEY which is described in Doc/Keyboard.VT. Please
note that PCVT_VT220KEYB is not much supported, because i don't use it.
NOTE 6:
-------
When upgrading from a previous version of the driver, you can remove now
the directory /usr/share/misc/vgafonts. It was moved in release 3.20 to
/usr/share/misc/pcvtfonts.
NOTE 7:
-------
In case you don't like pcvt's white on red kernel messages, have a look at
the end of pcvt_conf.h, this is the place to change them.
WYSIWYG - What You Share Is What You Get
--------------------------------------------------------------------------------
PLEASE, if you fix bugs, add features, hack this driver to work on your
hardware or simply don't get it up and running, get in contact with me!
Help us to avoid reinventing the wheel over and over again!
-----------------------------------------------------------
The code is far from being perfect, YOU are very welcome to enhance it !
Please mail bug reports/fixes, suggestions, enhancements & diffs to
hm@hcs.de or
hm@altona.hamburg.com
I will support this driver as my time permits it, feel free to contact me!
Have fun!
