--------------------------------------------------------------------------------
386BSD 0.1 + patchkit 0.2.4 pcvt beta 16 tested
NetBSD 0.9 pcvt beta 14 tested
NetBSD-current pcvt beta 16 tested
-current as of February 5th 1994
(got a fix for Feb 12, see pcvt_drv.c,
search for NETBSD_CURRENT_12_02_94)
FreeBSD 1.0.2 pcvt beta 16 tested
FreeBSD-current pcvt beta 14 was tested against FreeBSD
-current as of late January 1994
(pcvt beta 16 was the last beta before the 3.00 release)
Installation / Upgrade
--------------------------------------------------------------------------------
R E A D (!!!) THE INSTRUCTIONS IN THE Doc/INSTALLATION.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 ....
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
different than NetBSD and 386BSD 0.1. 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!
WYSIWYG - What You Share Is What You Get
--------------------------------------------------------------------------------
While beta-testing this driver, i learned that there are no two video boards
which are compatible. Same applies to the keyboard interface on motherboards.
We got this driver to compile and run on the majority of the tested machines,
but not on all. The configurations failing to run this driver were not very
exotic, but because i don't own all sorts of hardware, in many cases i could
only guess ....
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@hcshh.hcs.de
I will support this driver as my time permits it, feel free to contact me!
Have Fun !
Hellmuth
