Description sdn 2002-02-26 02:20:01 UTC 
I find the following inaccuracies at 
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/x-config.html

The docs say:

    # XFree86 -configure

I get:

% XFree86 -configure
XFree86 Version 4.1.0 / X Window System
(protocol Version 11, revision 0, vendor release 6510)
Release Date: 2 June 2001
        If the server is older than 6-12 months, or if your card is
        newer than the above date, look for a newer version before
        reporting problems.  (See http://www.XFree86.Org/FAQ)
Build Operating System: FreeBSD 4.5-RELEASE i386 [ELF] 
Module Loader present
(==) Log file: "/var/log/XFree86.0.log", Time: Mon Feb 25 16:32:31 2002
(--) Using syscons driver with X support (version 2.0)
(--) using VT number 9


Fatal server error:
xf86EnableIO: Failed to open /dev/io for extended I/O


When reporting a problem related to a server crash, please send
the full server output, not just the last messages.
This can be found in the log file "/var/log/XFree86.0.log".
Please report problems to xfree86@xfree86.org.


It doesn't seem to work.
Most i810 advice that I find on the internet is also in some
way inaccurate.

Is there any accurate information that can advise me on how
to get the i810 video chipset working with X?

Fix: 

Somewhere, somehow, there must be some accurate information
on the i810 video chip and X.
How-To-Repeat: Just run the command on an i810 system

State Changed
From-To: open->closed

The documentation is accurate.  I've helped several people set up 
their XFree86 servers on various systems using the i810. 

Notice the instructions say to run (as super user), 
# XFree86 -configure 

Run this as root, and follow the rest of the instructions.

I'm having the same problem, setting up XFree86 on my machine.  I'm running as root, and type:

XFree86 -configure

getting the error:

xf86EnableIO: Failed to open /dev/io for extended I/O

please help!!!

I believe I had set my kernel secure levels above 0.
Reduce your securelevel to 0 or -1 and try again.
