David,
Got the document I saved.
Here it is.
The essence is to reserve 1M of the system memory for the i810 frame buffer.

IntelR 810 Chipset Family
Linux* Installation Guide
This document details how to get Linux* up and running on your system that is using
either an IntelR 810 or an IntelR 810E chipset. This information was written using Red
Hat* 6.0 as a reference platform, some details may not be valid on other distributions
or versions.

Kernel version 2.2.X
Glibc 2.1
gcc
Installing a new system:
If you are installing a Linux* distribution on a new system there are a few things you
should know to help with the install. Distributions that are using XFree86 3.3.5 or
earlier do not have built-in support for the IntelR 810 Chipset family You will have
to install the 'vga16' X server, then after your system has been loaded you can get
and install the accelerated X server. Also, there may be an issue with the
distribution not recognizing all of the memory in your system. This should not cause a
problem with the installation and can be fixed after the install is done as is
detailed below. Be sure, when doing your install, that you include the gcc compiler.
It is needed to compile the agpgart module. All other aspects of the install should
proceed as expected.
Kernel setup:
Check your Memory.
Linux* kernel 2.2.X has a problem recognizing all the memory on some IntelR 810 and
IntelR 810E chipsetbased systems. This will make the system seem very slow, or just
not as fast as it could be. To check your system, run this command at a command
prompt.
cat /proc/meminfo
Look for a line that says:
MemTotal: XXXXX kb
If this number is not close to the amount of RAM in your system, you will have to tell
the kernel how much RAM you have. Note that this should be about 1-2 MB less than your
actual system memory amount of installed RAM . This is because the graphics chip uses
system RAM for its 1MB frame-buffer.
Specify an amount of RAM.
For the kernel to know how much RAM you have available for use you will need to supply
a kernel boot parameter to LILO either at the boot prompt or in the configuration
file. At the LILO prompt enter the name of the kernel you want (Usually 'linux' unless
you changed it) followed by mem=##M. The ## is the amount of memory you have in
megabytes. REMEMBER to subtract 1 MB for the part taken by the graphics acelerator
otherwise your kernel may experience diffuiculties during boot-up. If you still
experience problems after making this change , subtract another 1MB,as this could be
taken by vendor specific BIOS needs.
LILO: linux mem=63M
After verifying that this works you should add it to LILO permanently by editing the
lilo.conf file. This file is usually located at /etc/lilo.conf. After the line
'label=linux' (Or whatever you called your kernel) add a line like:
append="mem=63M"
Change the 63MB above to be the amount of ram you have - 1M. Save this file and as
root reinstall LILO by running:
/sbin/lilo
This should reinstall your boot loader and you will automatically tell the kernel how
much RAM you have on your next reboot. If you are currently running with the correct
amount of RAM you do not need to reboot. If at a future date, you change the amount of
RAM in your system you will need to repeat the above procedure.
If you are loading your kernel without using LILO consult the loader's documentation
for how to supply 'kernel parameters' when booting the kernel. Add the 'mem=##M'
parameter in that fashion.
X Server Installation:
Find your XFree86 version.
To determine what version of X your distribution has installed you can run:
X -version
Install XFree86 3.3.5
If you do not have it already, you will need to download and install XFree86 version
3.3.5. If your distribution came with a version of XFree86 earlier than 3.3.5 your
should check to see if an upgrade is available from your distribution's web site. If
your distribution does not have an upgrade available you can download it directly from
the XFree86.org web site.
When installing XFree86 you should use the vga16 server. The maximum resolution with
this "compatibility" server will be 640x480x16. After you have successfully installed
the vga16 server you can upgrade your install with the XFCom-I810 X server which will
support high resolution modes.
Download XFCom-I810 and agpgart.
Download the XFree86 3.3.5 accelerated X server for the IntelR 810 chipset family
(XFCom-i810) from support.intel.com. This is available in either RPM or tar formats,
choose the one your distribution supports.
You will also need to download the agpgart.o source. This is available in either a
source RPM or a tar format, choose the one you distribution supports.
Install XFCom-I810.
You will need to be root to do this.
RPM:
rpm -Uvh XFCom-i810-glibc2.1-1.0.0-rh60.i386.rpm
TAR:
tar -zxpvf XFCom-i810-glibc2.1-1.0.0.tar.gz
cd XFCom-i810-glibc2.1-1.0.0
./INSTALL
Compile and install the kernel module
The kernel module must be compiled before it can be installed. This module will need
to be recompiled and reinstalled if you upgrade your kernel at a later date, so keep
the source in a safe place.
RPM:
rpm --rebuild I810Gtt-0.1-4.src.rpm
# Look for the output near the bottom that says where the rpm
# was built. Use that rpm name in the next command if you are
# not on a RedHat system.
rpm -Uvh /usr/src/redhat/RPMS/i386/i810Gtt-0.1-4.i386.rpm
TAR:
mkdir temp_i810
cd temp_i810
tar -zxpvf /path to tar/I810Gtt-0.1-4.src.tar.gz
make
make install
# You may remove the temp_i810 and its contents if you wish.
Edit the XF86Config file.
Setup your XF86Config file. Use your favorite text editor to edit the file
/etc/X11/XF86Config. You will need to be root to do this. Add the following device
section to your XF86Config file. There should be other similar device sections already
in the file. You can add this to the file without changing other device sections.
Section "Device"
Identifier "i810"
EndSection
Add this screen section, you should remove any other "svga" screen sections that may
be in this file. Do not remove the vga16 screen section, as it would be useful if you
should ever need to fall back to vga mode. You must edit the Monitor line to reflect
the Monitor you have. You can get this from another "Screen" section in this file, or
from the "Monitor" section of the XF86Config file. Be careful not to specify modes
that your Monitor cannot support, you could damage the Monitor.
Section "Screen"
Driver "svga"
Device "i810"
Monitor ""
Subsection "Display"
Depth 8
Modes "640x480" "800x600" "1024x768" "1152x864" "1280x1024" "1600x1200"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 16
Modes "640x480" "800x600" "1024x768" "1152x864" "1280x1024" "1600x1200"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 24
Modes "640x480" "800x600" "1024x768" "1152x864" "1280x1024"
ViewPort 0 0
EndSubsection
EndSection
Note: Edit the "Modes" lines to have only the resolutions you want for each Color
depth. In this configuration your desktop will be as large as the largest supported
mode in the line. Your viewable area is the only thing that changes giving you a
'zoom' affect. If this is not what you want (It probably isn't) make sure the largest
mode on each line is the mode you plan on using for your desktop, the other modes can
be available in case you need a low resolution mode for a game or application. You can
also remove an entire Subsection (Including the Subsection "Display" and
"EndSubSection" lines) if you do not want to be able to use that color depth. Each
Mode must be defined earlier in the XF86Config file under the "Monitor" section. These
should be setup according to what your monitor can support. Most distributions do this
during the install process. See the generic documentation at XFree86 FAQ if you have
difficulty with the modes.
Set up the X server link.
You will need to be root to do this.
ls -l /etc/X11/X
# You should see this as being a link to the vga16 server.
# We'll need to change this. If this link is not here then you
# will need to contact your distribution to assist you.
ln -sf /usr/X11R6/bin/XFCom_i810 /etc/X11/X
# If your X link was elsewhere then use that path in the command
# above.
Start the X server.
If you are already running X you will need to exit and start again. If you are set up
to start X automatically then you will want to restart it by doing a
"CTRL-ALT-Backspace". If X is not running you should start it with a command like
this:
startx -- -bpp 16
The "-bpp 16" tells the server to start in 16 bit depth. You could also use 8 or 24
bit depth.
"CTRL-ALT-KeyPadPlus" and "CTRL-ALT-KeyPadMinus" will rotate through the resolutions
available at the current color depth. For additional documentation on XFree86 or the
XF86Config file please visit the XFree86 FAQ.
Compiling X from Source:
NOTE! This is for experienced Linux users only. Provided are the details needed for
patching and compiling the source, additional expertise is necessary to correctly
install X on your system. If you already have XFree86 3.3.5 correctly installed
compiling and installing the XFCom-i810 binary should not be difficult.
Download the source for the X server from XFree86.org . You will need these files, do
not untar them, simply put them in a temp directory. (Note that this is 40+ MB of
source)
X335src-1.tgz
X335src-2.tgz
X335src-3.tgz
Download the patch from support.intel.com. This file should be called
XFCom-i810-3.3.5.patch.tar.gz
Patch and build the source. Untar the patch into the same directory you placed the
X335* files in and run the build-i810.sh script.
cd path to X335*
tar -zxpvf XFCom-i810-3.3.5.patch.tar.gz
./build-i810.sh
This will build the entire X tree by doing a 'make World'. You can find the correctly
compiled XF86_SVGA server with i810 support located in the directory
XFree3.3.5/xc/programs/Xserver/. This is the same binary shipped as XFCom-i810 in the
binary only distributions. Provided you already have XFree86 3.3.5 installed you
should be able to use this binary by placing it in the correct location and setting up
your links/XF86Config file as detailed above. If you do not have XFree86 3.3.5
installed you should see the References for help.
