1. Introduction

This document has a very specific purpose; to help people who are failing to get X working on Intel's i810

graphics chipset (hereafter "the i810"). It is written by a beginner (me), and it is imagined that it will be of

use primarily to other beginners. The author would be flattered to hear that he has helped anyone more skilled

than he. Furthermore, I know that the i810 works with XFree86 3.3.6, but I personally have not trod that path.

My experience comes purely from XFree86 4.0 (hereafter "X4.x") and the i810/agpgart support available in

the 2.2.18 and 2.4.x kernels, and consequently this HOWTO tackles that solution, or procedure, alone. The

instructions that follow were written to the 2.4.x compile tune, but the procedure is similar enough to be

translatable to the 2.2.18. Use your head, as Tony Buzan would say, and read the READMEs to be sure of

any required alterations of method.

Even though I know this procedure works I feel obliged to point out that what I have recorded here is mostly

that which I have worked out in my own bumbling way. It may well be that others know a quicker and more

efficient method than that which follows. If so I will be happy to hear from them. As I mentioned previously,

the i810 will work with XFree86 3.3.6, if one also uses some drivers designed by Intel for the task (namely

XFCom_i810−1.2−3 and I810Gtt−0.2−4) but, in the interests of Linux purity, and of course knowing one

does not have to use Intel's software, I recommend the method detailed here. It does not need Intel drivers.

Finally, no introduction would be complete without the following words of caution; this HOWTO should be

regarded as a 'bare bones' set of instructions and should therefore be followed with all relevant README

literature to hand. What follows is not exhaustive by any stretch of the imagination, and needs, at least for

beginners, said README stuff.

1. Introduction

2. Down to business

Note: Do everything that follows logged on as root.

There are three distinct stages that need not be followed in the order listed here (please feel free to use your

imagination). Said stages are;

· get and compile kernel 2.2.18 or 2.4.x (including mknod agpgart stuff)

get and install X4.x

· nimbly tweak XF86Config

2.1. Getting and installing X4.x

The first stage is of course listed only as a guide for those who have perhaps tried getting XFree86 3.3.6

working with the i810 and failed, or perhaps those who have not even heard that X4.x supports the i810 and

have been struggling vainly with their XF86Config file. I suppose the majority of people who find these

instructions useful will have already loaded X4.x. You lot can skip this bit. Anyway, if you do need to know,

X4.x can be got from; ftp://ftp.xfree86.org/pub/XFree86/4.0/binaries

But before you rush ahead and download away you must first be sure which version of X4.x suits your

system. So download Xinstall.sh on its own and run (from within the folder containing

Xinstall.sh ):

sh Xinstall.sh −check

The results will direct you to the correct folder within the above mentioned URL from where the appropriate

files for your system can be downloaded.

For a basic installation and to save time downloading one needs only the following absolute necessities,

without exception (the others are optional and when included in the install process, I feel, increase the

chances of things going wrong for the unwary and inexperienced):

extract[.exe] Xdoc.tgz Xvar.tgz

Xbin.tgz Xfenc.tgz Xxserv.tgz

Xlib.tgz Xfnts.tgz Xmod.tgz

Xman.tgz Xetc.tgz

Now knowing which set of files are suited to your system you can go ahead and download whichever suits.

Then install with the following command (from within the folder containing freshly downloaded files):

sh Xinstall.sh

If you have been good everything will proceed smoothly. You will be asked some questions which the

README file can explain/answer better than I. If something doesn't work as expected I refer you to the far

more detailed, aforementioned README file, which you should definitely peruse. As a newbie I always read

the readme files before downloading, installing, compiling and even getting up from my seat to go to the

toilette. You can never be too sure.

2. Down to business

i810 with XFree86 4.x HOWTO

That is the end of this stage.

2.2. Get and compile kernel 2.2.18 or 2.4.x (including

mknod agpgart stuff)

You can get either kernel from ftp://ftp.kernel.com . Of course, read everything called README while you

are at it. (In the README literature that comes with the 2.4.x kernel, there is an important note about where

to unpack the source. Make sure you read it.) Put the kernel source file in /usr/src/kernels , and then

run the following compile sequence, which I learned from a linuxnewbie article (to which you should refer if

my directions are not clear enough for you, however it is specific to 2.2.x kernels). It can be found at the

following address; http://www.linuxnewbie.org/nfh/intel/compiling/kernel_update.html . Of course, the

location of the still−packed kernel is not really relevant, it only matters that it is unpacked to an acceptable

location. OK, now for the commands:

tar −xzvf /usr/src/kernels/linux−2.4.x.tar.gz

or if you downloaded the better compressed bz2 version

bzcat /usr/src/kernels/linux−2.4.x.tar.bz2 | tar xv

and watch the screen spew out pages of information about what's happening. When it is finished it will have

created a new linux folder.

OK, so, change to the new directory:

cd linux

and begin the compile process proper...

make config

Or preferably

make menuconfig

There's also make xconfig , but you haven't got X running, or you wouldn't be reading this. So that won't

work. And I'm embarrassed to mention it in such an imperfect fashion but there is also something like make

oldconfig but I can't find any reference to it in my books. In any case I am not addressing it here, though I am

sure the procedure for it is very similar to that which follows for make menuconfig , should you be awkward

and want to use it.

Now, I have gone through three text based kernel compiles ( make config ) and know how long winded they

are. I reommend make menuconfig instead, which requires only that ncurses be loaded (you don't need X)

and you will be taken through the pretty face of kernel recompilation. I loaded ncurses during a custom install

of Red Hat 6.1, but I forget exactly at which stage that option is available. Otherwise ncurses is, I'm sure, on

your distro's CD in rpm format, so if issuing make menuconfig just produces errors, install ncurses and try

again.

2.2. Get and compile kernel 2.2.18 or 2.4.x (including mknod agpgart stuff)
