ATI FireGl 7800 on IBM A31P no driver???

It should work using "radeon" driver.
"X -configure" must create working config file.
If not - post outputs of "uname -a" and "X -version" (omiting hostnames to stay safe from internet)

why radeon drivers???

uname -a : Linux (name) 2.4.27-2-386 #1 Wed Aug 17 09:33:35 UTC 2005 i686 GNU/Linux
X -version >t.txt won't work so here the important info I think
Xfree86 Version 4.3.0.1
X protocol version 11, Revision 0, Release 6.6
Build Operating System: Linux 2.6.8-16.0508-2 i686 [ELF]
OS Kernal : Lin8ux version 2.4.27-2-386 (gcc version 3.3.5)
hope it'll help

btw, the "Radeon" driver is the same as for "FireGL' driver in the ATI site .
fglrx_6_8_0-8.24.8-1.i386.rpm

opensource "radeon" driver from x.org is not same proprietary "fglrx" from ati technologies site.

BTW FireGL 7xxx is NOT supported by ATI Technologies drivers...

I didn;t get what I should do now after your remark

there is nothing to download form x.org about the redeon driver
I hope I'm wrong

X.Org                            Version 6.9.0

can you give me more detail how to do it???
I have no problem to raise point , Ijust need it to work and I'm new in Linux I dont have much time to learn now
10x

I want to stay with debian!!!

how do I Install Xorg or update it to newest version???

Don't.

Or rather... If you decide to update to something newer, do so by going "slightly unstable":-). The Debian stable branch is _always_ severly out of date. It is so bad that one really has to doubt the viability of using the stable branch for anything serious (strange as it may sound). If one wants to stay "in the family", Ubuntu 5.10 is nice:-).

But back to your issues:
I'm not that certain that XFree86 version 4.3.0.1 _doesn't_ contain the opensource driver, on the contrary... I'm quite certain that it does contain it.
What you need do to start using it is to edit your configuration file (I only have a "surviving" Debian 3.0 with XFree86 version 4.1.0 on, so ... this is _probably_ the same) either named /etc/X11/XF86Config-4 or /etc/XF86Config (the former should take precedense over the latter, in case both exist), an make usure you use either Drtiver "ati" (which is supposed to automagically select the correct driver for Mach* Rage128 and Radeon (which, as Andrew has mentioned already, contain support for your FireGL 7800), or use Driver "radeon".
If you have X running, you'll of course need restart it after changing the file.

Does this not work for you? What errors do you get in the /var/log/XFree86.0.log file?

Radeon driver - Yes. FireGL 7800 - No.

https://support.ati.com/ics/support/KBAnswer.asp?questionID=18896
7800 - No. Old XFree86 - Yes.

X -configure selects driver named "ati" which automagically will use "radeon" driver when needed.

Minimum to support FireGL would be upgrading to XFree86 4.4.0

You may wish to use X.org 6.9.0 for extra eye-candy like real translucent windows and hardware rendered fonts (this one is included in Ubuntu)

Why I am suggesting Ubuntu - http://distrowatch.com/stats.php?section=popularity !!!

Ah. Bummer. So likely no go then. Oh well.... always the bad thing with Debian stable... Should've checked the fine print, it's been a while since I fiddled with 4.3.0 last (I had to resurrect the Debian mentioned above... Horror.:).

Why I'm suggesting Ubuntu? Has nothing to do with popularity, and all to do with 1) functionality (it's simply well come together), and 2) the expressed desire to stay Debian.... Ubuntu is the child that got it right:-).
