As you all know, the Ati Catalyst drivers are BIG.

The version I will describe here, 5.12, is 35 Mb unpacked.

This is proably not an optimized slimming down, i just deleted all the stuff that's obviously not needed.

When you install the Ati driver, it usually unpacks itself first into a C:\Ati directory.

Go there and you will find something like this:

A couple of directory's called:

BIN
CP
Driver
WDM_ALL

And a list of files like these:

AtiCim.bin
AtiCimUn.exe
CheckVer.exe
data1.cab
data1.hdr
data2.cab
DrvUI64A.exe
ikernel.ex_
install.ini
issetup.exe
layout.bin
makensisw.exe
psapi.dll
Setup.exe
Setup.ini
setup.inx

You can delete ALL the files in this directory. This is the attended setup tool which has not only zero value for us, but even for those of us who manually install these drivers it has very little added value.
The real stuff is in the subdirectories of this directory.

I can be short about the BIN directory: you don't need it. Delete it.

The CP directory is for, guess what, the Control Panel. I don't fiddle around with this directory, I just move them to the directory where I install it from my guirunonce section of the unattended setup.
The Control Panel is not needed unless you do a lot of tweaking with games. I find I hardly ever use it myself, but YMMV.

The Driver directory is where the real driver sits, and this is the part that we'll take a look at now:

You'll find one subdirectory called 2KXP_INF and a bunch of files:

C2_28472.INI
CX_28472.INI
data1.cab
data1.hdr
data2.cab
Driver.dat
Driver.DLL
ikernel.ex_
INSTALL.INI
layout.bin
Setup.exe
Setup.ini
setup.inx
setup.iss
_setup.bmp

Delete the files and continue into the directory 2KXP_INF.
Here you find another subdirectory called B_28899 (This is where the actual driver files are).

atiiseag.ini
C2_28472.inf
CX_28472.cat
CX_28472.inf

I have no idea what the ini file does, but it doesn't take any space at all so I just leave it. The inf files are what you need, and the cat file is secure signing for the drivers. I recommend leaving all these files in place.

IMPORTANT: Before we proceed into the 2KXP_INF directory, take note that you do not change the name of this directory. The inf files point to the name of this directory to find the driver files, so if you change the name of the directory driver setup fails.

The 2KXP_INF directory contains these files (in my case at least):

ati2cqag.dl_
ati2dvag.dl_
ati2edxx.dl_
ati2erec.dl_
ati2evxx.dl_
ati2evxx.ex_
ati2mdxx.ex_
ati2mtag.sy_
ati3duag.dl_
atiddc.dl_
atidemgr.dl_
atifglpf.xml
atiicdxx.dat
atiiiexx.dll
atikvmag.dl_
atioglx1.dl_
atioglxx.dl_
atipdlxx.dl_
atitvo32.dl_
ativcaxx.cpa
ativcaxx.vp
ativckxx.vp
ativcoxx.dl_
ativvaxx.dl_
ativvpxx.vp
oemdspif.dl_

These are the actual driver files. Unless you know something I don't, I recommend you leave these files alone.

So, in short: You only need the files in the Driver\2KXP_INF and it's subdirectory for the driver, and the CP directory if you also want the control panel.

In case you have an All-in-Wonder card, you'll probably need the WDM_ALL directory too.

You'll find these three directories like these:
AVS_T200
WDM_NSP
WDM_SP

And a bunch of files.
data1.cab
data1.hdr
data2.cab
ikernel.ex_
install.ini
layout.bin
Setup.exe
Setup.ini
setup.inx
WDM_ALL.dat
WDM_ALL.dll

You can delete the files, and use the subdirectories.

Hope this helps you slimming down your unattended CD's.

Cheers,
Crusty
