Troubles installing drivers for ATI 4670 (mobility)

I have been having troubles installing drivers for the ATI 4670. I tried using Mobility Modder to install the latest drivers but I keep getting the error:
'Driver Install: The INF file was not found'
Any ideas? As I currently have no drivers on my Laptop and therefore cannot play games on it which kinda sucks.
My Laptop is a DELL Studio XPS 1640 btw.
Thanks a lot.

'Driver Install: The INF file was not found'

I get this error whatever way I try to download them.

You don't get it. AMD has stopped developing newer mobility drivers so you have to use the Mobility Modder Software to mod the desktop drivers to be able to work on laptops, otherwise you're stuck with 3 year old drivers.

try to use the radeon drivers for the 4670 not the mobility drivers

It was sarcasm rangers
Only the mobility drivers work for the mobility cards.
I need Vista 64 preferably, but Vista 32 is fine if no 64.

Yes.

Bump.
None of the above posters have understood my problem yet.
Please help!

well, you could download the newest catalyst for desktops and mod the inf file to add your card (should use the same driver as the desktop 4670)

i hope you know how to do this

give a few minutes, it takes a little while to type

okay here are the steps

1) download the newest driver for the non-mobility 4600 series (ie catalyst 9.8)
2) start the installer, when it is done extracting cancel the setup (as it would not find you drivers anyways)
3) go to directory "C:\ATI\Support\9-8_vista64_win7_64_dd_ccc_wdm_enu\Driver\Packages\Drivers\Display\W76A_INF"
4) open CH_85216.inf in notepad
5) under the [ATI.Mfg.NTamd64.6.0] (the one with all of the video card names) add "ATI MOBILITY RADEON HD 4670" = ati2mtag_R7X, PCI\VEN_1002&DEV_9490"
6) go to control panel->administrative tools->computer management
7) go to Device Managemer, find the display adapter
8) right click->update driver
9) click browse my computer for driver software
10) choose let me pick from a list
11) click have disc
12) change path to "C:\ATI\Support\9-8_vista64_win7_64_dd_ccc_wdm_enu\Driver\Packages\Drivers\Display\W76A_INF"
13) hope to hell your display adapter is there and works and click ok

now this worked for the old mobility radeons (Xk series and X1k series, might work for yours)

Thanks a lot for the help mindless!
Will try this out in a minute and report back with updates, appreciate it.

I tried out the steps you gave and it's saying:
'The best driver software for your device is already installed
Windows has determined the driver software for your device is up to date.
Standard VGA Graphics Adapter'
What the hell? I have no graphics driver so how can it be up to date, plus it's not even saying that I have a ATI 4670, just VGA Graphics Adapter.
Any idea?

did you save after step 5

for step 5 use
"ATI MOBILITY RADEON HD 4670" = ati2mtag_R7X, PCI\VEN_1002&DEV_9488"
instead of
"ATI MOBILITY RADEON HD 4670" = ati2mtag_R7X, PCI\VEN_1002&DEV_9490"

i had the wrong number (its hard to find these unless you actually have the card)

Still getting the same error as before:
'The best driver software for your device is already installed
Windows has determined the driver software for your device is up to date.
Standard VGA Graphics Adapter'
'

Okay this is quite wierd now. I managed to get the driver install to work using a slightly different method and now when I 'run' 'dxdiag', it says the driver version is '8.15.0010.0217' and in Device manager --> display properties it says the driver version is '8.640.0.0', I thought the newest version was 9.8 or something? If so, why does it say these different versions?
Thanks.

I can assure you TheGreatGreatApe that I checked their FAQs and their forums many many times.
If you are so sure that I need to 'RTFM' then please link me to where my problem is explained in some detail as to fix my problem. Then again, which manual would you like me to read?
Thank you.
