D820 - nVidia Quadro 120M - XP64 - WHERE IS THE DRIVER ?!
Hi everyone,
I'm doing programming work on a D820, and need to migrate our software to 64-bit. I have 2G RAM and will migrate to 4G shortly. The transition from 32-bit code to 64-bit code will be hard enough without introducing the vagaries of Vista, and it's server-based anyway, so we picked XP64 as the target OS.
I checked out Dell support for the drivers:
http://support.ap.dell.com/support/downloads/driverslist.aspx?c=au&l=en&s=gen&ServiceTag=&SystemID=LATITUDE%20D820&os=WW1&osl=en&catid=&impid=
AND THERE IS NO VIDEO DRIVER !
Some searching produced nVidia drivers (nv_162.18-xp64) that claimed to support the Quadro NVS 120M (alias GeForce Go 7400), but these refused to install - claiming that they could not find a suitable driver. After some investigation, I found that the D820 GPU has a unique identifier (01D8), different from the standard 120M (01DB). I added two lines to nv3_disp.inf to add the Dell version of this GPU, and the installation worked.
Hurray ! I now have a working video driver !
However, the next step was to enable my second monitor - and this is where it all goes pear-shaped.
No matter what I do, I either get no display at all on the second monitor, no display on my laptop monitor, or a cloned display with the laptop screen resolution (native: 1680x1050) set to the that of the secondary (1280x1024).
Anyone out there solved this ?
DELL, WHERE IS THE XP64 DRIVER FOR YOUR PRODUCT ?
DO I HAVE TO SELL IT, AND BUY SOME OTHER COMPANY'S PRODUCT THAT IS SUPPORTED ?

It should install as a GO7400.I don't use XP, but in Vista x64 this has worked without any issues.- Thanks for that EmJay !
But I've already "been there, done that". See:

The standard driver does not install because the Dell has a different DeviceID, and the link to the modded INF file is broken.
As you can see, I modded the INF file myself, and it installs, but the dual screen mode is busted - and this is essential because my programming takes up two screens - which is one reason why I got the 120M in the first place.
