Computer help! Please!!!?

Where can I find a free download for a pcmcia driver for a compaq v5204nr notebook? I've updated the chipset drivers, and I've checked HP's site. I've searched everywhere I can think of. I've even tried to install the hardware manually, and it it tells me the drivers aren't installed and can't find it when I search from there. I can't use my mobile internet adapter until I find this driver, and I'm out of idas. Please help!
