Dell e6410 factory custom BIOS won't allow wireless network drivers to install

[scocope]

I just received in 11 Dell e6410 i7 laptops. Wireless network drivers will not install and Dell Support Driver Detect does not detect that the driver is missing (I was able to get a generic driver disk to install a driver for a Ethernet cable connection) though it detected all others. They are from the VA and upon looking up the service code there was a "Custom BIOS" installed (http://www.dell.com/downloads/global/ser...i_bios.pdf)

I'm pretty sure this is the problem; the VA, to protect patient information, made sure wireless network drivers would not install. Anyone know of a way around this? Or will the easiest solution be new motherboards?
