Network Drivers for Ghost 15 Custom Recovery on XPS 15z

I'm trying to create a Ghost custom recovery disk for my Dell XPS 15z.

I've included 32 bit Win7 drivers for the Atheros GBe network and Intel 6230 wireless, but when I boot, start networking services, and try to map a network drive, it says it cannot get the network hardware.

Which drivers are needed to access the network from the Ghost boot?
