For a live cd depends on what you need to run. Might be better off custom building one of your own from Knoppix or Ubuntu. Knoppix has lots of support for nics. Seems good with ndiswrapper but not sure on the windows inf file needed. May have to use a usb flashdrive and ad the addition items needed.
