You should be able, though getting this message, to install BESR without the recovery disk having this driver. This message is more of a warning that the driver validation test suspects a needed network driver is missing from the recovery disk. Since it appears that this is an application level device driver that is missing, and does not relate directly to a network card, you should be able to ignore it. I would though, test your recovery disk by booting this machine and verify that the system’s hard disk and network devices are usable.
