There's an Intel 10 Gigabit X540 Adapters Driver for Windows PE5

http://en.community.dell.com/techcenter/enterprise-client/w/wiki/5029.winpe-5-0-driver-cab

but not for Windows PE 10

en.community.dell.com/.../11530.winpe-10-driver-pack

unless Windows PE 10 already has native support for the Intel 10 Gigabit X540 Adapters Driver ?

(This useful for deployment via SCCM 2012 R2 and newer, since it uses Windows PE 10)

Thanks
