Hi
The driverpack included in E2B is rather old and does not have the latest chipset drivers.
See the page https://easy2boot.com/make-an-easy2boot-usb-drive/adding-latest-dpms/
for instructions on how to update the drivers.
I have checked the 1405176 driver pack and it does have the 8086 8c82 driver in the INI file..

so try that.
