Hello I have an ASUS T100TA [1] and I'm trying to use the wifi device with the Debian Installer for Stretch Alpha 5 .
As explained here [2], the wifi device requires a proprietary firmware and its nvram-file, a UEFI configuration variable from /sys/firmware/efi/efivars. Loading the firmware in the DI is not a problem but I'm unable to access the efivarfs interface. Using a tty console in the DI, I can see that the directory /sys/firmware/efi/efivars is there but it is empty. Mounting the efivarfs in this path [2] fails with the "no such device" message, and lsmod doesn't show the efivars and efivarfs modules, which I suppose are required. So, is it possible to access the efivarfs interface and retrieve the required nvram-file inside the DI environment? If you answer, please add my e-mail address in CC because I'm not subscribed to this list. Thank you very much.
