# Runs in audit mode, before sysprep: adds the VirtIO drivers from the virtio-win
|
|
# ISO to the driver store. The devices are not present during the installation
|
|
# (it uses ramfb and e1000e), so pnputil only stages the packages; they survive
|
|
# /generalize, and Windows binds them on the first start with virtio devices.
