ок, i made these settings in WinNTSetup.ini
Drivers=drivers
driverdir=drivers
And i get an empty field in Add Drivers for every new boot of winpe.
The field is not empty if you run WinNTSetup again without rebooting.
It might be better to make a special folder called drivers as well as for unattend files
And is it possible to make the drop-down list of all ISO files the same as for Unattended files? Let's call this folder for example - iso/distr/win... etc
