OK, so here's an updated
build with the tools you need for testing/installing drivers.
First you'll want to backup your host driver(s) with
SmartDriverBU like this:
Run the program and select View --> View all drivers and de-select all but the one(s) you need and save these to your to hdd.
In your new project folder, create a sub-directory
* in %GlobalTemplates% named PENetwork (ex. C:\lx012209cxs\Workbench\Common\PENetwork) and copy your driver backup there:
*As Lancelot just reminded me, If you run wb and go to PEN's script ui, there is a cool feature now called Explore
that auto-magically creates this folder
for you and opens it so you can just drag/drop your driver folder(s) in the open window! Very cool

- I'm all for removing any semblance of thinking required by the user

I just wish it would find the needed drivers and copy them there as well

- Seriously, this is pretty darn cool and don't forget, one of the great unsung features of PEN is that it will load
any type of drivers here not just NIC's.
When the project is run, any drivers in this folder should be auto-detected and installed by PENetwork
--
Alternately, you can try installing from PE using DriverImportPE (included in build):
Run the program and choose import from folder (.inf) method
Browse to your driver backup and select the .inf (can be the one in %GlobalTemplates%)
If the driver shows good, just click Import Driver and wait for final result.
After DriverImportPE wraps up, you'll need to run PENetwork (in quicklaunch) and hopefully get an active connection, you can test in Opera. Good luck!
