I've overlaid the files from "Drivers Update 1 patch" on the Novell Client
1.0 for Windows Vista installation set.

However, when I attempt to install, Novell Network Client device software
is flagged as NOT digitally signed. I'm am not seeing this with the plain
Novell Client 1.0 for Windows Vista install.

Perhaps I'm misunderstanding the instructions contained in the readme:

"The files in this package can also be overlaid on top of a Novell Client
1.0 for Windows Vista installation set such that when SETUP.EXE is run to
install the Novell Client, you will be installing the core 1.0 Client and
the updates contained in this package in one operation. To update the
installation set with the file in this patch set, copy the directory
structure over the top of the "Novell Client for Windows Vista 1.0"
folder."
