How can you run RIS image setup manually?

I have a laptop that has a PCMCIA Nic which of course means I can't boot off
of it and run a RIS install in a typical manor but I was wondering if it was
possible to run the RIS image setup manually.

I have created a DOS boot disk that is able to connect this laptop to the
network and I can see the RIS image. From previous experience I have been
able to integrate the drivers of the PCMCIA nic into a slipstreamed image of
XP and W2K so when it comes to the GUI portion for the Network Setup I am
able to join the domain fine.

Because of these two reasons I naturally figure that if integrate these
drivers into my test W2k and XP images I can use the one RIS image that I
use for all my installs. The only problem is that I don't know what I
should run on the network to start Windows setup.

I thought it might be as simple as going to my
\\RISSERVER\REMINST\Setup\.....\i386 folder and running Setup.exe, but that
file does not appear to be there - nor any of the DOS mode WINNTx.exe
files? How can I start the RIS welcome screens manually?
