This may be way off but here goes.
The PC that you are installing the network card into probably has a built in LAN interface with a CAT5 port (802.3). Under normal circumstances, this port would be connected to your high speed modem (DSL or cable etc.). I say "probably" because even back in the old days of ME, it was common practise to connect to the Internet via a high speed modem and most motherboards had one built in.
You would not normally connect two network devices to each other and then use another port as your main Internet connection. I'm not even sure it could be done.
To accomplish your task, you should have a router, either wired or wireless or best of all, one that has both wired and wireless ports. This device acts as a hub to which you attach your PCs and other devices either with a CAT5 cable or wireless. The router becomes the device your ISP 'sees' and accepts the assigned IP address from the ISP. In turn, it becomes the device that assigns IPs to the devices on your LAN. It sends and receives data from your devices and their assigned IP addresses and sends and receives data from your ISP at the IP assigned by your ISP.
Typically these routers have 4 ports to accommodate 4 devices (PCs, printers, etc) and the devices can be connected wireless or wired. In your case, you probably want to connect your ME PC through a wired connection and the portable would likely be wireless. Many portables come equipped with a wireless card.
I appreciate that this doesn't really address your problem with installing drivers but, if I am correct, you don't have to.
