The Intel Pro/100M is a peripheral component interconnect (PCI) network interface card (NIC). There are similar network adapters from Intel that are integrated, but whether you have a PCI or integrated adapter, finding the driver is not difficult as it is usually in one of a few common places.
Disc
The most common place to find the driver for the network adapter is on a CD that came with the product or with the computer if the card is integrated. If you bought a motherboard separately which has the network card on board, the disk should have come with the board.
Online
If you don't have a CD with the driver on it, you can almost always find Intel drivers from the Intel website or the website of the computer retailer under the support section.
Windows
Microsoft Windows usually comes with driver support for most hardware compatible with into Windows. After installing the device, Windows will find it and assign it a Windows driver that should work with it. In some cases, the driver may not work but for something as simple as an Intel network card, that should not be a problem.
