The simplest way is to get a tool to help. The best tool I know of for this purpose is a boot disk maker from PowerQuest that comes with their DriveImage Pro application. You can download a trial version from www.powerquest.com/freestuff/trials.
The Boot Disk Maker will walk you through the process step by step. It will take the real mode network drivers from your Windows 2000 Server CD and the NDIS2 driver from the driver floppy for the adapter. You can point the utility at drivers you've downloaded from the Internet.
NDIS stands for Network Driver Interface Specification. This is Microsoft's proprietary open standard for network interfaces. You'll need the real-mode driver, which is NDIS2. Look for something called LanMan drivers or MSDOS driver. The driver name will have a .DOS extension. There may or may not be a snippet of a Protocol.ini file accompanying the driver that describes how to use the driver token.
