A MAC address consists of a set of 6 (six) funny numbers. The funny numbers are two-digit each,
each digit can be 0 to 9 including A, B, C, D, E and F.

For example:  00 E0 29 30 CC 2F  is a MAC address.
Sometimes there are colons between them: 00:E0:29:30:CC:2F

Good manufacturers such as 3COM, Intel, SMC, Sohoware, D-Link, Netgear,
US Robotics and others have the MAC addresses clearly labeled on the cards.

If not...

Printing out of this optional checklist may prove to be a very useful aid for this project. Setup floppy should come with the card, if not, try the manufacturer's web site, or you could use a substitute [bootable] "setup" floppy here. Insert Ethernet card one at a time in a surplus PC. Power up the surplus PC with the the appropriate "setup" floppy in drive A. Run the appropriate setup program. If the setup program detects the card, it will show you the MAC address of the card.

If you cannot find the setup disk and you are using PCI cards, you can still proceed with the project.

If you cannot find the setup disk for your ISA cards, you may be stuck because you do need to
setup the IO address of the ISA cards, and disable the PnP feature if it has one.
For some very old ISA cards, you can set the IO address with the jumpers on board, so you may still proceed.
