No OS

Obtain a Fermi Linux floppy disk from PREP counter in FCC3W or from Yolanda at WH8NW. This can be used no matter what OS you intend to install. Boot the machine to the "Choose a Language" screen. Then press Ctrl-Alt-F4. Look for the lines near the bottom of the screen that starts with the string "<6>eth0:". Near the end of the line should be a string of 6 hexidecimal numbers separated by colons. This is the MAC address.
