If you have a network connection, one thing you might try is to do a base install of Woody, using it's
floppy disk install images. You'll need 6 floppies, 1 each for boot and rescue, and 4 for the drivers. It's basically like the Sarge net-install, but on floppies. You could also do a base isntall in this way using a Woody CD instead of a network connection. The only caveat versus the Sarge installer is that you'll need to know about the hardware on the machine beforehand - what NIC module to use and such.
Once you get to a base install, dist-upgrade to Sarge and you should be good to go.
