For a floppy boot 'recovery/emergency/utility' resource, I highly recommend 'tomsrtbt' Linux-On-A-Floppy [LOAF]. It includes drivers for many cards and will grab a DHCP address on bootup.
1) Tomsrtbt stands for: "Tom's floppy which has a root filesystem and is also bootable."
2) Design goals: As much stuff as possible on 1 floppy disk, keep it self contained, build under itself, try to make it behave like a normal system rescue and recovery functions get priority
Go to http://www.toms.net/rb/
DOS Utilities are available in the download to create the floppy.
Caveat: You have to like & be somewhat comfortable with the *IX command line. [ mount, ftp, fdisk, cp, df and such ]
Good Luck !
