Bring up a liveCD or moral equivalent and run SLIP, then do any of many
networked-backup variants?  SLIP at 115200 is only about 1% of a 10Mb
Ethernet, but that may be enough to be useful, especially if you
compress.

Alternatively, maybe move the DOS disk to the other machine and copy it
there with dd or moral equivalent?
