To make a bootable floppy on a GNU/Linux system, put a formatted
floppy in your floppy drive and do:
$ cat eb-git-yournic.zdsk > /dev/fd0
where "eb-git-yournic.zdsk" is where you stored
your downloaded ROM image.
On a DOS/Windows system, use the RAWRITE program to write the
.zdsk image to a formatted floppy. RAWRITE is available on
most GNU/Linux installation CDs or on the web.
