   Usage: make-fai-bootfloppy [parameter]

   -h       print this message.
   -f file  make a 1440k floppy image

DESCRIPTION
   Creates a boot floppy for booting a FAI install client.
   No arguments are needed but you must be root.
   All parameters are passed to the kernel via append in lilo.conf.

EXAMPLE
    To make a boot floppy for my old SMC EtherCard Plus Elite 16T, I use

    # make-fai-bootfloppy "reserve=0x300,32 ether=10,0x300,eth0"

EOF
