Most new Servers or Workstations
aren't equipped with a floppy drive anymore, but from time to time I
need to boot from a floppy drive. And I don't want to burn a CD each
time I need to boot from a floppy drive.. so the solution is tftpd32
and PXELINUX. With those 2 tools I'm able to boot disk images from the
LAN.
You need tftpd32 from Ph. Jounin (
http://tftpd32.jounin.net/) and PXELINUX, which is a part of the SYSLINUX package (
http://syslinux.zytor.com).
Tftpd32
act's as DHCP and TFTP server (of course you can use another DHCP
Server) while PXELINUX provide booting Linux from the network.
You can download the 
ready-for-use package here.
Directory structure of this package:
root dir                -     executable files
bootimages       -    the uncompressed (*.IMA) disk images.
pxelinux.cfg        -    the PXELINUX config file
my simple default pxe configuration:

Change the Current Directory and the IP settings, so that they fit your needs.
The result should look like this menu:
