[syslinux] Transform a normal boot on a network boot

[GL]

Hello, there is a transparent and standard way to boot from the network, a
media  that is bootable (cdrom, floppies) ?  It is possible to interpret the
standard boot sector and use a network boot loader such as pxelinux or
other, to tell where to find, and the proper way to load the correct files
from the tftp server ?



An example would be appreciated using "common" boot disks, for example the
dos boot floppy obtained with format a: /s and the windows 2000 cdrom.



Thank you in advance.
