When using an etherboot or BOOTP boot ROM network booting is
quite straightforward:
The client PC contacts the DHCP or BOOTP server to get its IP
address and the name of the boot image file (ltsp kernel) to transfer down and
execute. The client PC uses TFTP to download the ltsp kernel from the boot
server; hence the reason for the TFTP daemon.
In PXE booting, things are little different. The
PXE client must first download the network bootstrap program (nbp) or PXE
loader. The PXE loader will in turn transfer down the ltsp
kernel. Why is this so? This is just the nature of PXE.
The PXE loader or nbp must not be greater than 32K in size;
otherwise, you'll get the unintuitive "PXE-E3A TFTP too many packages"
error.
In the case of PXELINUX, the PXE loader is the called
pxelinux.bin. Pxelinux.bin reads the default.cfg file to determine
the ltsp kernel to download. If you find the PXELINUX approach too
complicated then try the PXE-Etherboot
approach.
