[syslinux] pxe - change default tftp server

[Sebastian Schmelzer]

hello,

if you link from one pxe menu to another one on a different
server via vesamenu.c32 kernel images etc. are still 
searched on the first server. at the moment we have the
ips added to every kernel, append, initrd.. - but is there
a simpler way to change this behaviour? for example to set 
a new tftp server with an append parameter or boot
an entirely new instance of pxelinux on the other server.

thanks,
sebastian
