FreeBSD 9.X network installation using PXE+TFTP (not NFS) !

[Egoitz Aurrekoetxea]

Hi!,

Take a look,

http://postfixquotareject.ramattack.net/freebsdpxehowto.pdf

Now by default all is built with BSD installer although you could always build you’re own disks with Makefile.sysinstall…..

Tell us if you have more questions…

Regards!
