with the small machine (phenon 4, 8Gb), and vmware, the sistems is
slow... and the MB does
not accept more than 8GB.  Besides I would need a version of each
operating system for VMWARE..
and I do not know if vmware can be used for free. If even in a school
you can, in other places
you cannot, so I would cope with several platforms... Here I run a
business based on FreeBSD,
and the less different solutions the better...

I use PXE because it is in the firmware of the MB... (almost always
have)... some very old
computers, does not boot anything but: floppy, cd, or HD... I choose
CD..  one CD,
boot all machines...  Netboot is great too...

Strange  I have been using it in a day basis, and never had problems
with that... the 
machine sometimes suffer power failure (3 months, or 1 month period)..

I use FreeBSD 8.2 in zfs...  with zmirror, and daylly snapshots...  so I
can go back anything
till 5 days ago...

Anyway, thanks for the information
