Remember that in 6.0 k12 refers their dhcpd.conf that dhcpd-k12ltsp.conf or
something that .
Got it, but here at work, where I am testing 6.0.0 before trying it ah home. . . DHCP is actually running from another server (this has also worked fine with older versions of K12LTSP, so I know it is configured correctly).

Just see in /etc/dhcpd-k12ltsp.conf....
Other thing: with boot it etherboot, in the first lines, before de dots, see
the correct address like: 0x300 or other particular address that offer your
ether-nic and copy to the dhcp conf file.
Port is set (0x300) and I also tried adding the irq settings for the various irq possibilities, to no avail.
I have the option-129 line set correctly.
see in dhcp-k12ltsp.conf.....
I have the right computer name set in dhcpd.conf and also in the
lts.conf for this particular workstation.
Will check again, but I am sure these are correct. . .
