According to this doco: 'Novell Documentation'

to enable BOOTP to work, I configure this in the DNS/DHCP console for
the Subnet I want and click ok. My questions are -

Do I need any other nlms on the server for this to take effect if the
workstations are on the same LAN?

Will this only take effect on the subnet that I specify, or all subnets
that this server administers?

Once the PXE agent has been rebooted and is no longer requesting the
BOOTP address, how long before the address can be released (From what I
can see, BOOTP addresses are permenant, but I am assuming there is some
watchdog that clears unused connections)?
