[Dnsmasq-discuss] How to disable bootp and all pxe boot in Dnsamsq?

[Frank]

Hi experts:
     In my subnet there is an bare metal provision system called 
"linmin" which will serve pxe installation, I am also using dnsmasq in 
same subnet as a programmable DHCP server.
     now I want to disable all bootp and pxe stuff in dnsmasq because if 
dnsmasq offers IP during pxe installation, the linmin system will not work.
     I see from the man page simply ignores parameter will disable the 
functionality, so I add "dhcp-boot" in /etc/dnsmasq.conf, unlucky the 
dnsmasq cannot start error message:

Starting dnsmasq:
dnsmasq: missing parameter at line 87 of /etc/dnsmasq.conf

     So what should I do to disable it? thank you.
