While it's true that you can use PXE without the BOOTP options, they are still useful in that environemnt. Specificly, setting BOOTP causes your IP address to be set via BOOTP/DHCP which is nice. At first glance, I think this change is fine for PXE. Also, there are people who use other methods. If nothing else, non-i386 or amd64 machines use the older style net boot stuff. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
