I tried our suggestion.
The effect of this is that the client DOES receive some boot
information. Only the menu item is held back.
I checked with wireshark and it seems that an 'empty' PXE menu is returned.
The VMware Server bios fails with "PXE-E76: Bad or missing multicast
discovery address".
Your suggestion does mean I can create tags for groups of clients and
customize the menu by hiding/showing options. Very usefull feature
for the future.
I've also tried this:
domain=lan.basjes.nl,172.21.13.0/24
dhcp-range=net:known,172.21.13.0,proxy
dhcp-host=00:0c:29:99:4E:92
dhcp-ignore=#known
dhcp-boot=net:known,pxelinux.0
But that had the same effect as
pxe-service=net:known, x86PC, "Boot PXElinux", pxelinux
