Thanks, your example really helped me get it working.  Your example was 
only missing the tag on the dhcp-boot line.

# Special boot hosts
# PXE response for non-iPXE clients
dhcp-match=set:ipxe,175 # iPXE sends a 175 option
dhcp-boot=tag:!ipxe,ipxe.pxe

# PXE response for host 'mythbed'
dhcp-host=bc:ee:7b:25:3b:15,set:mythbed,mythbed
tag-if=set:mythbed-ipxe,tag:ipxe,tag:mythbed
dhcp-boot=tag:mythbed-ipxe,http://minimyth2/conf/mythbed/mythbed.ipxe

# PXE response for host 'mythliv'
dhcp-host=38:60:77:9c:6b:1d,set:mythliv,mythliv
tag-if=set:mythliv-ipxe,tag:ipxe,tag:mythliv
dhcp-boot=tag:mythliv-ipxe,http://minimyth2/conf/mythliv/mythliv.ipxe

I really appreciate the help.  I can now EOL my local copy of tftp, 
bind, and dhcpd in favor of dnsmasq!
