Both.
Working dnsmasq.conf
-------
$ cat /etc/dnsmasq.conf
# interface=eth0
pxe-service=123456789, "Install Linux", pxelinux,0
dhcp-range=172.24.0.63,proxy
## dhcp-range=172.24.0.30,172.24.0.40
dhcp-option=vendor:PXEClient,6,2b
dhcp-boot=bootfilename.bin,nero.lan,172.24.0.54
log-dhcp
enable-tftp
tftp-root=/srv/tftpd
port=0
-------
Main difference against previous version is the 'pxe-service=' line.
The 172.24.0.63 is the broadcast address ( my network is 172.24.0.0/26 )
To have that seen working, I did have to reboot a physical computer.
So, yes, your advice for DHCP test client is still welcome.
