Yes it is different behavior. Previously, I saw that the rev D device was
contacting the tftp server. There were log entries and I could see that it
was looking for mvp.bin rather than dongle.bin. Now, after my editing
change, the rev D device doesn't contact the tftp server at all.

No it does not have that feature.

I have 2 MythTV servers (for testing) on my network and I have a rev H
MediaMVP too. So I have been exploring this functionality.

Obviously, I don't know what I'm talking about... but it seems like prior
settings were indeed saved because the device had been used on my network
previously and it worked without any special DHCP server setup (until I
edited that file).

Yes, the 2nd one is a rev H.

Is this config file anywhere close to being correct? I have questions about
- domain-name-servers
- option root-path
- option broadcast-address
- option routers
I'm not sure of the values that go in those options.
$ cat /etc/dhcp3/dhcpd.conf
ddns-update-style none;
option domain-name "my-example.com";
#option domain-name-servers ????????????; #how do I assign my ISP's name
servers dynamically?

max-lease-time 2419200;

subnet 192.168.2.0 netmask 255.255.255.0 {

option subnet-mask 255.255.255.0;

hardware ethernet 00:xx:ae:xx:a2:xb;
fixed-address 192.168.2.13;

option root-path "/tftpboot,rsize=4096,wsize=4096,nolock"; #what path
goes here???
}
}
