execute the script calling it like this :

/var/patchME XX XX XX XX XX XX

The XX XX XX XX XX XX is the desired MAC ADDRESS. Do not use colons to separate the bytes.
example:

This is ok --> /bin/patchME 00 09 34 21 21 21

This is not ok --> /bin/patchME 00:09:34:21:21:21

Congratulations ! Mac address permanently changed.

You need to change it with the Linux trick,

How to change MAC address in Linux

First find the physical MAC address of your machine by running the following command :

$ ifconfig -a | grep HWaddr
eth0 Link encap:Ethernet HWaddr 00:80:48:BA:d1:20

The hexadecimal numbers in blue denote my machine's MAC address. Yours will be different. Learn how to use the ifconfig Linux command.

Next, login as root in Linux and enter the following commands -

# ifconfig eth0 down
# ifconfig eth0 hw ether 00:80:48:BA:d1:30
# ifconfig eth0 up
# ifconfig eth0 |grep HWaddr

1) Flash image.
2) Telnet to reciver.
3) Type: patchME 00 09 34 XX XX XX
Change: XX XX XX
To any walid hex value.
4) Reboot reciver to make bootloader changes to become active.
5) Telnet to reciver again, and check mac to be sure it changed.
6) Type: ifconfig |grep HW
7) If you have a valid DMM mac you should be able to use any image.

Original DM500 have MAC like these...

00:09:34:20:xx:xx
00:09:34:21:xx:xx

xx:xx can be anything, but the 20 or 21 I think are very good to be sure to have a 100% good MAC address.

Use at own risk.
