Here are the main points for installing the JMK firmware(s):
Make sure you use Mugwump's CD (burn it to CD and boot from it, don't try and install it from the hard drive).
Make sure you have a compatible motherboard and the other bits as explained in the post here: pages.php?page=20
Make sure the flash memory is erased (by using the erase command if needed, as explained here in more detail below).
Make sure you give the router plenty of time to boot up after installation (up to 5 minutes) .
Make sure you just press <ENTER> for the MAC addresses - do not actually enter any MAC addresses.
Full instructions to convert to the JMK UPnP firmware
These instructions only apply to Mugwump's CD version 5.2 onwards.
At present this only applies to Origo’s (or SafeCom's) ASR 8000/8001/8400 models and may work with other generic Conexant routers but it does NOT include WIRELESS.
Note that the JMK and Origo/Safecom are separate companies and so using JMK firmware on a non-JMK router is not fully approved by the manufacturers.
Download Mugwump's Origo Repair CD and follow the instructions below to the letter…
** BEWARE - YOU MAY VOID YOUR WARRANTY BY PERFORMING THIS OPERATION **
**** IF YOU ARE AT ALL UNSURE ABOUT DOING THE FLASH, DON'T DO IT! ****

* The pair of pins may be labelled "JP1" or "JP4". The jumper may have different labels according to the model and manufacturer (in most cases there will only be one set of pins).
Log in to your router with http://10.0.0.2 : User name is "admin", the password is "epicrouter"
You should see:
Customer Software Version: JMK_22.214.171.124_100_01OCT04
Enter the ISP user/password details as supplied by your ISP. Submit & save the changes and reboot (the router will normally take 15 to 30 seconds to reboot).
Thanks go to Mugwump for adding the firmware to the now famous repair CD!!
