NLB Image and Freesat Card:
With NLB, In order to get a valid Sky/Freesat Card to work, the CAMs are automatically started, all you need to do is press the green button and make sure that mgcamd or mbox is selected. - this means that you just have to plug the card in - there is, however, a glitch that happens every 20 or seconds or so. To fix this, you need to select the mbox cam in the NLBPanel plugin. It may also be necessary to add your boxkey into the /var/keys/newcs.xml file.
To find your boxkey, you need to check the system status screen in your sky decoder - you will see a system id number, which is 10 digits long, e.g. 0007559782. This number is in decimal, and the newcs.xml file needs the same number, but in hexidecimal. Convert the number to hex, and pad it out with leading zeroes to make it 8 characters long, e.g. 00735a66. This is the boxid that needs putting into the newcs.xml file.
NLB Image and EPG:
Sky uses the closed OpenTV standard, which has been reverse engineered by a number of people, most notable ambrosa in the creation of e2_loadepg. This background work has resulted in the creation of crossepg. Unlike other systems and providers, Sky only transmit now and next information with each channel, and if you want to get full browsable EPG information, you need to go to a specific channel - this is great for receivers with very low memory, like the original sky boxes, as they can extract the data live from the stream. It does lead to very slow navigation though. Crossepg can extract and store this information from the EPG stream, which is broadcast on a radio channel called "Sky EPG Background Audio".
Crossepg can be downloaded from http://www.crossepg.com/ for the DGS based images. In order to get the download working, you need to select the crossepg.plugin, and hit the menu button. Under system, you can select which channels you want epg information downloaded for. Then 'Start Downloader' to download for the first time.
It is likely that this will lock up. This is because the epg downloader uses quite a lot of RAM, and there is little left. You can overcome this by adding and enabling a swapfile (see disk and swap section below).
When the box starts, it takes a short time for the disk to come online, so I'd recommend setting the crossepg download (under the 'Automatic actions' menu option) to happen in the middle of the night, not after boot.
Interesting Files
The following files on the distribution may be of interest:
/var/S59_userboot.sh - This is a script which is run during every boot, and may be modified by the user to launch his own programs.
/var/db.dat - This is xxx
/var/keys/newcs.xml - This is the file in which you may place your boxkey for your valid Sky Card.
Verification of Installation
Lots of information about the installation can be seen by connecting a serial cable to the box during boot.
