Model-Matrix
Daily updated index of the presence and value of this variable for each model. Last update: 2024-11-21 05:20 GMT.
Showing all models using this variable. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom/rtl) label in the Model column shows which CPU is meant for Multi-Linux models.
Note that this list is merged from Firmware-Probes of all known AVM firmware for a model, including Recovery.exe and Labor-Files.
If the 'Value' column contains '<comp>' the variable is computed at runtime. '<empty>' means the variable is present but empty (rare).
Multiple values typically show a conditional static assignment or different values in different firmware.
