I know you're joking. Well, that your instructions are correct but that your point is that "fixing" a demo unit is not worth the considerable trouble. But is it not possible to extract a flash image from a firmware update downloaded from slimdevices.com like squeezebox2_130.bin? Is it not the case that a firmware update re-writes the device ROM (EPROM? I don't really know what I'm talking about) with N bytes from the downloadable firmware file, starting at byte M in the firmware file (perhaps discarding some error checking bytes interspersed in the file)? Is it not the case that the firmware for an SB2/SB3 resides in something like EPROM, the settings in something like NVRAM, such that someone might, just might, be able to extract the ROM image bytes from squeezebox2_130.bin and use that to "fix" a demo unit? Not that I would ever bother, I'm just intrigued as to how this works. :-) -- peterw http://www.tux.org/~peterw/ Free plugins: 'AllQuiet' (http://www.tux.org/~peterw/slim/AllQuiet.html) 'Auto Dim/AutoDisplay' (http://www.tux.org/~peterw/slim/AutoDisplay.html) 'BlankSaver' (http://www.tux.org/~peterw/slim/BlankSaver.html) 'ContextMenu' (http://www.tux.org/~peterw/slim/ContextMenu.html) 'DenonSerial' (http://www.tux.org/~peterw/slim/DenonSerial.html) 'FuzzyTime' (http://www.tux.org/~peterw/slim/FuzzyTime.html) 'KidsPlay' (http://www.tux.org/~peterw/slim/KidsPlay.html) 'KitchenTimer' (http://www.tux.org/~peterw/slim/KitchenTimer.html) 'PlayLog' (http://www.tux.org/~peterw/slim/PlayLog.html) 'PowerCenter/BottleRocket' (http://www.tux.org/~peterw/slim/PowerCenter.html) 'SaverSwitcher' (http://www.tux.org/~peterw/slim/SaverSwitcher.html) 'SettingsManager' (http://www.tux.org/~peterw/slim/SettingsManager.html) 'SleepFade' (http://www.tux.org/~peterw/slim/SleepFade.html) 'StatusFirst' (http://www.tux.org/~peterw/slim/StatusFirst.html) 'SyncOptions' (http://www.tux.org/~peterw/slim/SyncOptions.html) 'VolumeLock' (http://www.tux.org/~peterw/slim/VolumeLock.html) ------------------------------------------------------------------------ peterw's Profile: http://forums.slimdevices.com/member.php?userid=2107 View this thread: http://forums.slimdevices.com/showthread.php?t=72358 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
