B+ Differences[edit]

This troubleshooting guide currently doesn't mention the model B+, so I guess that when it says something like:

Check that you have correctly written a Raspberry Pi image ... browse for the following files:

*   bootcode.bin
*   fixup.dat
*   start.elf amongst others

Does it mean a good NOOBS Micro SD card that came with a new RPi B+ might be allowed to not have start.elf while it does have bootcode.bin and other files/dirs?? Or are there specific things to do with these cards before they can be used? Are there other places this page needs updating for the newer models?

There are other places. The red LED is no longer directly connected to the 3.3v rail, but driven by the RST output of an APX803 supervisory circuit. As a consequence, a blinking red LED on the B+ is not a direct consequence of a brownout, but a warning that the 5v power rail is dropping below 4.63v. I'll add a sentence to that effect.
