Tried running a MinnowBoard Turbot 2 Quad with a Flotsam lure and a m-SATA SSD with Windows 10 on it
of a 2.5 Amp USB wall-wart with a USB to barrel connector cable.

It boots almost to Windows - it paints the login screen and photo, then reboots. There must be a current
demand surge at that point in the OS startup that is just too much for the wall-wart. And another
wall-wart I tried did get past that point, but tanks when I load the system - like starting the browser.
And removing the lure and running Win 10 from an SDCard worked for the short time I was testing it.

I am going to take some current profiles to see what the instantaneous demands are as an OS boots up, and
even to get a sense of the comparative profiles for different OS's, and if different configurations or
driver/display setting make a difference.

The bottom line is that an otherwise perfectly functioning install will apear to give flaky boot or
other startup issues if the power available is just a hair short of the instantaneous demand. And the
failure looks just like the software is hiccoughing, or loading a bad driver, or any number of the usual
suspects, because the process gets a fair way into getting to the desktop.

So verify your power supply is rated for the 5.0 volt 4 Amp recommended - while less may work, it could
give you grief that looks like it is not your powersource.

Note: the 2.5 Amp that is commonly avaialble with the board is sufficient for just the bare board and maybe
some low-power lures, but I am running a Quad Core, for one, and a pretty high-power demand Flotsam lure with
power hungry daughter cards installed. So now we know - 2.5 Amp is insufficient - just. And presents a failure
that can fool you into thinking there are software gremlins at work.
