Flashing the Solo2

[Rob van der Does]

The Solo2 can also be flashed from the internal HDD. If a flashable image is present on the HDD, the box will flash that, even though the VFD reports 'reading USB'.

This has already lead to much confusion.
As the HDD can't always be reached, it would be wise never to have an image on the HDD. Several images (AFAIK most PLi-based images using the so-called 'backup suite') always make a spare copy of the image backup on the HDD. So best make a habit of removing any images from the HDD.
