Hi All,
Currently I have got Xpenology and other operating systems running on my spare DS1511+ Synology diskstation.
It seems that other diskstations like the DS1010+ , DS710+ and some others also have a fully working VGA port which let's you acces the bios and use it as a normal pc.
I have carefully made an back-up of the flash drive module (which contains the grub bootloader) , which is inside the diskstation, and mounted directly on a internal USB header on the motherboard.
