In December 2018 I heard from Michal who had added a second IDE port to his V10L:
Out of curiosity I soldered a second header into the board and it turned out to work flawlessly. Simple mod, although requires cleaning soldered pinholes and so it's not an easy task.
A view of the circuit board showing the location of the extra IDE connector. In this example it is partially covered by the 'MAC ID' label.
A view of Michal's modified board. At the right-hand end is the standard DOM fitted to its connector. At the left-hand end you can see the new connector that Michal has added.
The BIOS display with another SSD plugged into the new connector.
Any comments? email me. Added December 2018
