the SS4 and SS20 both have on-board video, the SS10 has a card in it.
All 3 have no video, no keyboard connected.
Shouldn't serial console be fall-back when no keyboard is detected?

On my SS20 I see:
output-device=screen
input-device=keyboard

I have the same on my SS4. I tried setting input and output  device both 
to ttya, but no avail. I end up with a black screen if I attach a 
monitor... so the parameters do something, but not what I expect.. seems 
like serial is somehow dead/different.
Luckily I still have the 113W3 cable, even if the LCD Monitor doesn't 
properly sync the size like the old CRTs, so the last line is missing... 
but enough to test and boot.
