Thanks to some great suggestions & help from Simon via his blog
I managed to ‘see’ a Pi alive. Looks like the O/S is good and now I just need to run some updates/config.
For some reason, I could not see the RPi on my laptop. I can on an HDMI TV. Turns out both the laptop and Pi are HDMI *out* only – this is why it works on a TV with an HDMI input.
[Note to self (after a very expensive ethernet and ‘gold plated’ 3m HDMI lead from Asda) Farnell is *far* cheaper for everything needed than Maplin, Asda etc]
So, tomorrow, I’ll be buying a powered USB hub so I can connect a mouse and keyboard to the PIs, and the Pi to the bedroom TV(!) and begin the O/S stuff.
Painful progress today, but progress nontheless.
Simon also recommends XMing for emulation/control.
– I guess i’ll be battling with that soon!
