Cannot boot Volumio 1.51PI in Raspi B rev2

I have Raspbery Pi B rev2 which cannot boot Volumio1.51PI.img. HDMI produce no output and it has only red led on.
Then I have tried the same SD card (without any changes) on my older Raspberry Pi B rev1 and it works like a charm.
Do anybody have any clues how can I debug it?

check if you sd card is connected correctly. i had the same issue with one of my pis. the sd adapter was to loose in the slot, so i didnt have a working connection and it was like no sd card was available.

i bought a special adapter to fix this issue. This adapter is thicker than a regular micro sd card adapter and so it fits more tight in the sd card slot.
