Hi Amit,
The processor is the Intel CPU ( Atom ) , the chipset is Intel Poulsbo
chipset .
The disk is SSD.
I used the moblin image creator to create a image to install on device.
And the /dev entries sdx. (small case).
Thanks in Advance.
Rod

What device is this? What is installed on it?
And are the /dev/ entries sdX or SdX? Note small case or upper case 'S'
