Hi!
Thanks for your suggestion. I tried that but nothing worked out.
i am working on NetBSD. So i mapped the memory from 0xA0000 to 0xBFFFF. From 
this memory mapped I tried to read a single byte from the device and also the 
word but of no use. I get only 0xFF.

My first aim is to get the Green Light(LED) on the monitor to glow.
How to get that thing.

Regards,
Rishabh
