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.
