i m trying to write a MDA driver for C&T's 69030 chip. The PCI card is memory
mapped. starting from 0x0800000 with the memory size requirement of 16MB.

How to access the Character Buffer of MDA  which lies in the lower address
 map of 0xB000-0xB7FF ?
I m able to read and write to the registers.

I tried writing the a word of data(0xaa55) at 0x0800a0000 but on reading it
back i got 0xFFFF.

What is this problem? am i reading the memory properly.....
Please help.
