Hi,
I am getting following message through the serial output. The message is SDRAM TEST Passed. After that I am doing MTRR Initializing. In the serial output I am getting some character. Can any one help me in knowing, why I am getting junk character like this "ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ"
Thanks, Siva

Almost looks like the baud rate is changed somewhen after Ram6. What baudrate are you using?

also on some of these superio if you just reload the baud register, even with the same baudrate, it will send lots of garbage output.
It could be that, which is harmless.

I have added some debug message which corrupted the values in some resgister. Now it is working fine.
Thanks, Siva
