Hi All

I have a question relating to the cmdline option ie root=console=dev/null.
When we specify the console=/dev/null how is this implemented. One more
question  is there anyway we can change the cmdline options after the Linux
kernel boots i.e. if I want to specify the console = /dev/ttyS0. Can anybody
help me in understanding this cmdline.

Thanking you in advance
Regards
Aman

What else do you want to specify? The baudrate?

console=/dev/ttyS0,9600

I set this in my bootargs variable for ppcboot...which gets passed in as the bootline and eliminates the need for me to type anything during the boot sequence.

setenv bootargs console=/dev/ttyS0,9600 root=/dev/nfs rw ... ... ...
