Hi, Thank you very much for the reply, but i would like to ask some more. 1. it seems we can choose which device we want for console output by typing this on kernel command line: console = device , options if i type "console = ttyS1 " is that means kernel will internally link /dev/console to /dev/ttyS1 , and when i do any operation to /dev/console , it is the same as i do to /dev/ttyS1 ? 2 . what means foreground virtual console as tty0 is representing ?
