Pick one as your primary. Bootloader and kernel and messages can echo to both consoles, but init scripts will only echo to one console (your primary console). The order of the "console=" in the kernel line in grub.conf determines which is the primary. You can have multiple "console=", ie "console=ttyS0,9600n8 console=ttyS1,9600n8 console=tty0", but only the primary display will show init script output.

But still don't have ideas for how to get the messages after the "Welcome to RedHat Linux..." line to show up. /dky On Mon, 11 Jul 2005, Keegan, Gordon wrote: > I've had the same issue under Lilo as well as grub and haven't found a > solution for either one.
