The wiki is being retired!

Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to Contributions welcome!




In your boot/grub/menu.lst add the following:

serial --unit=0 --speed=115200
terminal --timeout=15 serial console

Change --unit=0 to --unit=1 for the second serial port (COM2).

Linux kernel command line


console=ttyS0,115200 console=tty0

to send debug output to both the serial console on COM1 and to VGA.

Linux login prompt

In /etc/inittab add/enable a line like this:

T0:23:respawn:/sbin/getty -L ttyS0 115200 vt100

Change ttyS0 to ttyS1 for COM2.
