There are already very similar question - still unanswered -- here: http://lists.gnu.org/archive/html/help-grub/2011-12/msg00093.html
I also have Intel-AMT-enabled motherboard (ASUS P8Q67-M DO). Linux kernel found two serial ports: one real, and one SOL port: ttyS1 at I/O 0xf0e0 (irq = 17) is a 16550A Linux serial console works fine on both.
On boot in grub command line i enter the command : > serial --port=0xf0e0 but receive the error: "Unknown serial port".
Why GRUB can't see this port? How to find correct port number? Or there are some special features of SOL serial port preventing it's discovery by GRUB?
