Hi!
I want to enable usb serial ... as it appears on the page: http://www.coreboot.org/GRUB2, but the terminal_output command print it: "Active output Terminals: vga_text Available output terminals: gfxterm spkmodem serial_ * mda_text cbmemc serial audio" then ls command print it: "(usb0) (memdisk)" but when I write "serial --speed=115200 --word=8 --parity=no --stop=1 usb0" this print it: "serial port 'usb0' is not found" My computer is an Acer c710-2847 and it has a chromium OS, I wanted to add the seaBios to install Ubuntu from USB, but I overwrote the flash ROM and now my computer will not start, the seaBios not working. Not even shows me the options to choose... therefore I can't read the USB. I don't know what to do; I don't know how to come back to "Chrome OS" and I can't boot from the USB ...the only option is to use the GRUB2 command-line but I don't know how to use the serial usb on grub2 I thank you so much -- *Juan David Alejandro Cadena Cedano*
