grub2 output to both console and serial

[William Thompson]

I am not on the list, keep me in CC.

Is it possible to output to both the vga console and the serial terminal as
with older versions of grub? I thought I did this at one time but am unable
to do this now. At this time, the oldest grub version I used is
1.96+20080724-16

For grub1 (not grub2) you can add the following lines to you menu.lst

serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1
terminal --timeout=10 serial console

Add to kernel command line

console=tty0 console=ttyS0,115200

And add ttyS0 line to inittab

This setup favours serial over console. If you prefer to favour
console switch tty0 and ttyS0,115200 parts of the kernel command line,
and switch serial and console in the terminal line.

Regards,

Daniel

I knew grub1 would do it. Are you saying that grub2 will not?
