Re: [Freeipmi-users] SOL after bootup...

[Tudor Holton]

I think this may answer my question:

http://www.bx.psu.edu/~nate/doc/x3550.html 
<http://www.bx.psu.edu/%7Enate/doc/x3550.html> shows how to do it using 
a Debian install CD.

In short the key appears to be to add "console=ttyS0,57600n8" to the 
kernel options on boot.  So a modification to the boot CD would be required.

Also:
# grep GRUB_CMDLINE_LINUX= /etc/default/grub
GRUB_CMDLINE_LINUX="console=ttyS0,57600n8"
# grep GRUB_SERIAL_COMMAND= /etc/default/grub
GRUB_SERIAL_COMMAND="serial --unit=0 --speed=57600 --word=8 --parity=no 
--stop=1"
# update-grub
to the grub startup script.

I haven't tried this yet.  Will get back to you once I've tested it.

Cheers,
Tudor.
