Re: ddb input via IPMI virtual console

[Brian Buhrow <buhrow%nfbcal.org@localhost>]

	Hello.  Sorry, my description wasn't clear.  
Since you hav an IPMI capable server, you should be able to turn serial
port redirection on in the BIOS such that com1 (from NetBSD's point of
view) becomes a virtual port which is accessible using the ipmitool
program.  You would do something like:

ipmitool -H 10.10.1.3 -U ADMIN -I lanplus sol activate
	After you enter the password, you should be connected to the virtual
serial port where you can see output or type input.  Since this is a serial
port as far as NetBSD is concerned, DDB should work.
	This is a separate session from your virtual console, so you can run
it in a separate window.

Change the username and IP address shown above to match
your setup.


To get NetBSD to use that serial port as a console, you'd do something
like:

cd /usr/mdec
installboot -v -o speed=115200 -o console=com1 /dev/boot<device> bootxx_ffsv<version>
