I've already looked at those manpages which is what led to my post to  
the list.
fdisk and installboot would seem the tools needed to update the mbr,  
however,
this is a system that already boots to a serial console. If this is  
not the
correct discussion list to be asking such questions, I can try else  
where.

The issue I have is that if I use 'consdev com0' at the boot prompt,  
should I
not be able to redirect console output to the serial port on a PC for  
any
kernel regardless of whether as long as their is driver support for  
'com'?

What I'm getting at is it is not entirely clear nor documented in an  
obvious
place (such as INSTALL.txt).
