Re: Installing NetBSD over SoL

I guess this should be changed to 'why consdev doens't work'

From freenode#netbsd, "felicity" kindly noted:

] something like this: options
CONSDEVNAME="\"com\"",CONADDR=0x3f8,CONSPEED=9600   # untested
] if you can get the dmesg output somehow, you can find the necessary
i/o address. [speaking of the 0x3f8]
] i think 3e8 is most likely actually, although for ports above com2
there doesn't seem to be a definitive standard

I'll give this a shot if I can't find a place in my BIOS to change
where the SoL 'listens' on, but it still fails to answer
the question why consdev com3 doesn't work when it seems the behavior
I expected was the intended behavior.

I wonder if NetBSD has a static CONADDR= which is incorrect for my board?

Any thoughts? -- Ben
