RISCServer 4200

Hello everyone!

My RISCServer 4200 is finally back and operational after a serial 
console stunt that I won't be repeating. So, I hacked together what I 
believe is necessary for the 4200 to boot. I run the kernel and get a 
blue screen, which from reading the archives I believe is normal. 
However,I'm not having any luck getting a real serial console to work. 
I've built a GENERIC, PCCONS, and RAMDISK kernel, none of which show 
any screen activity nor any serial activity on my Portmaster. I have 
created this "COMCONS" kernel config, like so:

*** GENERIC     Thu Jan 22 18:54:36 2004
--- COMCONS     Thu Jan 29 02:14:39 2004

And it's now compiling. My questions are:

1. ) Will the ARC Firmware pass a "console=com1" parameter to the 
kernel with the "Run a program" menu option? It doesn't seem to pay any 
attention to that flag, if it does. Perhaps my kernel is borked?
2. ) It seems like in the list that someone said video on the 2200 was 
fixed. I assume (perhaps incorrectly) that the 4200 uses the same video 
subsystem as the 2200, but perhaps at a different location. Does video 
work or not?
3. ) Since I expect this thing to boot soon, my next project is 
tackling SMP support for -arc, as well as adding support for the EISA 
bus and my DPT RAID card in this beast. Is there anyone out there 
that'd like to give me a few pointers on what all needs to be done to 
make this port SMP-capable? It is my understanding that a majority of 
the code is shared with other MIPS projects, like pmap.c, but I don't 
really know of any other MIPS SMP machines that are supported.

Thanks!
