You can specify the parameters on Run a program menu like this:

 scsi(0)disk(0)rdisk()partition(1)netbsd OSLOADOPTIONS=s

See sys/arch/arc/arc/machdep.c:mach_init() function
for other options.

I guess 4200 has a different video from 2200 and etc.
arcdiag output might help, but I think it has VXL based
video and it is not supported yet. (no hardware info?)

Unfortunately, as far as I know no one is working on SMP support
for NetBSD/mips (not only arc), and maybe it requires a lot of work.

EISA support should be trivial and it is on my TODO list
(I also has Express5800/240 with EISA DPT RAID), but
no work is done yet...

There is some code for EISA interrupts for NEC machines
in sys/arch/arc/pci/necpb.c, so I guess only thing we have
to do is implement some machine specific EISA part like
alpha and i386 etc.
