LinkSys NSS4000 NAS w/ RM7000+PMON2000

Guys,

I've been away from MIPS camp for long time since I have
no good modern MIPS HW at hand.  I found that one of LinkSys
NAS product named NSS4000 is a very good candidate to
port NetBSD.  PLS check out http://www.tmk.com/blog/?p=8
It has 600MHz RM7035C and a variety of modern PCI
peripherals.  The most interesting aspect is that it has
PMON2000 bootloader and HW provides serial console connector
to control.  I guess it's a kind of rare NAS box which equips L2
cache inside.  I hope the product would gain successful share
and would be replaced with bettter processor like MSP8150
(re-badged RM9150) in some future.

Hmm, nice machine. Dual gigabit ethernet controllers and 4 disks...

Do you know if you can netboot it similar to the NSLU2? I was going to
try to find an NSLU2 to play with, but I'm really not smart enough to
do hardware hacking.

This thing could make a really nice box. It's still a little pricey though.

PMON2000 is a feature rich bootloader made by the man who
ported the world first real BSD Unix to R4000.  The port was called
"pica".

Started from the original PMON, PMON2000 has been acumulating
many features by importing code from NetBSD and OpenBSD.  I would
not be surprised seeing NASS4000 even boots ELF kernel on FFS
filesys.

The 64bit OS capable machine could be made in lower price and I feel
puzzling indeed about the wrong combination of HW.

- PM8172 is SysAD32 system controller.  By replacing it with other
  "industory grade" one like Marvell Discovery LT you can buy
  133MHz/166MHz SysAD64 frontside bus w/ DDR333 memory and
  buildin GbE.
- Having RM9120/9220(dual E9K core) could be instant win (but
  PMC-Sierra abandond the entire RM9000 line)
- then moderate replacement choice would be RM9150.
