Does anyone know how i can 'map' my zs chip as Kapil suggested to me?
(below)

I picked up the firmware books, but i'm still at a loss on how to do that.

I'm trying to boot netbsd and it freaks out when it can't map the zs
chips in my ultra1/170e.

suggestions? 

thanks,
-Alfred

I recommend buying `Writing Open Firmware Client Programs' from
http://www.firmworks.com

Easier is to look at /usr/include/sys/openprom.h on your Solaris
machine.

The reason for that is the `zs' chip is not being mapped at boot time
by your PROM. You can workaround this by using `iomap' family of Forth
commands before you boot.
