I started playing with the OpenFirmware(I got a SunBlade in the meanwhile). But i'm not able to get an instance of the SUNW,m64B, and as a matter of fact of nothing, as I get a Fast Data Access MMU Miss every time i try the open-dev command. I know I don't need an instance to get the .properties of the device, but I think that MUU miss couldn't be a good thing...
So I kinda got rid of that MMU Miss error, but now, when i try and open-dev the display adapter i get a 0 return code on the stack. The output being something like this.
ok showstack ok " /pci/SUNW,m64B " open-dev 0 ok
Is there anything wrong with this approach. I mean a reason for the 0 return code?
