On my version of Toast (4.1.1) for the Mac OS, under the 
Format menu, it gives me the options:

Files and Folders
Audio CD
Disc Copy

I've been using 'Files and Folders' and I'm pretty sure 
I've created the CD successfully.

-----

When I execute the boot cd:ofwboot.xcf, netbsd

it prompts me with "Boot:" and I'm assuming that the netbsd 
part of the command did not make it through.

-----

I'm am still able to make it to the 'root device' input on 
the ofwboot.xcf loader if I leave out the netbsd part of 
the boot command. My problem is that I don't know what the 
'root device' is, what the 'dump device', nor where to find 
out this information. 

Is there a way to find out what's up with my partion 
scheme, including the BSD partitions, before I load into 
the boot loader?

Your help is greatly appreciated. I cannot say this enough 
times. I know I am on the verge of successful installation, 
just I realize my own shortcomings and knowledge about my 
Mac devices, partitions and such.

Thank you again.

Hans
