G'day

I'm trying to install NetBSD 3 on my trusty old Powerbook 3400c and 
during the initial
process I come across few problems that I'm hoping someone be able to 
help me with:
(better if anyone who already done this can send me some tips :-)

I can access my Open Firmware prompt with no problem (which is version 
2.0.1)
However, I'm not certain if :
    -    the installation instructions say *I can* or *can't* boot 
directly from NetBSD ppc 3.0 cd

and if I can boot directly from the NetBSD cd,
    -    is it then possible to use the entire hdd without installing 
any MacOS partitions?

So far, I am unable to boot from the CD, but I can't tell if its due to 
these instructions listed at
http://www.netbsd.org/Ports/macppc/SystemDisk-tutorial/#The Boot device 
entry 
<http://www.netbsd.org/Ports/macppc/SystemDisk-tutorial/#The%20Boot%20device%20entry>

Basically, if I can boot with NetBSD cd, then I can use the pdisk to 
partition the hdd.


Also, the suggested partition structure is as shown below.
        HFS or HFS+   over 100 KB
        A/UX Root       at least 20 MB - not readable from MacOS.
        A/UX Swap      RAM size
        A/UX User       at least 200 MB
        A/UX Free1     at least 200 MB
        HFS                 any size
        UFS                 any size

There are 3 partitions with HFS/UFS... are they necessary? I suppose 
this could answer my first
question if I need to install MacOS partition!!! if so, where does the 
Mac OS go?

cheers
