Hello!

I have some trouble with the NetBSD/MacPPC installation.
I try it with all versions betwenn 1.4 - 1.5.1 and get always the 
same error on my G3 Pro (Yosemite 350MHz, revision A)

After i boot from the cd i select "Install NetBSD to hard disk" and 
get this Message:
"I can not find any hard disk for use by NetBSD".
The disk is the original 6 GB.

What can i do ?

I heard that some of the first G3 Pro shipped with buggy IDE 
controllers could that be the reason for the above described problem ?

Greetings and thanks for help,

Martin
