             My misunderstanding of the sequence here.  When I saw  
the menu
             and blue screen I figured I was in yaboot.

             Agree, seems inconsistent.  Is there a way to manually  
reformat
             bootstrap partition and reinstall those files?  Am  
thinking maybe
             there was some hiccup with YDL installer.  The rest of  
the install
             seems fine, I can do any Linux stuff I want once it's  
booted
             from the CD-ROM.

             Did those things, boot-device setting now reads:
             boot-device        ultra1:,\\:tbxi        hd:,\\:tbxi
             (ie, there are 2 values on that line, only the first one  
changed)

             Here's the startup screen (blue):

             First stage Yellow Dog Linux bootstrap
             Press l for Yellow Dog Linux
                      m for MacOS
                      x for MacOSX
                     c for CDROM
             Stage 1 Boot:

             When I choose 'l', I get this (black screen):

                 Can't open device </pci@80000000/pci-bridge@d/pci- 
ata@1/@0/disk@1:0>
                 /pci@80000000/pci-bridge@d/pci-ata@1/@0/disk@1:2,\ 
\yaboot.conf: Unable to open file, Invalid device
                 Can't open config file
                 Welcome to yaboot version 1.3.11
                 Enter "help" to get some basic usage information
                 boot:

                 'x' -- works, boots OSX
                 'c' -- works, boots installer from CDROM
                 'm' -- odd, screen blacks out for a second, then  
returns to blue menu, no error

                 I think that would be 2d line of above, starting  
with "/pci@800..."
