1.0 Preparing the disc (skip this part if install on OF 1.0.5 as it will only support partition 0 bootstrap)
First in OS X you need to format the drive with 1 UFS partition and no classic drivers, make sure you set the partition map as "Apple Partition Map".
Then go to the terminal and type :
$ pdisk /dev/disk3
Then create a partition map that's something similar to this one:
Partition map (with 512 byte blocks) on '/dev/disk3' #: type name length base ( size ) 1: Apple_partition_map Apple 63 @ 1 2: Apple_HFS hfs_boot 4096 @ 64 ( 2.0M) 3: Apple_UNIX_SVR2 canaille 7937235 @ 4160 ( 3.8G) S0 RUFS k0 / 4: Apple_UNIX_SVR2 swap 1572864 @ 7941395 (768.0M) S1 SFS k0 (swap)
Now format that drive:
$ newfs /dev/disk3s3 & newfs_hfs /dev/disk3s2 & sync & sync
You need to put the 'ofwboot.xcf' bootstrap on the HFS partition. So mount it and copy it
$ mkdir /Volumes/hfs_boot & mount /dev/disk3s2 /Volumes/hfs_boot
Get the ofwbooot.xcf file from the installation CD:
$ cp /Path/to/ofwboot.xcf /Volumes/hfs_boot/ofwboot.xcf
1.1 Booting the installation cd.
Go to the open firmware and type:
0 > boot cd:,\ofwboot.xcf netbsd.macppc
(cd:,\OFWBOOT.XCF NETBSD.GZ with macinbest's boot cd for "Old World" machines)
The cd should now boot.
Select reinstall sets. Use customs sets, otherwise the installer will format the drive with disklabel which will render the HFS bootstrap useless.
1.1.1 Things to remember about the installer
Backspace won't work in the shell unless you do:
# stty erase ^? (^H on the Gigabit G4, just hit your backspace key)
1.2 Setting the boot sequence.
1.2.0 Longer, better method
See this post: http://mail-index.netbsd.org/port-macppc/2005/02/28/0014.html and create the bootbsd.of file on the hfs_boot partition. Make sure to set the boot partition properly. This technique allows for better flexibility with some hardware bugs (this one corrects some video issues). It can be used to slow down the boot process of machines that have drives with high spin up delays.
Once you have the bootbsd.of copied, do this in the OF:
0 > boot hd:,\bootbsd.of # If it worked 0 > setenv boot-device hd:,\bootbsd.of 0 > setenv boot-command boot 0> setenv auto-boot? true
1.2.1 Simple boot method
0 > boot hd:,\ofwboot.xcf hd:3,/netbsd # Or 0 > boot hd:,\ofwboot.xcf
1.2.2 Outdated method
This method is out dated, see below. It is kept here because it could be useful on other macs
Go to the OF and type:
0 > setenv auto-boot? true 0 > setenv boot-device ide0/disk@0:2,\ofwboot.xcf 0 > setenv boot-file ide0/disk@0:3,/netbsd 0 > reset-all
1.2.3 Single User Boot
0 > boot hd:,\ofwboot.xcf hd:3,/netbsd -s
You should now be booting in your fresh NetBSD install.
If not, verify you've set the boot-device and boot-file properly and accordingly to your partitions.
2.0 Configuration
See Notes on Installing and Using NetBSD.
2.1 CPU Optimization
Add the following to /etc/mk.conf
For the PowerMac G4 and G3:
CFLAGS+=-mcpu=750 -mtune=750 -O2 -pipe -fforce-addr CXXFLAGS+=-mcpu=750 -mtune=750 -O2 -pipe -fforce-addr COPTS+=-mcpu=750 -mtune=750 -O2 -pipe -fforce-addr PKG_OPTIONS.bash=multibyte static # Important for bash
For the Cobalt Qube:
CFLAGS+=-march=mips3 -mtune=r5k -mabi=32 -O2 -fforce-addr CXXFLAGS=-march=mips3 -mtune=r5k -mabi=32 -O2 -fforce-addr
2.2 OpenFirmware Colors
$ cd /root $ wget http://trac.mlalonde.net/basedoc/computing/netbsd/cmap.tbz $ gunzip cmap $ chmod +x cmap $ nano -w /etc/rc.local $ /root/cmap 0 255:255:255 >/dev/null 2>&1 // Text Color $ /root/cmap 15 0:0:0 >/dev/null 2>&1 $ /root/cmap 255 0:0:0 >/dev/null 2>&1 // Background
Note that if you're going to do this manually you should first set a text color that's *readable* with both black and white backgrounds
You can get the source here /basedoc/computing/netbsd/cmap.tbz or here http://geekrants.com/francis/archive/cmap.c
2.3 Kernel Config
Current configuration file for Fripouille (PowerMac G4 DigitalAudio).
2.4 Mounting AppleParitionMap? formated drives under i386
Use apmlabel (available in 5.0 as of this writing) to convert the APM to disklabel.

Quick guide to install completely from CD if you can't mount the hfs partition on another volume to copy the OFWBOOT.XCF
Boot from the CD Enter the shell Use the pdisk utility on the CD to partition your HD with: - HFS partion for ofwboot.xcf (2MB, MUST BE HFS) - / FFS partition for NetBSD (rest of disk) - swap partion (also FFS, 1-2x the size of your physical RAM) newfs your / partition (ignoring errors) and mount it on /mnt mkdir /mnt/etc and create an etc/fstab file for your / and swap partitions, (using cat or echo since no editor will be available) umount the HD, and invoke sysinstall CHOOSE REINSTALL SETS, and proceed with the installation when the install completes the re-enter shell and re-mount the HD edit rc.conf using sed (still no editor available) to rc_configured=YES shutdown system and reboot from the CD to the HD e.g. 0 > boot cd:,\ofwboot.xcf hd:3,/netbsd Your system should now boot multi-user pkg_add hfsutils via ftp (and rehash) mount the CD on /mnt and cd /mnt hformat and hmount your hfs partition, e.g. hformat /dev/wd0d && hmount /dev/wd0d hcopy ofwboot.xcf :ofwboot.xcf This copies ofwboot.xcf from the CD to your HFS partion Only now can OpenFirmware boot from your HD reboot into OpenFirmware: setenv boot-device hd:2,\ofwboot.xcf setenv boot-file hd:3,/netbsd
