I regained my old Apple iBook G4 from around 2005, which I liked very much back in the days. As I didn’t find any usable Linux distribution, I ended up installing OpenBSD 6.8. It is quiet simple to install, but be sure to have a look at the marvelous installation notes.
- Sound (speaker + earphones)
- Network, DVD, USB
- Wireless LAN
- Power off
What’s not working:
- Display brightness regulation
- Standby, suspend and hibernate
I chose a DVD as the installation medium and used an image which contains all file sets: install68.iso. It’s a good idea to plug in the network cable during the installation, because WLAN won’t be available due to missing firmware.
At boottime, just hold the
f keys to enter the open firmware. At the boot prompt, type in the following:
boot cd:,ofwboot /6.8/macppc/bsd.rd
Now a standard OpenBSD installation starts, there is not much to say about it. For disk partitioning I went with Whole disk → Custom layout :
# size offset fstype [fsize bsize cpg] a: 1024.2M 4096 4.2BSD 2048 16384 12958 # / b: 1024.2M 2101664 swap # none c: 28615.8M 0 unused d: 10240.5M 4199328 4.2BSD 2048 16384 12958 # /usr e: 1024.2M 25171776 4.2BSD 2048 16384 12958 # /var f: 1024.2M 27269408 4.2BSD 2048 16384 12958 # /tmp g: 14276.4M 29367072 4.2BSD 2048 16384 12958 # /home i: 1.0M 1 MSDOS
NOTE: Don’t delete the MSDOS partition
i, or your system is unable to boot!
If you haven’t used wired network during the installation, you now have to install the needed firmware for graphics and wireless lan by yourself:
Now let’s check if it was successful:
# fw_update -i Installed: bwi-firmware-1.4p5 radeondrm-firmware-20181218
The installation is now complete, let’s head over to the configuration.
Console keyboard and display settings are done via
1 2 3 4 5 6 7 keyboard.encoding=de.nodead keyboard.map+="keycode 10 = less greater bar" display.screen_off=60000 display.kbdact=on display.msact=on display.outact=on display.vblank=on
I added the pipe symbol to the
< key, accessible with
Advanced Power Management
To get the maximum “performance” out of your machine, use apm:
# rcctl enable apmd # rcctl start apmd # apm -H
Sound works out of the box, it just needs to be unmuted:
# sndioctl output.mute=0 # sndioctl output.level=.5
I have a german Apple keyboard layout, which looks like that:
Getting a useful keyboard mapping is a little bit of an adventure. First create a file called
1 2 3 4 5 6 7 8 9 10 Section "InputClass" Identifier "XKB Defaults" MatchIsKeyboard "yes" Option "Protocol" "standard" Option "XkbRules" "base" Option "XkbModel" "macintosh" Option "XkbLayout" "de" Option "XkbVariant" "nodeadkeys" Option "XkbOptions" "terminate:ctrl_alt_bksp" EndSection
I ended up adding the following lines to my
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 # fixes for a german ibook g4 keyboard layout xmodmap -e "keycode 20 = ssharp question backslash" xmodmap -e "keycode 22 = BackSpace BackSpace Delete" xmodmap -e "keycode 24 = q Q at" xmodmap -e "keycode 26 = e E EuroSign" xmodmap -e "keycode 35 = plus asterisk asciitilde" xmodmap -e "keycode 46 = l L at" xmodmap -e "keycode 66 = NoSymbol NoSymbol NoSymbol" xmodmap -e "keycode 94 = less greater bar" xmodmap -e "keycode 108 = Mode_switch NoSymbol Mode_switch NoSymbol Mode_switch" # mode_switch + escape = right mouse button" xmodmap -e "keycode 9 = Escape NoSymbol Pointer_Button3" xkbset m xkbset exp =m # window manager xsetroot -solid darkgrey exec fvwm
The keyboard mapping is now close to a standard german ISO layout. If you need keycodes,
xev is your friend. I mapped the bottom right enter key to Mode_switch. As there is no right mouse button on the keyboard, I’m emulating one with Mode_switch + ESC.
Don’t forget to install
Now all that’s left is to enable and start xenodm:
# rcctl enable xenodm # rcctl start xenodm
And we are done!
CD / DVD usage
To mount a CD / DVD:
# mount /dev/cd0c /mnt
Unmount and eject:
# umount /mnt # eject /dev/cd0c
The eject key (
F12) does work too ;)
- Switching the console is a little bit tricky the first time you try it, because you first have to press
ALTand hold them, then press and hold
Fx. Xorg is on position 5.
- Sometimes WLAN stops working, give it a kickstart:
sh /etc/netstart bwi0
- If the machine is loosing its wlan link too often, just leave a ping running in the background:
ping -i 10 <host>
