The pupose of this tip is to describe how to install Gentoo on a Mac Mini, Intel machine.

PLEASE NOTE: This is a work in progress, I'm trying find least painful way to get Gentoo onto a Mac Mini, based on the notes I've found on th e net.

Installing the sw

  1. Get bootcamp
  2. Divide HD, I picked 20GB for the Gentoo part
  3. Insert the Gentoo CD when bootcamp ask for a cd
    • or insert the cd and hold 'C' down during boot.
    • PLEASE NOTE: to get back to booting from the HD you have to hold down the 'option' button, aka 'alt' key
    • To eject the CD during boot: hold down the eject button, triangle with a line under it. Top right on some mac keyboards.
  4. net-setup eth1
    • My system wont autoconfigure the network.
    • eth1 is the wired net,eth0 is the wireless.
  5. fdisk /dev/sda
  6. t (change type)
  7. 3 (partition 3)
  8. 83 (linux)
  9. w
    • there will be no swap partition, I couldn't get bootcamp to see the partiontions when I had created 4 partitions.
  10. Follow the gentoo handbook.
    • mke2fs -j /dev/sda3
Disk /dev/sda: 60.0 GB, 60011642880 bytes

Builtin IR Remote

I am using lirc-0.8.3_pre1 with USE="X kernel_linux lirc_devices_macmini" and my Mac Mini runs 2.6.24-gentoo-r2-mactel. I created a hiddev-node with

mknod /dev/usb/hiddev0 c 180 96

and configured my /etc/conf.d/lircd in this way:

File: /etc/conf.d/lircd
LIRCD_OPTS="-H macmini -o /dev/lircd -d /dev/usb/hiddev0"

My lircd-config-file contains the following

File: /etc/lircd.conf
begin remote

  name  macmini
  bits            8
  eps            30
  aeps          100

  one             0     0
  zero            0     0
  pre_data_bits   24
  pre_data       0x87EE0A
  gap          211988
  toggle_bit_mask 0x0

      begin codes
          play                     0x04
          up                       0x0B
          down                     0x0D
          left                     0x08
          right                    0x07
          menu                     0x02
      end codes

end remote

Now just do a

/etc/init.d/lircd start

and you should be good to go. You can test your configuration with

irw /dev/lircd

Lirc needs to run, otherwise you will get a "connect: Connection refused"

If this does not work: Check that you have


in your kernel. I am not sure if you need all of them, but I have them built in.

Just a node at the end: You do NOT need to load any lirc-module! I read a few times that you need to modprobe the lircd-modules. But I think this is obsolete.

Wired Network

Works out of the box with the sky2-driver. You need


in your kernel. The driver was very buggy in older kernel version. But with recent ones it runs without any problems. At the time of writing is the latest.

Telling bootcamp to boot Gentoo

  1. reboot
  2. eject the cd
    • Hold the eject button on the keyboard,
  3. reboot
  4. hold 'alt/option' key during reboot
  5. Select the harddisk as boot media,
    • it should boot into Mac OS X
  6. In OS X, select System preference
  7. Select start disk
  8. Select your Gentoo partion
  9. reboot


Trouble shooting

eject not found

eject not found
emerge --pretend --verbose eject

lirc - OPEN

when starting e.g. irw it dies /var/log/message says: unable ot access /dev/lirc/0
working the issue
  • Attaching the streamzap, it works fine, emerging the streamzap actualy produces a loadable module, I wonder why the minimac doesn't do that.

My bultin remote works, I have posted a guide in the Configuration-Section on this article. Hope it helps. If it does, please remove this.

wont play cd's

No stream found to handle url cdda://
add the use flag 'cdparanoia'

Tried and failed

  1. fdisk /dev/sda
    • please notice the odd jump from sda2 end to sda3. Don't know why, but not planning on mucking around with it.
    • For some reason there is no /dev/sda4 in the /dev dir, I hope it's there at next boot, so the installation will be without a swap.

It seems like creating additional partitions gets bootcamp confused. Insert non-formatted text here


grub-install --no-floppy --recheck /dev/sda3
Probing devices to guess BIOS drives. This may take a long time.
The file /boot/grub/stage1 not read correctly.
grub-install --no-floppy --root-directory=/boot /dev/sda3
The file /boot/boot/grub/stage1 not read correctly.

Same as:

grub> root (hd0,2)
 Filesystem type unknown, partition type 0x83

grub> root (hd0,
 Possible partitions are:
   Partition num: 0,  Filesystem type unknown, partition type 0xee
   Partition num: 1,  Filesystem type unknown, partition type 0xaf
   Partition num: 2,  Filesystem type unknown, partition type 0x83
   Partition num: 3,  Filesystem type unknown, partition type 0x82

This problems can be solved if you make the partitions with boot camp (one macOsX and one for guinDos) If you only use rEfit to allocate free space and then you make the partitions with fdisk (in gentoo) you will never be able to install the mbr on partition /dev/sda3. I know cos I used a hole day to figure this out. So the steps are.

-Update Mac Os X 10.4 -> 10.5 (here you have boot camp) -Make two partitions with boot camp: one for mac os x and one for windows. -Download and burn rEfit, install it on mac os x partitions (HFS+)

Follow the rest of the guide. Very cool guide.

Headless Operation

The machine will not boot without a monitor attached. Connecting pins 2 and 7 of the analog VGA connector with a 75 ohm resistor fixes this. A 47 to 100 ohm resistor would probably work as well. A paperclip may work but its use could cause damage to the video adapter.
