Apple Mac Mini
How-to
Configure yaboot
Yaboot is yet-another bootloader for computers that use Open Firmware. Yaboot is to PowerPC-based computers what either LILO or GRUB is to x86-based computers. Yaboot will already have been installed on your computer by the Debian installation process. Yaboot's configuration file is /etc/yaboot.conf. The only thing I had to add was information about the video card. A Mini running Linux works fine when connected to a VGA display via the supplied DVI-to-VGA adapter. To get video to work when connected to a DVI display, however, it's apparently necessary to specify the video parameter to the Linux kernel. The Mini uses an ATI Radeon 9200 video card. To specify this, add a line of the form:
append="video=radeon:XresolutionxYresolution@60"
My entire yaboot.conf file is below.
Most of the lines you shouldn't change
unless you really know what you're doing
since a mistake can make Linux unbootable.
The bold lines are the only ones I added/changed.
You can consult yaboot.conf(5) for the details about the other options.
boot=/dev/hda2
device=/pci@f4000000/ata-6@d/disk@0:
partition=5
root=/dev/hda5
timeout=100
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
enablecdboot
macosx=/dev/hda4
image=/boot/vmlinux
label=Linux
alias=l
read-only
single-key
append="video=radeon:1600x1024@60"
Once you've finished editing,
you need to run ybin to install the new configuration file.
