Specifically as a workaround for this broken firmware, there is now a new flavour of i386 netinst image. Unfortunately, all of the normal Debian installer options for both i386 and amd64 now include 2 El Torito boot records (one for BIOS boot, and one for EFI boot). It tried to offer a choice of the boot options, but it locks up instead. When booting off CD/DVD, if there is more than one El Torito boot record on the disc then the firmware gets confused. The oldest Mini (macmini1,1) is typically the most problematic, due to bugs in its firmware. The best way to start the Debian installer varies a lot, depending on the age of your hardware. See below for more detailed instructions. Mac OS X) then you'll be more at the mercy of the other operating systems. However, if you do want to dual- or triple-boot with other OSes (e.g. Recent versions of Debian (at least from 8/Jessie onwards) should install and work reasonably well on most Mac Minis without needing any other software to help with setup, assuming that you only want to be able to boot Debian. It's also possible to boot wheezy installers from a USB key in this manner. You must use OS X's 'bless' utility to change NVRAM entries allowing this to boot. This gives the option of installing rEFIt (or other EFI bootloaders?) on a USB key. To enter the builtin boot menu, hold the 'Option' key while booting. In consideration of all of the above, updating the computer's firmware is the simplest way to easily install and boot Linux and also get 2D/3D graphics acceleration. Booting in the BIOS compatibility mode also means using either the LILO or GRUB bootloaders, and having an MBR partition table (either hybrid GPT/MBR or plain MBR). Without it, you only get unaccelerated frame buffer graphics. This is because the X.org / XFree86 drivers for Intel and ATI, as well as the Linux text console, rely on the Video BIOS and Apple's firmware only provides a Video BIOS when booting in BIOS compatibility mode. In addition, if you want good graphics support in Linux, you must boot it using the BIOS compatibility mode. Recent firmware adds a BIOS compatibility mode, including detection of BIOS-bootable disks and CDs in the built-in boot volume chooser. This is important - some older versions of firmware won't provide some of the underlying support that you'll likely need to install Debian. Verify that your computer has the latest firmware. macmini2,1 installation specials and pain.
