I've tried some Linux installation procedures today which were not
really successful. But this report may help you.
Hardware: Mac Mini (Intel Core Duo)
Prerequisite: Installed firmware upgrade with CSM support
1st try: Clean HD principle
Having booted Ubuntu Breezy Install CD I needed to load the ahcpi module
and define the addres of the SATA controller (many thanks to Matthew!).
Parted (unpatched) showed one GPT partition. Fdisk showed all slices as
partitions. I cleaned all paritions (incl. EFI partition) and set up an
'usual' Linux partitioning. Grub didn't install at all, without a clear
error message, LiLo (not eLiLo!) had been installed at the MBR of the
disc. System didn't boot, only the question mark icon blinked. I thought
the CSM would also detect BIOS boot loader in MBR, but I was wrong.
2nd try: Boot Camp
I installed boot camp beta and let boot camp partition the hard
drive. I said boot camp to install Windows, but inserted the known
Ubundu Install CD. Boot camp got the mac to restart. CD booted, I had to
load ahcpi manually and set up the system into the partitioned space by
boot camp. Again, grub-install only gave errors, LiLo could have been
installed into MBR of the disc, but not into the MBR of the linux
partition. After reboot the system booted Linux directly! Unfortunatly
the SATA controller was not detected, so ony emergency shell is
available. Booting with pressed Alt key only shows the OS X partition,
OS X is booting sucessfully if selected.
So there might be a way to configure EFI to regard any bootloader at the
MBR of the disc. This is probably what boot camp does in order to boot
Windows. Actually my Mini boots from MBR, so tomorrow will I try to
install Linux on the whole disc.
: Setting up a Windows XP partition with boot camp does something
interesting. It creates a second GPT partition _with_ another 200MB vfat
partition ahead of the Windows partition. Can someone acknoledge that?
What's the purpose of this partition anyway?
So far from today, comments are welcome (Mail or IRC).
Cheers and thanks to all for your work!
