I couldn't sleep so I had another go and found some more problems but got it installing under EFI and booting in EFI mode! eventually .... Definitely need the kernel options acpi=none nointremap nomodeset to do this again need to use tab and add these options in manually when booting via EFI off external CD Note: USB made from CD image (by dd to USB device) doesn't work at all on MAC pro Need proprietary firmware but the loader is broken. I got the firmware and tried placing it in several places and it couldn't find it. This included USB top level, in subdirectory b43 on USB, in root file system / and /b43. In the end I looked at the script running and noticed the /lib/firmware directory didn't exist so I just created the /lib/firmware/b43 directory and placed required firmware files directly in that and it was able to move on and detect the access points and authenticate with WPA2 ! I attach them - it might not need ht0initvals29.fw - as I might have copied that over by mistake but it certainly wanted the other two: ucode29_mimo.fw ht0bsinitvals29.fw Other issues minor - but annoying o After setting up grub it doesn't copy over the extra options I typed in (mentioned above) that allow the kernel to boot. So by default it will lock up! o When the extra boot options are present still has the annoying kernel bug where it prints repeatedly: applesmc: read arg fail over and over for about 30+ secs before it times out and continues on. This is fixed in later kernels such as 3.6.0 which I am running happily. Back port fix? Doesn't offer discard as an ext4 mount option - yet this is recommended for flash drives like the MAC Pro has. Could offer tmpfs to allow /tmp to be a tmpfs filesystem? I did a non desktop install and tried get wmii and X working manually but can't get X to start to start up otherwise ok. It discovered my other partitions and correctly listed all my kernels yeah! Graphics look *REALLY* good under the EFI boot. Thanks Andrew
