How to install CentOS 6.4 on Mac Mini?

I have bought a new Mac Mini, and would like to use it as a Linux server. Now I'm trying to install CentOS on it. I downloaded CentOS-6.4-x86_64-netinstall.iso and booted the Mac Mini from a USB-stick. But during the installation process I get these errors: dmar: No ASTR found IOAPIC id 0 under DRHD base 0xfed9100 HPET id 0 under DRHD base 0xfed91000 Enabled IRQ remapping in x2apic mode Enabling x2apic Enabled x2apic Setting APIC routing to cluster x2apic Kernel panic - not syncing: No mapping iommu for ioapic 2 Pid: 1, comm: swapper Not tainted 2.6.32-358.el6.x86_64 #1 Call Trace: ... Any suggestions what the problem is? Do I need a different binary to be able to run on an Mac? According to a tweet, CentOS 6.4 seem to work, at least on older, Mac Mini's: https://twitter.com/courtneycotton/statuses/312267424605036544 -------- **UPDATE**: the suggestion of adding noapic to the boot took me further in the installation process. Now I had to select an installation medium. The choice is CD/DVD, Hard drive, NFS directory or URL, and I have a *USB-stick*, so I choose *Hard drive*. Then I'm supposed to choose a partition that holds the installation image for CentOS, the choice is between /dev/sda1, /dev/sda2, /dev/sda3 or /dev/sdb1. Here I have really no idea what name my *USB-stick* has. I have tried with them all, but if I choose e.g. /dev/sdb1 I later get the message: > The installation source given by device ['/dev/sdb1'] could not be found. Please check your parameters and try again. I put my iso file on the USB-stick by following the Ubuntu instructions . Any suggestion on how to go further in the installation process?
