Dual Booting Mac OS X and Arch, rEFInd fails to open initrd file

Question

I gave up on trying to solo boot Arch on a MacBook(1,1), and I'm dual booting. I have Arch installed on its own partition, and rEFInd is installed and configured through Mac OS X. I followed the wiki's instructions on moving the initramfs files and creating refind_linux.conf in Arch's folder on the EFI partition, and when I reboot, Arch appears as a boot option! This is good news! However, when I select it, the following happens:
rEFInd - Booting OS
Starting vmlinuz-arch.efi
Using load options 'root=/dev/sda4 ro rootfstype=ext4 systemd.unit=multi-user.target initrd=\EFI\arch\initramfs-arch.img'
Failed to open initrd file: EFI\arch\initramfs-img
My question is, do I need to install refind-efi on the Arch partition, even though I've installed rEFInd on Mac OS X?
Also, do I need to install GRUB in Arch, even though I've [attempted to] used EFISTUB to link rEFInd with Arch?
Thanks in advance for your help.

Answer 1

I got 32-bit UEFI to work on my macbook, and I found it to be rather straight forward.  But 32-bit UEFI is not incredibly common, and I wanted to have a 64-bit system so that I could potentially chroot into my other computer's disk if necessary.  So that is why I ended up using bios compatibility on my macbook.
Edit: Oh yeah, and yes, using MBR only is also another way in which you can use bios compatibility mode.  Basically you just need to have a MBR with more than one protective partition, and I think you need to have one partition marked as bootable in the MBR.  It has been a while since I got all that macbook stuff working though, so the info is a bit stale in my head.
