If you don't have motherboard with UEFI Bios, I can't help you
I played with it for about 1 hour (10 or 20 reboots to test) and finally figured it out on BIOS mother board.
The set up is very much like what your instruction says, maening install Clover's /EFI to EFI partitions of the RAID0 volumes.
Then all I need is copy "Boot" into both Boot OS X partitions. Now that I think about it, Slice has mentioned something like it before but I did not understand the boot process. Now it makes sense.
I had to switch to Clover for 1 reason even if my board is BIOS based. I have a off-brand ATI card. After every update, Chamelon refuses to boot. I would have to boot from another partition, change the device ID of the card in 2 kexts. Clover boots without a fuss, gives me unaccelerated screen to work it. This is the game changer for me.
Thank you for your response.
