Installing onto RAID 1

I am trying to install 10.9 onto a RAID-1. I have created a bootable thumbdrive that has worked for several installs already. I boot from this, open Disk Utility, create the array and then go back and install onto the array. Everything goes smoothly until I reboot. I cannot get a bootloader (latest Chameleon and some older 2.2s or Ch**era) to recognize the volume.

 

Has anyone been able to do this? I have followed multiple posts to write MBRs, etc. to both drives with no luck.

 

Thanks!

Solved:

 

Get a Terminal in either the installer or regular boot, doesn't matter.  Just make sure, with "diskutil list" that disk0 and disk1 are the elements of the RAID 1 array.
 

# newfs_hfs -v EFI /dev/disk0s1
# newfs_hfs -v EFI /dev/disk1s1
# mkdir /Volumes/EFI
# mkdir /Volumes/EFI2
# mount_hfs /dev/disk0s1 /Volumes/EFI
# mount_hfs /dev/disk1s1 /Volumes/EFI2
# cd /Volumes/USB/usr/standalone/i386
# fdisk -f boot0 -u -y /dev/rdisk0
# fdisk -f boot0 -u -y /dev/rdisk1
# dd if=boot1h of=/dev/rdisk0s1
# dd if=boot1h of=/dev/rdisk1s1
# cp boot /Volumes/EFI/
# cp boot /Volumes/EFI2/
# umount /Volumes/EFI/
# umount /Volumes/EFI2/
# fdisk -e /dev/rdisk0 <<EOF
