Z68MA-ED55 + UEFI + Windows 7 64-bit Installation

Question

I've been trying for a few days now to figure out how to install Windows 7 64-bit on a single, fatty 5.5TB GPT partition in UEFI mode for this motherboard while utilizing RAID5 and Intel SRT caching. Here's the scenario:
1. I have (3) 3TB hard drives that are configured in a RAID5 array giving me approx. 5.5TB's of usable storage.
2. I have (1) 64GB SSD that I want to use for Intel SRT caching for the above mentioned RAID array.
3. I want a single, big fat 5.5TB GPT partition for the above mentioned RAID arrary.
4. I want to install and boot Windows 7 from the above mentioned 5.5TB GPT partition.
The reason for all of this is that Windows 7 64-bit cannot utilize any disk space beyond 2TB on the disk it's installed on.... unless it uses GPT... and you can only boot GPT using UEFI... This motherboard supports UEFI, but provides no details that I can find on how to install Windows 7. I can get into the EFI shell, and dink around, but I cannot browse any mounted drives (example, using simple "ls" command from any drive/path I get the error "ls/dir: cannot open current directory - Not Found Exist status code: Not Found"
I'm decently familiar/comfortable with Linux/DOS/CLI work, but I'm not having any luck browsing any file system I try to mount through the EFI shell.
I know what I'm doing on the RAID side, I can get RAID/SRT/Windows 7 64-bit working with MBR-type partitions and normal BIOS start up. Again, the problem is that that there's no way to access/partition the space after 2TB on the fatty 5.5TB RAID array drive that Windows 7 is installed on.
SO! Any geniuses out there?

Answer 1

I figured out how to do the GPT part of things with my Z68A-GD80 board, but only in AHCI mode (still pondering RAID mode for SRT caching) I'm hoping it is similar for you:
Make UEFI the first boot device in the main boot order menu.
After the Windows boot DVD is inserted (may need to restart into the BIOS) an EFI boot option will appear under the UEFI boot BBS Priorities submenu. Select it as the first boot device.
Install Windows 64 bit with GPT partitions to 3TB drive.
After it reboots, go back to the UEFI boot BBS Priorities submenu and make EFI Windows Boot Manager the first boot device.
Boot into Windows.
I may give up on the GPT partitions if I cannot get it to work in RAID mode; Seagate's DiscWizard utility magically allows the remaining space to be formatted as a separate partition for it's drives when they are already formatted as MBR. (But it only works with Seagate drives unless its installer is hacked.) If you ever figure out how to get RAID mode to work with one big GPT partition let me know!
