ASRock Z87 Extreme4 RAID configuration

I have a terrible feeling that this is going to be a very simple answer, but I've spent a couple hours reading and troubleshooting without any success.

my setup:
ASROCK Z87 Extreme4 w/ 16gb ram & Intel 4770k
r290x

I have 4 Intel 520 240gb SSDs in one 5.25" chassis hooked up to the middle 4 sata ports on the motherboard. (ports SATA3_0, SATA3_1, SATA3_2, SATA3_3) I can see all 4 drives in the UEFI bios as separate drives, so I'm not running into something where my drives aren't being detected.. I don't think.

In looking at various screenshots and manuals of the bios, I am supposed to see an "Intel Rapid Storage Technology" option under the "Advanced" menu in UEFI. For the life of me, I can't make that stupid option appear.

The other option that is supposed to be available is using the Intel RAID Bios, which you get by pressing ctrl+I when prompted. Of course I never see that prompt, and I am spammed with "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key".

Can anyone out there enlighten me as to what I'm missing?

change SATA Mode setting from AHCI to RAID

What are you trying to do? Build a RAID 10?

Like bloodypulp said, in the BIOS, make sure the SATA mode is set to RAID. You will then be presented with the option to configure the RAID when you reboot.
