Asus Sabertooth 990FX RAID - Drives disappear

[snapuswipe]

I just bought an ASUS Sabertooth 990FX yesterday afternoon and two Samsung 830 256GB SSD's to RAID with the board. I've got them plugged into SATA3 ports one and two and, if SATA1-5 is configured as AHCI, the two drives show up. However, if I set them to RAID (both Legacy and UEFI drivers) the drives disappear from the BIOS (under Advanced->SATA, but not under Boot) and when I reboot, the UEFI BIOS pops up. If I configure the ports as AHCI, I at least get the boot media error message as the hard drives have no boot record. No matter what the configuration, Ctrl+F does nothing whether I press it repeatedly or hold it through the entire boot.

What's going on here? I hope I'm missing something obvious.

Snapuswipe - Did you ever get this issue resolved? Just got a 990fx 2.0 and am experiencing the same issue. I'd like to setup two Seagate 1TB drives in a RAID 1 config and same thing: Detected under AHCI but as soon as the SATA ports are config'd to RAID, they aren't detected. I don't have CTRL+F as an option during POST.

Going round in circles and am not seeing the solution.

Am I expecting too much? Used to server class RAID hardware config's, so do desktop RAID controllers not operate similarly? In the sense that the hardware presents a logical drive to the OS, abstracted from the physical?

Should just work, so what am I missing?

Thanks.

Guess I had to sleep on it. Decided first thing this morning to clear CMOS/RTC, in case the board was stuck on 'stupid.'

Reset, restarted, went into BIOS and setup the relevant ports as RAID. La voila, CTRL+F was available, and RAID set configurable.

Good work, I went looking on the Asus web site however there isnt much info on the board period...
