1 CPU: AMD FX-8150 Zambezi 3.6Ghz Socket AM3+ 125W 8-core RAM: CORSAIR Vengeance LP 16Gb (4x4Gb) 240-Pin DDR3 SDRAM 1866 CML16GX3M4A1866C9B Mobo: ASUS M5A97 LE R2.0 AMD 970 PSU: Thermaltake TR2 TR-5000 500W ATX12V v2.3 GPU: ASUS 210-SL-512MD3-L GeForce 210 512MB(TC 1GB DDR3) 32-bit DDR3 PCI Express 2.0x16 SATA: 2 x Seagate Barracuda ST31000524AS 1TB 7200 RPM 32MB SATA 6.0Gb/s 3.5" Internal Hard Drivw

I have assembled this system myself for my webserver. However, I am experiencing problems with RAID array configurations in UEFI BIOS. Fedora 18 has a known bug, hence I switched to Ubuntu server 13.04 (64-bit). However, even Ubuntu fails to install. Here's what I did:

Configure SATA ports 1-4 as RAID (both hard drives are in those ports) Configure SATA ports 5-6 as IDE (SATA DVD Drive) RAID ROM Controller as Legacy Rom (UEFI option seems bugged or I have no clue how to configure it, even though I select Storage boot option as UEFI driver first)

Reboot the sytem

Configure RAID in legacy interface (CTRL + F) and set up RAID 1 array with Initialization: Full, and the rest are default settings (Read Ahead, etc)

Then I put Ubuntu Server ISO and do the installation with RAID settings that Ubuntu detects...

When installer finishes - nothing is hapenning, except UEFI sees Ubuntu with UEFI label on it, but after the POST it says that no bootable disk is found and etc.

I have tested RAM with Memtest86+ and it passed. I have installed Windows 7 on both Hard drives just to check if hard drive is bad, turns out - not. PSU was tested with my Coolmax PSU tester. Hence, hardware is not at fault, except that UEFI (my suspicion). However, I have upgraded it to the latest version 1709 (http://ca.asus.com/en/Motherboards/AMD_AM3Plus/M5A97_LE_R20/#download) UEFI is by American Megatrends, Inc version 2.10 - but no help at ami.com

I am lost here...

Why UEFI driver for RAID does not work on the mobo? Why Ubuntu Server reports that it is installed in UEFI, but I cannot load into it after POST?

Any help? Has anyone actually set up a RAID1 array with UEFI driver? And what linux distro worked?

I cannot believe that Windows 7 has no problems flying on this hardware...
