New machine:
motherboard ASUS A88MX-A
APU: A8-7800
HD - 2 Mushkin 250GB SSD
BIOS date is 4/25/2015
With the BIOS set to IDE drives the install is flawless.
I erased the HD. Set the BIOS to RAID. Set the RAID controller to RAID1.
The install now gives an option of where to boot, from MBR or /. By default MBR is disabled and ‘/’ is enabled. Completing the install, no boot.
I switched the options to enable MBR and disable /. Still no boot. I tried again enabling both, still no boot.
I can use the machine as an IDE. However, I want that extra comfort that comes from having the HDs mirrored.
My idea would be that you first switch on the “hardware” RAID and then install openSUSE (which will be unaware of the fact that it is a hardware RAID and uses disk ids from the disk where you installed on). But when I read you post it looks as if you first installed and then changed the “hardware” underneath what you have installed.
Also you may do better with software RAID rather then the FAKE RAID (BIOS assisted) from a MB… Don’t believe you get a full RAID experience from a $0.50 chip on a mother board.
When I initially when to install, I didn’t understand how to set up the RAID. I was anxious to see if the machine worked (home built project). After it installed, I figured out how to create the RAID. I wiped the hard drives with a bootable program from a USB drive. I created the RAID and tried the install.
