I'll try and keep my English as standard as possible
RevoDrives are a bit of a system hog and can make funny changes even between boots when being configured with new gear being installed for the first time and a few boots after.
when installing mine i came to know a few things it liked to do ......like for no apparent reason it would change the boot sequence with no help from me.....so all of a sudden it would hang on boot often......instead of hitting BIOS reset......reboot and hit the delete key and check what you are booting off constantly
Another thing I learn't about them is they don't like everything connected up in one hit and then you try and configure them
I would strip the system down to :
RevoDrive (in the bottom 8x slot, this slot has been proven to give the least issues)
1 stick of memory
GPU (and no sound card) set display in BIOS to PCI-E-1
Now you have a good chance to install under ACHI or you could try the reg hack to load ACHI first under the present install..... there's several ways to do this ....if you need links just ask!
If you get this far... now load the first raid set, not both (all 4 drives)....start with say your 2 disc set for raid0 and have another go at getting them installed and configured, ....remember to constantly check what your booting off every time you visit BIOS.....you will catch it playing naughty at some time........unfortunately this is what you will have to do during the entire install of all your bits and pieces.
You said you are trying to installing a 2 disc raid1......... and a 2 disc raid0........Why are you doing this ?
