Should the BIOS be setup for RAID or AHCI? I have it set to RAID, of course. But the driver installer mentions ACHI Compatible.
I was able to get the array detected in Windows and I created a disk. I did this by loading the floppy/F6 driver manually (within Windows, not during installation). But I obviously want RAIDXpert2 up and running so I can see the array's status.
Edit:
I uninstalled all the AMD drivers/software, then tried installing again, but noticed that amd_raid_drivers_9.2.0.105.exe wasn't really doing much when I told it to install both the driver and RAIDXpert2. It finished very quickly and RAIDXpert2 didn't get installed. I ended up running it once with just RAIDXpert2 selected (since I though I already had a working driver), and RAIDXpert2 reinstalled. I then ran it again with only the driver selected (since RAIDXpert2 still wasn't working, I figured the Floppy/F6 driver wasn't enough), and this time it actually installed a driver. After a restart, RAIDXpert2 worked finally. I can now see that my array is initializing (or "CREATE"ing).
