Hi Kaushal,
Maybe there's some kind of misunderstanding. The term software raid can be
misleading because IMHO mdraid is also an software raid. So let's use the
term fakeraid for those controllers which make one believe they do
everything in their hardware but in fact simply do some kind of software
raid in thier proprietary OS driver.
So, what you should try to find out is whether your controller is not
usable in raid mode because the OS has no support for it (seems obvious)
or if you set the controller into AHCI mode in BIOS, if the controller is
usable by the OS without any additional driver.
So, go to the BIOS and set the disk controller to AHCI mode (if such
setting exists) and try to install the OS. If you'll see any disks in this
configuration, the just go with mdraid and you're done.
