While in DOS level all drives are visible/accesable why Windows cannot
use RAID disks and asks for necessary drivers? Especially during
Windows installation.


If I format a RAID partition as FAT I may install DOS : ) What's wrong with
Win?

The RAID chipset (and the BIOS firmware that supports is) offers one of
the four operation modes.

1 - RAID
1a - AHCI (for SATA) - http://en.wikipedia.org/wiki/Ahci
2 - ATA / Native IDE / Legacy IDE / Compatibility
3 - Automatic (RAID/AHCI or ATA?)

The first modes 1/1a utilizes the RAID chipset and its performance and
security features, but needs windows drivers.

The others will work OK without drivers or the above benefits by
emulating the command interface of ATA.

I wonder why Windows cannot use generic RAID driver if it's necessary
like video card. Then it may update the specific driver. Imagine that a mouse
recognized in DOS but not in Windows. Isn't it silly?

Because you need a Newer operating system if you want RAID support out
of the box.

It does ask for drivers during installation (Press F6 if you need to install
a third party SCSI or RAID driver):
http://pcsupport.about.com/od/operatingsystems/ss/installxpnew1_3.htm

What's wrong with watching and following directions when you install? :-)

I have not - as of yet - had any major issues installing Windows (2000, XP,
Vista, 7, 2003, 2008, etc) on various RAID setups. I wouldn't expect (or
want) some generic driver that *might* work with somehting as complicated as
the Windows operating system anyway - I would prefer (in all cases) to have
the latest and best driver the actual manufacturer (*and supporter) of the
product in question had.
