Depending on who you talk to "on-board (hardware) RAID" isn't
necessarily "proper" and some consider it "fake".  I have no idea how
this is determined.

What is a "MD device" and will this scenario allow me to a:

Configure my array as RAID0

Dual/Triple/Quad-boot with other Operating Systems (including but not 
limited to, Windows XP).

I started off trying to do the dual-boot thing, but it's a no-go.
Ubuntu (and Debian and Fedora as well) won't recognize the RAID.  It
comes up as my just having two separate drives (which I do of course,
but they should be showing up as RAID.

Depending on who I talk to I either do or do not have "fake
RAID/fakeraid".    Do SATA drives connected to a SATA RAID controller
automatically equal "fakeraid"?

I have two 250 GB SATA drives connected to a Promise FastTrack 378 RAID 
controller.  This and an onboard VIA VT6420 RAID are connected to and 
came with my ASUS A8V-Deluxe Motherboard ( VIA K8T800 chipset).

Someone recently told me I might have better luck connecting the drives 
to the VIA controller instead (it's unused).  I'm going to be trying 
that soon (well I'll be paying someone to switch it for me, actually).

Presently I've got Ubuntu occupying parts of both drives with on other 
OS installed. This is a temporary situation, just so I can have 
something going. It is by no means what I want in the long term.

My efforts to get the drives switched to the VIA controller could still 
be in vain, but we'll see.     Between this and the problems I'm having 
connecting my new printers, printers I bought based on their supposed 
excellent Linux compatibility -
