  The 780G chipset does not have any hardware raid capabilities.
Similar to almost all other chipsets with onboard raid they are what
are known as 'fakeraid'.  It is essentially a software raid, using the
main CPU to do the grunt work.  There is a way to get this type of
raid working using dmraid in linux but there are few, if any, benefits
over linux software raid (and some drawbacks) especially if it is not
a dual boot box.
  With the buzz-words 'fakeraid' and 'dmraid' you should be able to
find more information easily enough.  Otherwise, post back with more
