adaptec hardware raid 1 29320a hostraid

[Michael Hanulec]

It depends upon your description of 'everything'.  It does have the 
necessary RAID drivers for most cards.. but unless there is a fully 
functioning replacement for HostRAID in 2.6 then I would say no.  I 
haven't look to see if this was the case though.
