Sure you can... this is the internet... heck, you can blame Obama and
Democrats for this failure... and show ties to Hitler and Aliens too
;-)

Well, never hurts to try... be sure to forward whatever reply you get
from that :-D

I think you're confusing two different things... HostRAID is an
Adaptec creature... think neutered RAID chipset soldered to the
motherboard, very similar to what happens to video cards on laptops,
or maybe even more apropos the difference between hardware modems and
software modems.
All HostRAID is onboard RAID, but not all onboard RAID is HostRAID.
There are other chipsets out there (I mentioned LSI for one) and some
of those DO work... I think a lot of it depends on the implementation.
Now, Keep in mind, I'm not a hardware engineer or anything, and this
is just personal experience on IBM hardware...
But Adaptec's HostRAID onboard RAID is very dependent on the driver to
provide various RAID levels whereas LSI's onboard chipset will work
using the regular LSI drivers, IIRC... The caveat though, is that
with most, if not all, onboard RAID devices, you get a subset of
functions, mostly you get RAID-0 and RAID-1 only... MAYBE you'll get
RAID-10, and MAYBE RAID-5 for the higher end devices...
But either way, HostRAID is a brand, not a category...
In any case, the stuff I found on google was a pretty generic search...
But the Syba cards listed use a Silicon Image chipset... and that is
supposed to be supported natively in the kernel since 2.6.25.
And looking more closely, I am partially mistaken, but too lazy to
retype all this ;-)
HostRAID == Adaptec onboard neutered raid chipset
Host RAID == generic term for onboard RAID using internel drives as
opposed to an external enclosure, apparently.
Sigh... I HATE it when that stuff happens...
Time to go home and give my wife her birthday surprise...
Cheers,
Jeff
