'Male bovine excrement' applies.
I used 'hardware RAID' because that is -precisely- how the OP described
their equipment. And Dell does offer at least one such controller.
That aside, my statement is entirely accurate, _as_written_, regardless of
the hardwaare that the OP has.
Now, I'll grant it is possible that you know more about the OP's equipment
than I do, but _I_ will assume that the OP knows what they are talking
bout, with regard to -their- hardware configuration.
Further, I, personally, have a fairly similar Compaq machine, which has
hardware RAID, with it's own BIOS (including configuration/setup screens).
Oh, yes, FreeBSD _does_ recognize the raid volumes -- with NO RAID support
whatsoever in the O/S itself. I run full-custom kernels with no loadable
modules, I _know_ what capbilites are/aren't present.
