Many are, but not all.
The ones that do have an Intel IOP 8030# (i960-based) or
8032#/8033# (StrongARM/XScale-based).

The BIOS is _only_ for 16-bit Int13h (interupt 13 hexadecimal) services.
I.e., boot-time and DOS (including DOS7 aka Win9x/Me in "compatibiltiy mode").

The presence of a BIOS does _not_ mean it's "hardware" RAID.
In fact, that's how 98% of the "FRAID" cards work -- totally _useless_ once
a 32/64-bit kernel boots.
