You probably could change that easily enough.

"BIOS RAIDs" is a rather sweet euphemism for "crippled pretense of
hardware RAID, which is in fact emulated by software". I've got no
problem with telling the users that what they have _is_ software RAID
and needs to be treated as such.
Windows doesn't use the BIOS to access the device at all; the
corresponding hardware drivers emulate that.
