> Does Dell create the BIOS, or does it come from the motherboard
That depends upon the vintage of the Dell system you are talking
about. With the early Dell systems, Dell branched off from an old
PhoenixBIOS (1988!) release and modified it to be what they wanted it
to be, updating it for new systems along the way. This BIOS has a few
different faces--you've seen it in the systems where the majority of
the setup utility text is in blue (black background), in the
"predominantly grey" setup utility and the "blue background/green
foreground" setup utility. This is probably the closest thing there is
to a "written by Dell" BIOS as they have had to take that old Phoenix
code base and update it as new CPUs, hardware, storage devices, or
whatever came along.
Systems using this BIOS include the LatD800, OptiPlex GX520/620,
OptiPlex GX400, Dimension 2400, 45/46/4700, 81/82/83/8400 and others.
Sometimes, especially with newer systems, Dell just customized an
existing BIOS, like they did whenever they put a designed-by-Intel
motherboard in a system. In this case, the motherboard and the setup
utility both look a lot like the original product upon which they are
based, with some options removed. Someone else did the heavy lifting
here. Systems using this sort of BIOS would include the whole of the
Dimension L5xx/2100 series.
Today's Dell systems, having very generic motherboards, usually have
no Dell influence on the BIOS other than in the setup utility (where a
great simplification takes place) and in the startup logo. Any of the
Inspiron desktops use this BIOS.
The laptops won't have as generic of a motherboard, but I suspect that
considering how Dell has now totally farmed out the low end/home end
desktops, that the contract assembler does most of the BIOS creation
work and slaps a Dell logo on it.

In general, there isn't a reason to upgrade a BIOS unless there is
something in an update that is needed.
While the update process is extremely bullet proof, there is always the
chance of a problem. Most likely is loss of power (or turning the
computer off) during the update. This can leave you with a door stop.
When it comes to BIOS updates, the rule "If it ain't broke, don't fix
it!" definitely applies.

Another week, another BIOS update.....
It'a version A08 and called "recommended".
