Every mobo ASUS has built in at least the last 2 years has had adjustments
within the BIOS. Why would one even think they'd come up with an odd ball
mobo that only has a fixed switch to change FSB and way in the BIOS to
change the multiplier? And where would one research something like the
options in the BIOS before purchasing when it is a brandnew product? I
don't know what ASUS was thinking when it came out with this crippled
product? And no, they don't offer a BIOS that corrects this major
shortcoming. Damn ASUS!
A few links will answer some of your pre-purchase questions:
You can find a downloadable manual on the download page. Many
manuals even have a picture of the motherboard, although not all
manuals now include that. There are pictures of the BIOS screens
and explanations of what the switches do, and so on. Also on this
page, are BIOS files, and by reading the "More" links, you'll get
an idea of how much development work has gone into the board. If
there are few releases (such as on some of the server boards),
that is a warning that if there is a problem with the design of the
BIOS, it might take a long time, if ever, to get it resolved.

This link warns you about combinations of BIOS and processor
that are not expected to work. Just by the structure of some of
these pages, you'll get the idea that new processors need new
BIOS for support. Some product families are worse than others in
that respect. If you deal with a local retailer, they'll open the
box for you, and verify the BIOS release (mine did).

I think there might even be a pre-sales phone number for you
to call.
As for microATX boards, they aren't intended for enthusiasts.
They are intended for system builders, building cheap boxes for
corporate users. After all, why have those terrible built-in
graphics, if you are a gamer ? Some of the microATX boards don't
even support PC3200 memory. I would recommend a full sized
board, to get a feature set you can use.
Buying motherboards based on price is a mistake. If you want
the lowest price, you've got to ask a lot more questions,
like what features got cut, to make the price so good.
Say you now switch from Asus to say Pcchips or ECS.
You'd want to do a lot more Googling, to find out if the
problems with a board, are problems you can live with.
The A7V400-MX also has the switches, and using the switches
means saving on the chip that drives the multiplier and frequency
setting. They probably saved a whole $1 by doing that.
The PC industry is full of cost cutting, functionality busting
choices. As a builder, your "value add", is knowing about
those choices.
