Read the reviews for devices like that on Newegg, before you buy.
Some of the early ones, used to freeze or reset themselves
after about ten minutes of usage. Make sure the reviews are now
positive, about the operation of those things, before you buy one.
If they're still freezing or glitching, then stay away.
Plug your keyboard, into the Gigabyte keyboard port, and the
mouse, into your $8.99 adapter. That way, the BIOS setup screens
are more likely to work.

Some computers which have a single 6 pin mini-DIN, actual place both
mouse and keyboard signals on the same connector. There is no evidence
in the case of your Gigabyte motherboard, that they are doing that,
so this is unlikely to be available on your new motherboard.
On some notebooks, you can use an adapter like this, to get both
connectors. But for this to work, the original connector on the
laptop, would have to have
power, ground, data, clock, data, clock (PS/2 mini-DIN kbd+mouse)
or in other words, all six pins in use. Normally, two pins on the PS/2
six pin mini-DIN are not used. I have no first hand experience with
these, or the concept, so I cannot tell you how common this is as a
solution. A solution like this, provided on a notebook, would save
precious I/O space along the edge of the case.

How that cable works, is described in this article.
http://www.burtonsys.com/PS2_keyboar...r_pinouts.html
"The "Y-splitter" cable adapter is connected as follows:
Keyboard (F) Computer (M) Mouse (F)
------------ ------------ ------------
pin function pin function pin function
1=data ---------- 1=data +--- 1=data
2 n.c. 2 -----------+ 2 n.c.
3=gnd ----------- 3=gnd ----------- 3=gnd
4=+5v ----------- 4=+5v ----------- 4=+5v
5=clock --------- 5=clock +------ 5=clock
6 n.c. 6 --------+ 6 n.c. "
The power and ground feed both cables. There are enough pins,
so both the mouse and the keyboard, get their own private
clock and data signals.
