a. The "system board" referenced...is the motherboard, which is made by Asustek.
b. The product name data reflected there is...unreliable and does not reflect a given Asus motherboard model.
If you really want to know the motherboard model, you can open the case and take a look...or try Start/Run...type msinfo32 and then look at the data reflected for System Manufacturer/Model. If you have a Gateway, Dell, etc. system, you will not see motherboard data but system data there.
There is a program, [post="http://www.gtopala.com/"]System
Info for Windows or SIW[/post] that should reveal that data and more.
c. If you remove or disable any current functions in a system...you will not be able to use them until you reverse the process.
d. I have no idea why that hot-swappable comment is there...but I know of nothing other than hard drives which might ever be hot-swappable when connected directly to the motherboard. USB devices, yes...motherboard devices, no. Do you have an owner's manual for this motherboard or system? If so, it should contain pertinent data about board capabilities/functions.
