You don't need to install a BIOS that comes on the MOBO, all you have to do is hook all the components together. If you order your MOBO/Proc from www.mwave.com
they test your MOBO and Proc as well as assembling the proc/heatsink/mobo together, which is the 'hardest part' because you could damage the CPU(proc). Once you receive that all you need is some screws and a case, the rest is plug and play pretty much! If you have any 'in-depth' question just ask, someone around here knows for sure. Google has tons of guides on assembling a PC, it is super simple and kinda cool to know you 'built' it yourself.
