Ok. My new Dragon Plus mobo should be here tomorrow, along with the rest of my components. This is my first computer that I will build and I had a question. When updating the bios, it says "1. Prepare an empty bootable disk. In order to do this, format a disk using the format a: /s command (use b: or other drive letter if appropriate). Make sure that there is nothing on the disk except for boot files. How and where do I do this? and do I need to do this before I turn the pc on for the first time?
