Im working on installing my Soyo Dragon K7+ mobo this evening. I have a few questions: 1) What is VIA OnChip LAN? Do I need it? 2) If I install a USB 2.0 card, does that render my other USB ports useless or will they still transfer data at the v1.1 rate? If they are useless, do I have to disable them in my BIOS? 3)If you have the same board as me, what is the Standard Infrared (SIRCON) 10 pin connector for? Thanks so much. This is my first time building by myself and I want it to go smoothly!!
