The new motherboard will likely come with a CD that holds drivers for onboard video, sound and NIC, so that should be okay. Your outboard stuff like a MIDI interface will have drivers already on your hard drive if you are using it now. This should go smooth as silk for you.

Remember that the motherboard was not actually built with an operating system in mind, but I would do some research to make sure the drivers available go back to XP. Since Micro$oft disowned XP a lot of hardware companies no longer care to write drivers for it. I will also add however that I have never had an issue with OEM supplied drivers and I once, as a text, put hard drives on a new motherboard that ran XP, Vista and 7, reloaded OWM drivers each time, and they worked fine.

Typically is you buy a "name" motherboard the coverage is thorough. If you go with "Bob's Motherboard" you may have problems.

Mileage may vary.
