I suggest attempting to reset the cmos on the motherboard via a jumper labeled pwr cmos, power jumper or just plainly, a big shiny flat yet round coin style battery. There are lots of tutorials on that topic with more info than I care to share here. Good luck!
Nice to see some double bass enthusiasts on here! I am in the process of building an electronic midi drumset from piezos, some old stationary cardio equipment and an alesis dm5. The tooling, oh the tooling. Taps and dies, welding, now i need a lathe to make a double bass pedal from scratch... Www.gpsn.uspto.gov is a great resource for technical info and also creepy government technology. Ill post when i can. Peace
