A friend has a asus a7pro and it will not reconise a yamaha 16x burner when it`s hooked up.It has a 52x cd rom and a toshiba dvd in it,and when the yamaha is hooked up,sometimes it will show up in the bios but never in windows ME.Changed the ide cables,changed the jumpers from master to slave to CL to takeing it off.When it`s hooked up ,the drive it`s hooked up with will not show up in windows either.It runs perfect in my machine.Any ideas?
