€X-rays are emitted in region at the inner edge of the disk, called the boundary layer
€Can be explored through eclipse studies in the X-rays and UV/optical
€Non-magnetic CVs are relatively faint in X-rays so only recently have observations achieved sufficient count rates to resolve the emission region
€Eclipses are sharp, indicating that the emission is from a region only the width of the white dwarf, and not extended into the disk
€Some indication that emission is from the polar regions: weak magnetic fields or obscuration
