3. HARDWARE SETUP 3.7.4 Audio Modem Riser (AMR) Slot This connector supports a specially designed audio and/or modem card called an AMR. Main processing is done through software and controlled by the motherboard’s sys- tem chipset. This provides an upgradeable audio and/or modem solution at an incred- ibly low cost. There are two types of AMR, one defined as primary and another de- fined as secondary. This motherboard uses the primary channel so that a secondary AMR can coexist without the need to disable the onboard CODEC. The motherboard’s onboard CODEC (optional) must be disabled when using a primary AMR. NOTE: An AMR is not included with this motherboard.
