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 must be disabled when using a primary AMR.
IMPORTANT:
The AMR slot of this motherboard shares the same expansion slot
as PCI Slot 5. Because of this and its location, the slot can only accept a specially
designed AMR card (optional). The components of a standard AMR card and its
bracket face toward the edge of the motherboard while those of the specially-
designed card face the expansion slots. For availability, see your vendor or dealer.
