is a riser card that supports sound or modem function. Because CPU computing power is
getting stronger, the digital processing job can be implemented in main chipset and share CPU
power. The analogical conversion (
) circuit requires a different and separate circuit
design, it is put on AMR card. This motherboard implements sound CODEC on board (can be
disabled by JP12), but reserve AMR slot for the option of modem function. Note that you can still
use PCI modem card.
