7.2.1 56K Software Modem

The Modem Riser (MR) is a high-speed PC communication peripheral which works with AMC’97/MC’97 compliant codecs. With this software modem, you can connect your com- puter to a remote location, receiving data at up to 56 Kbps in V.90 or K56flex modes.

7.2.2 Primary/Seconday MR

There are two types of modem risers: primary MR and secondary MR. In appearance, the primary MR has a crystal onboard but the sec- ondary does not. If your motherboard has an audio codec and no PCI audio chipset on- board, you may use the secondary MR; oth- erwise, you should use the primary MR.
