Modem Riser

7.3.3 Hardware Installation Procedure

7.3.1 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.

7.3.2 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.
