7.2 Modem Riser
7.2.1 56K Software Modem
The Modem Riser (MR) is a high-speed PC
communication peripheral which works with
AMC97/MC97 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.

2. Open the computer chassis and re-
move the metal plate on the AMR ex-
pansion slot.
3. Carefully align the MR cards connec-
tor to the AMR slot and press firmly.

with the screw removed in step 2.
5. Connect the MR cards LINE connec-
tor to a telephone wall jack. Connect
the PHONE connector to a telephone
(optional).
