8. Install DIMM Modules
6. AMR Expansion Slots
AMR
is a riser card that supports sound or modern 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 (CODEC) circuit requires a different
and separate circuit design that is put on AMR card. This motherboard implements sound
CODEC on board (can be disabled by JP12), but reserves AMR slot for the option of
modem function. Please note that you can still use PCI modem card.
The DDR SDRAM interface allows zero wait state bursting between the SDRAM and the data
buffers at 200 or 266MHz. The two 184-pin sockets, four banks of DDR SDRAM can be
composed of an arbitrary mixture of 1M/2M4M/8M/16M/32M/64MxN SDRAM with maximum
up to 2GB. Besides, this motherboard is equipped with two 168-pin SDRAM sockets that
allow you to install PC100 or PC133 memory and can go up to 2 GB as well. When you install
both DDR and SDRAM modules, the SDRAM will be automatically detected first; however,
we strongly recommend you not to install both of them at the same time.

Warning: The AK76D supports both DDR
SDRAM and SDRAM, please do not install
the SDRAM on the DDR SDRAM sockets
and vice versa. Otherwise, it will cause
serious damage on memory sockets or
SDRAM module.

9. Connect IrDA Connector
The IrDA connector can be configured to support wireless infrared module, with this
module and application software such as Laplink or Windows 95 Direct Cable
Connection, the user can transfer files to or from laptops, notebooks, PDA devices and
printers. This connector supports HPSIR (115.2Kbps, 2 meters) and ASK-IR (56Kbps).
Install the infrared module onto the
IrDA
connector and enable the infrared function from
BIOS Setup, UART mode select, make sure to have the correct orientation when you
plug in the IrDA connector.
7. Connecting IDE and Floppy Cables
Connect 34-pin floppy cable and 40-pin IDE cable to floppy connector FDC and IDE
connector. Be careful of the pin1 orientation. Wrong orientation may cause system
damage.
