2.5 Installing DDR DIMM
The procedures for installing DDR DIMMs are described below. Please
follow these steps carefully. You can install SDRAM memory modules
using 184-pin DDR DIMMs (Small Outline Dual In-line Memory Mod-
ules).
1. Ensure that all power supplies to the system are switched off.
2. Tilt the DDR DIMM card slightly above the board, and move it in
the direction of the housing card slot. Make sure that the key in the mod-
ule and the key in the housing are aligned.
3. Push the module into the socket until the module bottoms out.
There should be a slight insertion force to engage the module into the
contacts.
2.6 IDE Drive Connectors (CN22, CN24)
The board provides two IDE connectors for connecting IDE drives to the
motherboard. The IDE controller on the motherboard supports IDE
devices running in all modes up through ATA-100. There are two IDE
drive connectors. Each connector supports two drives, a “Master” and a
“Slave” which connect to the motherboard with a ribbon cable. The sup-
plied cable supports transfer modes through ATA-100.
2.6.1 Connecting the hard drive
Connecting drives is done in a daisy-chain fashion. This package includes
One 44 PIN IDE cable that can connect to 1.8" and 2.5" drives.
1. Connect one end of the cable to the Hard Drive connector. Make
sure that the red (or blue) wire corresponds to pin 1 on the connec-
tor, which is labeled on the board.
2. Plug the other end of the cable into the Enhanced IDE hard drive,
with pin 1 on the cable corresponding to pin 1 on the hard drive.
(See your hard drive’s documentation for the location of the con-
nector.)
If desired, connect a second drive as described above.
Unlike floppy drives, IDE hard drives can connect to either end of the
cable. If you install two drives, you will need to set one as the master and
one as the slave by using jumpers on the drives. If you install only one
drive, set it as the master.
