The shape and replacement method of the CPU fan may be different depending on
the model.
1. Clamps on both sides of the CPU fasten the fan tightly to the CPU socket.

2. After releasing the clamps, lift and remove the CPU fan from the socket.
3. Raise the handle on the CPU socket to unlock the CPU.

Align the identifying marks at the corners of the new CPU and socket, and carefully
install the CPU in the socket. Lower the handle to lock the CPU in place.
6. Lift the clamps and slide them into the rails at the corners of the CPU socket, and
place the fan into the socket. Push down the handles to lock the clamps.
4. Lift the CPU straight up. Be careful not to damage the pins at the bottom of the CPU.
In some models, you can not lower one of the handles of the clamps all the way down.
For removing CPUs in these models, release the clamp on the other side first. For
installing CPUs in these models, lock this clamp first.

3-5. Increasing the memory
If you run out of memory while using the computer, you may want to increase the
amount of memory in your computer.
Note
Use a 2.5V DDR SDRAM DIMM.(The shape of the memory may be different depend-
ing on the model) DDR SDRAM enhances the rate of data transmission of the
SDRAM and looks different from SDRAM.
DDR
About memory
Your computer uses DDR(Double Data Rate) SDRAM DIMM(Dual In-Line Memory
Module) with 184 pins. Your computer supports Unbuffered DDR SDRAM DIMM of
128MB up to 1024MB in size in each socket, and 2048MB total.
Note: Windows 95, 98SE, ME supports memory up to 512MB total. Increasing the
memory beyond 512MB in these systems may cause errors while using the
computer.
Before increasing the memory
Static electricity can damage memory modules; be sure to minimize the static electric-
ity when replacing memory.
Make sure to replace the memory of the same type as the installed memory.
DIMM is different from SIMM in that it is configured for 64 bit operation; therefore,
your computer can operate with only one DIMM installed.
29System Expansion
Purchasing a memory
Check the type of memory installed in your computer and refer to the memory configura-
tion chart before purchasing a memory.
Specification: PC2700/3200(184 pin DDR SDRAM DIMM)
Speed: 333MHz(166MHz X 2), 400MHz(200MHz X 2)
Size: 256MB, 512MB

Replacing the memory
The main board configuration, memory socket, and the shape of memory may be dif-
ferent depending on the model.
1. Remove the screws on the real of the computer, and open the computer case.
1. Pull the latch on each side of a memory socket.
2. Align the notch at the bottom of the memory with a protrusion in the middle of the
socket, and then insert the memory straight down.
Note: Push the latch inward so that the memory is securely locked in the socket.
2. Pull the latch on each side of a memory socket to release the memory.
Installing a memory
Note: Before opening the case, turn off the computer and peripheral devices, and
remove the power cords.
31System Expansion
Checking the size of the installed memory
The computer automatically recognizes the newly installed memory; therefore, you do
not need to change the system setup. Follow the instruction below to check the size
of the installed memory.
1. Connect the power cord and other devices, and turn on the computer and monitor.
2. Press Delete when the following logo screen appears. In CMOS Setup Utility, select
Advanced BIOS Features. Change Full Screen Logo Show Selectable from Enabled to
Disabled. Press F10, and Enter to save the new setting.
3. The computer restarts. Press Esc at the logo screen shown above. If the following
screen appears, press Pause to stop and check the size of memory next to
Memory Testing.
4. Press Esc to continue the startup.

3-6. Adding a hard disk drive
Your computer supports up to 4 E-IDE controllers and 2 hard disk drives.
Before adding a hard disk drive
Adding a hard disk drive
The following instruction describes the most typical configuration where your comput-
er already has a master hard disk drive and you are adding a slave hard disk drive.
Note: Check and write down the jumper settings, size, and number of cylinders,
heads, and sectors of the hard disk drive where you can refer to when you use
the system setup. (Some hard disk drives do not have the information written
on the drive)
Note
Purchase an E-IDE hard disk drive.
Set the jumper setting to SL: Slave.
The jumper settings differ from one hard disk drive to another, so make sure you fol-
low the jumper setting information on top of the drive.
Jumper
Signal cable connector
Power connector
If the master hard drive is set to CS(Cable Select), the slave drive must also be
set to CS(Cable Select).
Using screws other than the ones provided with the hard disk drive can damage
the drive. Using longer or thicker screws can be fatal to the disk drive. A hard
disk drive must be mounted securely in order to provide reliable performance.

When connecting the signal cable to the hard
disk drive, be sure to align the tab in the mid-
dle of the cable with the notch on the connec-
tor of the hard disk drive. The notch and tab
prevent inserting the cable upside down.
Depending on the hard disk drive, the notch
may be at the bottom of the connector.
