After inserting floppy into the drive, you can read and write data. The capacity of floppy disk is less than your hard disk however, it is easily carry on your hands and smaller than other disk drives. Using floppy disk Always make back up files for your important information. Keep your floppy disk in a safe space. Use the label part when you pick up or hold the floppy disk. Attach labels after writing letters on it. Handle disk with care. Use only one label to each floppydisk. Keep floppy disk away from magnetic prod uct such as TV. Keep floppy disk from direct sunlight. when inserting the floppy disk, label should face upward. Prohibiting data access into the floppy With this floppy disk. you can read, write, delete and change data. But by positioning the tap as shown on the right, you can only read data from the disk. read/write Read only Note When the floppy disk status indicator is on, do not attempt to take floppy out of computer. Using the system 39 Using the Hard Disk Drive The hard disk drive is an auxiliary memory installed in the computer. The hard disk drive reads and writes data at a fast speed and saves large amount of data. As both the disk and the disk drive are installed in the hard disk, the "hard disk" and the "hard disk drive"

are used as the same terms. After installing a new hard disk, set up the system and for-

mat the hard disk while referring to the "System Setup" part. Upon Data Damage in Hard Disk. A hard disk is sensitive to the external environments and shocks. The manufacturer is not responsible for data loss or damage of the hard disk caused by errors. Therefore, it is recommended to back up important data. Notes on Removal or Separation of the Computer Before removing or installing a computer, turn off the computer and correctly connect cables. In the case where cables are incorrectly linked, the hard disk may get damaged. When installing a hard disk, use designated nuts only. Otherwise, defects may occur on the hard disk. If you uses thicker nuts than standard ones, critical damage may be done to electronic parts. For stable use of the hard disk, fix the hard disk in the main body of the computer without any gap or vibration. Notes on Operating Environment of the Computer The hard disk may get damaged by external shocks during transportation. Avoid direct sunlight and damp place because the hard disk is sensitive to high temperature and humidity. Cover the hard disk with a static electricity-resistant envelope. Put the hard disk away from appliances with strong magnets such as TV and stereo set. The hard disk can get damaged by an electric shock from lightning. It is recommended, therefore, not to use the computer during thunder and lightening, and disconnect the power cord when not using the computer. Notes on Operation of the Computer Shocks on the hard disk during transportation may cause file damage or bad sectors. When the computer is abruptly reset (rebooted) due to power failure, the hard disk may get damaged. The hard disk may get damaged when infected with computer viruses. BIO setup with wrong hard disk parameter values may damage the hard disk. If necessary files are deleted by your mistake, the computer may not properly function. Abrupt turning-off of the computer can damage the computer. 40 Using the system Disk Defragmenter The disk defragmenter will collect fragmented volumes so that the computer can operate effi-

About Memory This system uses a 240-pin memory module called Double Data Rate-2 (DDR-2), not the old 184-pin memory module called Double Data Rate (DDR). The main board can support maximum 2GB in memory. Note Windows 95, 98SE, and ME support maximum 512MB. Installing a memory with higher capacity than 512MB may cause malfunctioning of the system. Before Expanding the Memory When disassembling the computer, wear gloves to protect internal parts of the computer and slot cards from damage. As the memory is sensitive to static electricity, be careful with the static electrici-

ty when removing or installing a memory. Check the specifications of the current memory and the new memory before expanding the memory. Unlike SIMM, DIMM is of 64 bits. Therefore, single DIMM can function, and you can add DIMM by one. Note When expanding the memory, add a memory with the same specification (DDR-2 SDRAM for 1.8V). (The shape of the memory may differ depending on the product model.) The DDR-2 memory provides greatly improved transmission rate than existing memo-

ries, and is differently shaped. 74 System Expansion This computer supports PC3200/4300, DDR-2 specification. When expanding the memory, use only unbuffered DDR SDRAM DMM When inserting two same memories in same-colored DIMM slots, the computer will oper-

ate in Dual Channel mode. FSB Frequency Usable Memory 400/533 MHz PC3200/4300-DDR-2 SDRAM 400/533MHz Preparing a Memory Before purchasing memory, study the specifications and features of the current memory. Specification : PC3200/4300 (240-pin DDR-2 SDRAM) Rate Type
