1. The term Gigabit Ethernet does not connote an actual operating speed of 1 GB/sec. For high speed transmission, connection to a Gigabit Ethernet server and network infrastructure is required.
2. Up to 256MB of system m emory may be allocated to support graphics, depending on system memory size and other factors.
3. The total amount of usable memory available will be less than 4 GB, depending on the actual system configuration
4. For hard drives, GB means 1 billion bytes; actual capacity varies with preloaded material and operating system and will be less.
5. Di scs burned with this drive may not be compat ible with some existing drives and players ; using DVD+R media provides maximum compatibility.
