The computer cannot start up from the correct storage drive or the message “No Operating System
Found” is displayed.
Solutions:
• Ensure that the signal cables and power cables for all the storage drives are connected correctly.
• Ensure that the computer starts up from the correct storage drive. Set the storage drive, on which the
operating system resides, as the first startup device in the Setup Utility program.
Note:
In rare cases, the storage drive with the operating system might get corrupted or damaged. If this
problem occurs, replace the storage drive.
Ethernet LAN problems
The computer cannot connect to an Ethernet LAN.
Solutions:
• Connect the cable from the Ethernet connector to the RJ45 connector of the hub.
• Enable the Ethernet LAN feature in the Setup Utility program.
• Enable the Ethernet LAN adapter.

.
• Update or reinstall the Ethernet LAN driver. See “Keeping your computer current” on page 26.
• Install all networking software that is necessary for your network environment. Check with your LAN
administrator for the necessary networking software.
• Set the same duplex for the switch port and the adapter. If you configured the adapter for full duplex,
ensure that the switch port is also configured for full duplex. Setting the wrong duplex mode might
degrade performance, cause data loss, or result in lost connections.
When a Gigabit Ethernet model computer is used at a speed of 1000 Mbps, the Ethernet LAN
connection fails or errors occur.
Solution:
Connect the network cable to the Ethernet connector using Category 5 wiring and a 100 BASE-T hub/switch
(not 100 BASE-X).
A Gigabit Ethernet model computer should connect to the network at a speed of 1000 Mbps but at
only a speed of 100 Mbps.
Solutions:
• Try another cable.
• Set the link partner to auto-negotiate.
• Set the switch to be 802.3ab-compliant (gigabit over copper).
