The integrated Ethernet controller might display messages from the following device
drivers:
• Novell™ NetWare™ or IntraNetWare Server ODI
• NDIS Adapter for level 4.0 (Windows NT)
• SCO™ UNIX LLI

Ethernet controller problem Suggested Action
The server stops running
when loading device drivers.
The PCI BIOS interrupt settings are incorrect.
Check the following:
• Determine if the interrupt (IRQ) setting assigned to the Ethernet controller is also
assigned to another device in the Configuration/Setup Utility program.
Although interrupt sharing is allowed for PCI devices, some devices do not
function well when they share an interrupt with a dissimilar PCI device. Try
changing the IRQ assigned to the Ethernet controller or the other device. For
example, for NetWare Versions 3 and 4 it is recommended that disk controllers not
share interrupts with LAN controllers.
• Make sure that you are using the most recent device driver available from the
World Wide Web.
• Run the network diagnostic program.
Data is incorrect or sporadic. Check the following:
• Make sure that you are using Category 5 cabling when operating the server at 100
Mbps.
• Make sure that the cables do not run close to noise-inducing sources like
fluorescent lights.
The Ethernet controller
stopped working when
another adapter was added
to the server.
Check the following:
• Make sure that the cable is connected to the Ethernet controller.
• Make sure that your PCI system BIOS is current.
• Reseat the adapter.
• Determine if the interrupt (IRQ) setting assigned to the Ethernet adapter is also
assigned to another device in the Configuration/Setup Utility program.
Although interrupt sharing is allowed for PCI devices, some devices do not
function well when they share an interrupt with a dissimilar PCI device. Try
changing the IRQ assigned to the Ethernet adapter or the other device.
The Ethernet controller
stopped working without
apparent cause.
Check the following:
• Run diagnostics for the Ethernet controller.
• Try a different connector on the hub.
• Reinstall the device drivers. Refer to your operating-system documentation and to
the ServerGuide information.
