Test the Ethernet controller. How you test the Ethernet controller depends on which operating system you are using (see the Ethernet controller device driver README file). Ethernet controller troubleshooting chart: You can use the following troubleshooting chart to find solutions to 10/100 Mbps Ethernet controller problems that have definite symptoms. Controller problem The server stops running when loading device drivers. Action 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. (Refer to the "Getting Help Information" section of this Server Library for World Wide Web addresses.) Run the network diagnostic program. If the problem still exists, run the server diagnostic programs (see "Diagnostic programs" on page 10) and check with the LAN administrator. 58 Netfinity Server HMM

How you test the Ethernet controller depends on
which operating system you are using (see the
Ethernet controller device driver README file).

solutions to 10/100 Mbps Ethernet controller problems that
have definite symptoms.

loading device drivers.
The PCI BIOS interrupt settings are
incorrect.
Check the following:
