Issue What to Do
How to configure an unrecognized
video display device manually.
If hardware limitations or inadequate information
from the BIOS prevent proper identification of a
video display device, manually configure the
device using the kdmconfig software interface.
How to verify the configuration of
video display devices.
Check the sample display provided after
configuration and click to accept the
configuration. If the display looks wrong or you
can’t click on the button, use the kdmconfig
software to change the device parameters, and
accept the configuration when the sample display
looks correct.
Ethernet Device Configuration
Duplex Settings
An Ethernet adapter and its link partner (such as a hub, switch, or another network
adapter connected via a crossover cable) must operate at the same duplex settings.
If the adapter and link partner support NWay media autonegotiation, both devices
should automatically select optimal speed and duplex mode.
If NWay autonegotiation is not supported or is not configured on either the
adapter or its link partner, both devices must be explicitly set to run at the same
duplex mode. A device usually defaults to half-duplex operation if it can’t
determine the link partner’s duplex capabilities.
A hub or switch that supports full-duplex operation usually has a mechanism
that sets duplex mode on a per-device or per-port basis. Setting speed, duplex
mode, or both in this manner usually disables NWay autonegotiation for the
device or port.
A network adapter supported by the elxl, iprb,ordnet device driver must
have its duplex mode set in the driver’s .conf file. See the device driver man
page for details.
Operating speed can sometimes be set in the driver’s .conf file, but NWay
autonegotiation may be disabled when using this method.
A device is usually able to detect the speed (but not the duplex mode) of its
link partner, even without NWay autonegotiation.
