Viewing NIC status
The information displayed on the NIC Status tab might help you to quickly identify a
problem. The NIC Instance list box contains a list of the adapters that are found in
your system. This list is obtained from the registry.
On Windows NT 4.0 systems, the token-ring PCI adapters are listed in:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows_NT\CurrentVersion\
NetworkCards. The token-ring PCI instances are listed in:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\IBMTRP.
On Windows 9x systems, the token-ring PCI instances are listed in:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Net\.
On Windows 2000 systems, the token-ring PCI instances are listed in:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\Current Version\Network
Cards\# in the registry variable 'ServiceName'.
To view NIC status, complete the following steps:

IBM 16/4 Token-Ring Low Profile PCI Management Adapter
The information for the instance you selected displays in the fields. This
information includes:
v MAC address. This is the address of the NIC encoded in the adapter memory
at the factory. This address can also be found on the adapter card label. This
is a unique address that the network software uses to distinguish the adapter
from others in the network
v Transmit/Receive Test. The transmit/receive test indicates the number of
packets being transmitted and received without errors by the adapter. These
counters are updated approximately every 2 seconds. If the transmit and
receive fields are being incremented, traffic is being processed by the
adapter. If no other stations are on the ring, these counters will increment
very slowly.
v Hardware status. This is the current status of the NIC. The status is
represented by the following values that correspond to the
NDIS_HARDWARE_STATUS-type values:
Status NDIS_HARDWARE_STATUS-type
value
Ready NdisHardwareStatusReady
Initializing NdisHardwareStatusInitializing
Resetting NdisHardwareStatusReset
Closing NdisHardwareStatusClosing
Not Ready NdisHardwareStatusNotReady
v Ring state. This is the state of the NIC with respect to entering the ring. The
ring state is represented by the following values that correspond to the
NDIS_802_5_RING_STATE values:
Status NDIS_802_5_RING_STATE value
Open NdisRingStateOpened
