18 NP1100 10/100Mbps PCI Bus Fast Ethernet Card
YML567 Rev2
Troubleshooting
If you experience any problems with the adapter, first verify that the appropriate driver is
loaded, that the proper grade of cable is employed for the network connection, and that
the supporting hub is functioning properly.
1. Ascertain that the adapter card is fully and firmly seated in the slot connector.
2. Check the length and rating of connecting cables.
3. Ascertain that the adapter’s PCI slot is not deactivated at the BIOS level. The CMOS
Setup utility in PCI computers ordinarily provides the option to activate or deactivate
PCI slots.
4. Replace the adapter in question with a verified adapter and run DIAG.EXE diagnostic
tests on the 110/100Mbps Driver CD-ROM from the D:\DIAG\ directory (where “D”
is the letter of your CD-ROM drive).
5. Install the questioned adapter in another PCI computer and run the tests again.
Remove all other PCI adapters from the computer and run the tests again. If the
verification/diagnostic run is not normal, then there is probably an interrupt number
conflict which will have to be resolved manually by a CMOS Setup utility run after you
have reinstalled all of the expansion cards.
