Problem : After installing the Oxygen card, network problems
appeared.
Solution : There may be a conflict between your Ethernet card and
your Oxygen card. If your Ethernet adapter is an ISA adapter rather
than a PCI adapter, then check system diagnostics for IRQ conflicts.
(
The Oxygen 202 card requires two and the Oxygen 402 card requires
four of the PCI interrupt lines, which your system may assign to one or
more IRQs. Other PCI devices may share these same IRQs.)
To solve this problem, from the Start Menu, select Programs then
Administrative Tools and run Windows NT Diagnostics. Then click the
“Resources” tab. Make sure the IRQ button is selected and check for
any devices sharing IRQ settings.
If two IRQs conflict, then change the Ethernet IRQ in the Network
Control Panel applet. Click on the Adapters tab, then select your
network adapter and click “Properties” to change the IRQ setting to an
open IRQ number. For additional details, consult your Ethernet
adapter documentation or vendor for information on changing IRQ
settings or for obtaining a newer Ethernet driver for your adapter.
Problem : After installing an Oxygen 202 card or an Oxygen 402 card,
network problems appeared.
Solution : Your Ethernet adapter software driver may be unable to
process requests. If using a PCI adapter and your system has more than
three (3) PCI slots, you should try changing the relative positions of the
Oxygen and Ethernet cards within PCI busses. More than three (3) PCI
slots implies that your system is bridging a second bus and the
configuration may be incompatible with the Oxygen 202 or Oxygen
402. Updating the Ethernet adpater’s driver and/or re-installing the
driver software may be required.
