PCI Compatibility

Early PCI BIOS versions do not properly support the PCI specifications and may “hang” when a network card driver tries to load. If this occurs, make sure your BIOS correctly supports the PCI Local Bus Specifications (v2.0 or later) and upgrade your computer BIOS to the latest version.

Some PCI computers are not self-configuring and require you to perform some or all of the following functions by motherboard jumper changes and/or BIOS Setup program configuration:

•Verify that the PCI slot is an enabled bus master slot and not a slave PCI slot. The network card must be installed in a PCI bus master slot. In some computers the PCI slot must be configured to enable bus mastering. Refer to your PC’s manual and check the PCI BIOS Setup program to be sure the PCI slot is an enabled bus master slot.

•In some computers, you may be required to disable Plug-and-Play in the BIOS Setup program if resources are not properly assigned between the network card and other installed cards.

•Some computers may require you to reserve interrupts and memory addresses for installed ISA cards to prevent PCI cards from using the same settings. Refer to your PC’s manual and check the PCI BIOS Setup program configuration options for ISA cards.

•Make sure the PCI slot is configured to support INTA.

•Ensure that INTA for the slot is assigned to a free interrupt (IRQ) number.

•Check the BIOS Setup program’s PCI parameters for the slot where
