TROUBLESHOOTING

PCI Compatibility

Early PCI BIOS versions do not properly support the PCI specification and may “hang” when a network card

driver tries to load. If this occurs, make sure your BIOS correctly supports the PCI Local Bus Specification

(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 EZ Card

1000 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 the EZ Card 1000

network card is installed. Ensure that the slot is configured for level-triggered interrupts

instead of edge-triggered interrupts. An example of typical PCI parameters follows:

- PCI Slot #: (slot number where the network card is installed)

- Master: Enabled

- Slave: Enabled

- Latency Timer: 40(range is 20 to255)

- Interrupt Type: Level-Triggered

- Interrupt Number: (choose any number the BIOS Setup supplies that does not conflict with

another installed card)

Note that the wording of these parameters varies with different computers, and not all parameters may be

configurable.

Always consult your computer manual for information on changing motherboard jumper settings and BIOS

Setup program parameters for use with PCI network cards. If you set a motherboard jumper and modify the

computer’s BIOS Setup, make sure the jumper and BIOS settings match.
