Quick Installation Guide
Troubleshooting
Check the following troubleshooting items before contacting
Accton Technical Support.
PCI Compatibility
Some PCI computers are not self-configuring and require you
to perform some or all of the following functions by changing
motherboard jumpers and/or configuring the BIOS Setup
program:
• Make sure your BIOS correctly supports the PCI Local
Bus Specification v2.0 or later and upgrade your computer
BIOS to the latest version.
• Verify that the PCI slot is an enabled busmaster slot and
not a slave PCI 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 busmaster slot.
• In some computers, you may be required to disable Plug ‘n
Play (PnP) in the BIOS Setup program if resources are not
properly assigned between 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.
• Be sure 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 Cheetah Gigabit Adapter is installed. Be
sure 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 to 255)
Interrupt Type: Level-Triggered
Interrupt Number: (choose any number the BIOS Setup supplies
that does not conflict with another installed card)
Note: 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.
