6Quick Installation GuideTroubleshootingCheck the following troubleshooting items before contactingAccton Technical Support.PCI CompatibilitySome PCI computers are not self-configuring and require youto perform some or all of the following functions bymotherboard jumper changes and/or BIOS Setup programconfiguration:• Make sure your BIOS correctly supports the PCI LocalBus Specification v2.0 or later and upgrade your computerBIOS to the latest version.• Verify that the PCI slot is an enabled bus-master slot andnot a slave PCI slot. In some computers the PCI slot mustbe configured to enable bus mastering. Refer to your PC’smanual and check the PCI BIOS Setup program to be surethe PCI slot is an enabled bus-master slot.• In some computers, you may be required to disable Plug ‘nPlay (PnP) in the BIOS Setup program if resources are notproperly assigned between installed cards.• Some computers may require you to reserve interruptsand memory addresses for installed ISA cards to preventPCI cards from using the same settings. Refer to yourPC’s manual and check the PCI BIOS Setup programconfiguration 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 theslot where the Cheetah PCI Adapter is installed. Be surethe slot is configured for level-triggered interrupts insteadof edge-triggered interrupts.
