Installing Your Adapter
PCI BIOS Settings
PCI BIOS configuration options vary widely by system. The follow- ing section discusses representative PCI configuration options, but may not exactly match your computer. (Some computer BIOSs pro- vide no PCI configuration options, but instead automatically config- ure all PCI settings. Your BIOS may not provide the options described below). We recommend that you configure all PCI slots in your system, even those not currently in use, for later convenience. Enter your computer BIOS Setup, and select Advanced Settings from the Main Menu.
PCI Slot Enabled
Bus Mastering
PCI INTA
PCI INT Vector
PCI Bus Latency
Use this setting to enable all PCI slots in your system.
Use this setting to enable PCI bus mastering.
Use this setting to assign an ISA interrupt (10, 11, 12, etc.) to PCI Interrupt Vector A.
Use this setting to assign PCI Interrupt Vector A to the PCI slot(s).
Configure this setting to a value between 40 and 80.
PCI Interrupts
PCI uses an interrupt architecture that maps PCI interrupts to regu- lar ISA interrupts. Some PCI BIOSs will refer directly to the numeric ISA interrupts (i.e., 10, 11, 12) for PCI slots. Other BIOSs will refer to the PCI interrupt used by the slot (i.e., INTA, INTB, INTC, INTD).
All Adaptec PCI adapters use the PCI interrupt INTA, and the ISA interrupt to which it is mapped.
