Pci Bios Settings; Pci Interrupts - Adaptec PCI Ethernet and Fast Ethernet Adapters User Manual

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
Use this setting to enable all PCI slots in your
system.
Bus Mastering
Use this setting to enable PCI bus mastering.
PCI INTA
Use this setting to assign an ISA interrupt (10, 11,
12, etc.) to PCI Interrupt Vector A.
PCI INT Vector
Use this setting to assign PCI Interrupt Vector A to
the PCI slot(s).
PCI Bus Latency
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.
