3. the PCI bus The address spaces are defined in the programming section of this manual PCI architecture is Plug and Play This means that the BIOS or Operating System determines the resources assigned to PCI cards rather than the user selecting those resources with switches or jumpers As a result you cannot set or change the card s base address or IRQ level You can only determine what the system has assigned To determine the base address that has been assigned run the PCIFind utility program This utility will display a list of all the cards detected on the PCI bus the addresses assigned to each function on each of the cards and the respective IRQs Alternatively Windows systems can be queried to determine which resources were assigned In these operating systems you can use either PCIFind or the Device Manager utility from the System Properties Applet of the control panel The card is installed in the Data Acquisition class of the Device Manager list Selecting the card clicking Properties and then selecting the Resources Tab will display a list of the resources allocated to the card The PCI bus supports 64K of I O address space so your card s addresses may be located anywhere in the 0000h to FFFFh range The card occupies eight consecutive 8 bit registers in I O address space PCIFind uses the Vendor ID and Device ID to search for your card then reads the base address and IRQ If you want to determine the base address and IRQ witho
