Chapter 4: Address Selection - ICS Advent PCI-DIO48 Series Product Manual

Chapter 4: Address Selection

These cards use one address space, occupying sixteen consecutive register locations.
PCI architecture is inherently plug-and-play in nature. This means that the BIOS or Operating
System determines the resources assigned to PCI cards rather than you 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.EXE utility program. This
utility will display a list of all of the ICS Advent cards detected on the PCI bus, the addresses
assigned to each function on each of the cards, and the respective IRQs allotted.
Alternatively, some operating systems (Windows95/98/2000) 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 cards are 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.
PCIFind uses the Vendor ID and Device ID to search for your card, then reads the base address
and IRQ assigned. If you want to determine these yourself, the Vendor ID is 494F (ASCII for
"I/O") and the Device IDs are:
PCI-DIO48(S): 0C60
PCI-DIO48(S)S: 0E60
The PCI bus supports 64K of I/O address space, so your card's addresses may be located
anywhere in the 0000 to FFFF hex range.
