8.1 Scanning PCI Buses

To view the PCI Config Viewer Dialog select the "View→Show PCI Config Viewer” entry from the Main Window menu. To scan a PCI bus, you must first load a bsd file that contains a CPU device. The dialog should look like the one shown in Figure 8-1.

8.2 Modifying the PCI Configuration contents

To modify the PCI configuration registers of a specific PCI device, select a device listed in the PCI Config Viewers list box. The PCI Config Viewer shows the contents of all PCI configuration registers of the selected device. To modify a certain byte of a PCI configuration register, click on the desired hex value and enter a new hex value. To apply the changes, click on the „Apply Register Modifications‟ button.

Read-only bits cannot be modified using the PCI Config Viewer. Modified values appear in red in the PCI configuration register list until you click on the „Apply Register Modifications‟ button or close the PCI Config Viewer dialog.

To change the byte view of the PCI configuration registers to a dword view, check the „DWORD PCI Access‟ check box.
