Chapter 8: PCI Configuration Viewer
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.
