Figure 1-17. PCI Registers

Any bit in the PCI configuration space can be modified using the PCI Registers dialog box. A new value can be directly typed into the “New Value” edit box or entered by pressing any of the bit numbers below the edit box. The new register value will not be written until the “Write” button is pressed. Note that by hovering the cursor over the bit numbers a description for the bit appears.

TopHat has many other features. One useful feature is to rescan the PCI bus. For example, while testing hot plug a user might remove one endpoint device and replace it with another. By pressing the rescan button, the new device will now be present the PCI hierarchy. To rescan the PCI bus, press the magnifying glass below the toolbar.
