hubs
o PciMechanism: Specify the mechanism access to the PCI
configuration space.
o AutoDetect Detect the system's PCI mechanism

256 bytes
512 bytes (default)
1024 bytes
o UnderrunThreshold = REG_DWORD number_of_underruns (default=10)
Maximun number of underrun occurences before the
controller switches to StoreAndForward mode.
8. Click [Close] and [OK] to complete the driver installation.
9. Shutdown and reboot the system.
10. Installing multiple PCI boards:
Repeat the procedure above.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
