Aug 15, 2012  I have installed Windows XP SP3 from an ISO and I am getting some driver issues. There is 1 Unknown Device with device instance id ACPI VMBUS 4&4B018EB&0 I am hoping that this is my network card, since I do not see a network card installed. I am also getting the yellow exclamation point on the Video Controller.

I recently had to reinstall windows on my laptop after the hard drive crashed 1 month out of warranty. I had a few unknown devices on the PCI Express Root and I was able to find the fix for 2 of them through these forums simply by searching either the hardware id value or the device instance path value. However, I have yet to be able to find the proper driver for the following unknown device: Hardware Id details: ACPI VEN_SMB&DEV_0001 ACPI SMB0001 *SMB0001 Device instance path details: ACPI SMB0001 3&11583659&0 Thank you for your assistance.
