Loaded Windows 7 Ultimate to a W500 4058CTO. Device Manager initially showed 4 devices without drivers.
Listed under Other Devices; 3 were Base System Device(s) and one is a PCI Simple Communications Controller.

Allowed Windows Update to search for drivers. One of the Base System Device(s) was found. It is a PCMCIA adapter - Ricoh R/RL/5C476 (II) or compatible CardBus Controller.

One remaining Base System Device(s) is listed as: PCI bus 21, device 0, function 4
The other is listed as : PCI bus 21, device 0, function 3
The PCI Simple Communications Controller is listed as: PCI bus 0, device 3, function 0

What are these devices and where can I get the drivers to support them?

You might try installing Lenovo System Update, it should find and install all the necessary drivers.
