I have a Lenovo T500, which came preinstalled with Windows Vista Business. All the hardware components were working perfectly.
I took advantage of the Windows 8 upgrade offer from Microsoft and performed an installation.
Windows 8 automatically installed most drivers by itself, but there are three entries in the device manager that are not working:
The hardware IDs for the devices that are missing are as follows:
First Base System Device:
Second Base System Device:
PCI Simple Communications Controller:
http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-70443 only has support up to Windows 7.
Please let me know how to identify what these devices are and also, where do I find drivers?

While I have no information about availability of Windows 8 drivers, searching at: http://www.pcidatabase.com/index.php yields the data below on your three problematic devices. There are some reports of Windows 7 drivers working in Windows 8, but I can't confirm personally.
Device Id Chip Description Vendor Id Vendor Name
0x0592 Rioh Memory Stick Controller 0x1180 Ricoh
0x0843 Ricoh SD/Host Controller 0x1180 Ricoh
0x2A44 Intel Management Engine Interface 0x8086 Intel Corporation
Hopefully, this info will help a bit.
I am not a Lenovo employee

Did you get a resolution on this? I've got the same problem with those three devices showing up as unknown with Windows 8...
