What is a Base System Device?

I have an HP Pavillion 9628nr laptop.
3 Gb RAM
32-bit
AMD Turion 64 x2 Mobile Technology TL-58

It came with Vista Home Premium and I recently upgraded to Windows 7 Home Premium.
I also recently installed a BIOS upgrade. The BIOS is a Phoenix F.2A version 2.8.17.0
Now, when I run Device Manager I see some items for which there is no driver and I have no idea what they refer to. They each have an exclamation mark within a yellow triangle next to them.

Two are called "Base System Device"  and one says "Coprocessor."
When I open the properties I get the following information for the location of each:
PCI bus 2, device 5, function 3
PCI bus 2, device 5, function 2
PCI bus 0, device 1, function 3

Can someone tell me what these refer to?

I'd say you need to update the motherboard chipset drivers.

I believe the Coprocessor is refering to the display adapter. In any case, in the device manager, right click on the devices and select properties.
Then select the "Details" tab
Use Ctrl+c to copy the device instance ID strings.
Then paste them (Ctrl+v) in your reply.
I will post them for you in the morning if you still need them.

IT Pros Agree: AI and Machine Learning Key

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

PCI\VEN_1180&DEV_0592&CC_0880 = ricoh card reader
Try updating chipdet driver as well.

OK,
My Chipset is NVIDIA nForce 560 (northbridge and southbridge).
Unfortunately, it appears that my chipset has no driver for Windows 7 32-bit (See screenshot).
What do I do now?

For some reason on their web site if you search W7 it shows nothing, but if you search Vista it shows the driver is for Vista and W7.
You might go to HP's website and download the drivers there. They may have some customized chipset drivers there.
Vista drivers will work in a pinch. If you run them in compatibility mode.

Interesting! I tried to install the driver that your link pointed to but got a message the the installer could find no compatible hardware. So... I went ahead and installed the Vista version, rebooted. and now one of the three missing devices is no longer missing (See Screenshot).

Do you see any potential problems with running the vista driver? You mentioned running the vista drivers in compatible mode. How do yo do that?

Vista drivers will work no problem. Of course use W7 drivers if you can find them. Try to install normally but if you get any error messages such as "this OS not supported" or something, you can use compatibility mode.
To use compatibility mode, right click on the file, choose properties, and select the compatibility tab. Choose the OS level you want to mimic and run the App.
I have had about 80% success with this method on programs that would not run other wise.

Yeah, hmm, I must have screwed up the link, but you get the point....

For the others, try HP website and install the Ricoh card reader driver. W7 first, if not try Vista again.
