This page is primarily intended as an engineering resource for people who need to deal with computers built around the PCI bus. It’s reason for being is that there is no other centralized database of PCI device IDs. This database is entirely user-supported; all the data has been, and continues to be, furnished by those working in the PCI market. Feel free to add info for the use of others!
This is one of those things you find and you’re just glad someone took the time to do it. If you have any “unknown card” messages in your dmesg output, you can find out what they are.
pci0: <unknown card> (vendor=0x1106, dev=0x3057) at 4.4
From this I found out this is a ACPI power management chip from VIA technologies on one of my systems. ACPI is only supported in the -CURRENT branch of FreeBSD, so I can’t use it yet. But that message will go away when I upgrade to 5.0.
On my laptop, I found out I have a real hardware modem, not one of those useless software modems.
