"The only thing that's different is the thing you said was different." :) It looked strange to me because I have two systems with a VT8237R and on both, lspci says "VT8237" for both the PCI and the ISA bridges. So the result provided by Etienne suggests that a different (supposedly earlier) version of the VT8237R has a different ISA bridge sub-device embedded. Not that it really matters, anyway, so I probably shouldn't have commented on it in the first place. > Or it looks like there's another of these "strange" cases: > > 0000:00:01.0 PCI bridge: VIA Technologies, Inc.

South bridges include several sub-devices, and it is very frequent that chip manufacturers do not upgrade all these sub-devices when they release a new version of their chip. My original comment was really related to the specific case of the VT8237R, not general. Thanks, -- Jean Delvare
