The southbridge (ICH in Intel-language) doesn't contain the keyboard or mouse controller, floppy, or other low speed devices. Instead, those are on a Super I/O chip that is attached via the LPC bus to the ICH. The ICH contains medium speed things like sound, ATA, USB, ethernet, etc. > Adding device eisa can cause problems.

Justin Gibbs and I fixed one hanging problem with the EISA probe a few years back. I'm not sure if there are others. -- Nate
