First of all, this is the Intel Desktop Boards support forum. Desktop boards do not use IPMI; this is a server technology. Secondly, PCI and PCIe support is built into almost all O/Ss. In the case of Windows, as an example, the only related install package is the INF Update -- but it just installs configuration information that is used by the drivers that are built into Windows (i.e. it installs no drivers).
In order to help you further, we would need more information. What board are we talking about? What O/S are you using?
