I am not sure that there is a way to do exactly what I think the OP is asking. In some MB the difference between 1, 2, 3 and 4 PCI slots is simply the presence of a connector. i.e. The chip set can support more than are wired on the PWB. It is possible to count the bridge2pci interfaces but empty pci slots cannot be seen as far as I know (jtag?). "Dmidecode reports information about your system's hardware as described in your system BIOS according to the SMBIOS/DMI standard (see a sample output). This information typically includes system manufacturer, model name, serial number, BIOS version, asset tag as well as a lot of other details of varying level of interest and reliability depending on the manufacturer. This will often include usage status for the CPU sockets, expansion slots (e.g. AGP, PCI, ISA) and memory module slots, and the list of I/O ports (e.g. serial, parallel, USB)." Since dmidecode is getting info from the BIOS it is possible for the vendor to know what the build list for the MB is and return the right info, but as far as I know software cannot "see" empty slots. Note also that many MBs have multiple PCI busses. Some are dedicated for resources on the MB. One or more will have connectors to plug stuff into. -- T o m M i t c h e l l spam unwanted email.
