Does This Board Have PCI Express (lspci)


Unfortunately I don't have physical access to this box, nor do I have the specs on the mainboard --I need to know if it has a PCI Express slot. Using lspci -v I get the following. Is it "Capabilities: [d0] Express Root Port (Slot+), MSI 00" --and is that a combo slot?


Code:
[...]

00:06.0 PCI bridge: Silicon Integrated Systems [SiS] PCI-to-PCI bridge (prog-if 00 [Normal decode
])
        Flags: bus master, fast devsel, latency 0
        Bus: primary=00, secondary=02, subordinate=02, sec-latency=0
        Capabilities: [b0] Subsystem: Silicon Integrated Systems [SiS] Device 0000        Capabilities: [c0] Message Signalled Interrupts: Mask- 64bit- Count=1/1 Enable-
        Capabilities: [d0] Express Root Port (Slot+), MSI 00
        Capabilities: [f4] Power Management version 2
        Capabilities: [100] #1039
        Kernel driver in use: pcieport-driver

lshw will ID the actual board, and then you can look up the specs.

lshw segfaults. I'm pretty sure this can be gleaned from lspci --just hoping someone can help interpret the capabilities listed.

There's *really* not quite enough information listed there to make a definitive determination.

Based solely on the driver being used (which is infact a pciE port driver), I went here (supported devices by that driver):
http://hardware4linux.info/module/pcieport-driver/
and selected just ONE of the SiS devices and followed that link to here:
http://hardware4linux.info/type/13/
and again selected an SiS device based on the #1039 shown in the capabilities on your lspci listing, so I got here:
http://hardware4linux.info/pci/1039/

.. so you see, it's really hard to figure out exactly what we're looking at.. If you can maybe run `dmidecode` and/or `hwlist` on the machine (or put a working copy of lshw in there) we could perhaps make some determination. `dmidecode` should provide all the info we need to identify the motherboard (provided its identity fields are actually filled in).
