The drivers we have for chipset are for desktop boards, and since you are using a server system, our driver will not include some of the features needed to work with your workstation, so, the best thing to do in this case will be to get in contact with HP directly, they should be able to assist you with this.
The following link belongs to HP, is where you can get the drivers for your workstation, you should be able to find the chipset driver in there, not sure if this is the one you try already, but here is the link, just in case:
If the problem persists, then please get in contact with HP directly:
