Have you used the "Show latest SoftPaq's" in the upper right of the All Available Softpaq's pane? This only works when selecting one platform and one OS at a time.
This will not remove all instances of the duplicate deliverables but it may reduce a few.
The main issue is how a deliverable is released. If it is set to supersede the previous version then the previous will disappear with the show latest version button. However there are some deliverables with broken supersede chains in which multiple versions will continue show up.
These issues you are seeing is something we are aware of and are working to fix for all future releases but those already released are a bit harder and slower to resolve.
Again I am sorry for the issue you are seeing but going by the latest SoftPaq number is your best bet today along with the Show latest button.
I need the driver packages for integrating them into SCCM. So I typically choose several models of a series e.g. 2170p, 2570p, 8470p/w, 8570p/w and one OS e.g. Windows 7 Enterprise x64 / x86. Then I search for the avaiable softpaqs and choose the newest ones(normally the highest softpaq number if there are several ones for one hardware). Then I download the softpaqs, use SSM to create the database. In my tasksequenz I use this package to install the drivers for my hardware models, I choose "Install Software" and as criteria for the right series I make WMI to the Base Board ID. So I can have different packages for different hardware (e.g. HPxx40 series, HPxx60 series, HPxx70 series,...) in one tasksequenz.
So it would be nice to have all actuall softpaqs for one series in one download package, just like the "HP Business Notebook xx70/xx75 Windows 7 x64 Driver Pack". I tried these packages, but it does not function for me, because not even all drivers were installed and we had to install some software packages later.
Also it would be nice when the sorting in the SoftPAQ download manager can be done in this matter: 1st Name, 2nd SoftPAQ Number, 3rd Version. In this case you can see the latest softpaq for a hardware is at the beginning of the list.
I see how you are creating your own driver packs and am glad to see that you are at least able to get a functioning system.
I am not aware of any driver package issues for the xx70 series. If you could provide me with the systems and device ID's of the remaining bang outs after using a driver pack I would be more than happy to look into it.
Today we post all our packages and the latest versions here.
