you are able to select the driver package of which type of dell machine you want. Therefore you have to go to:
Patch and Compliance -> Download updates -> expand Driver Updates -> expand HII Drivers -> expand Tablet -> select Tablet-7130
now the patch manager download only the needed driver for this dell type.
That's what I thought as well, except I only had the Tablet-7130 selected and it was still downloading everything... I finally killed vaminer.exe and the downloads stopped. But, now when I select the Tablet-7130 option and try to download, the status window says it's downloading tablet-7130.xml and no updates are required, even through there's no drivers downloaded...
This makes me think there's a status file someplace that's telling LD that it already downloaded the drivers. Or, the Tablet-7130.xml file at Dell is empty/broken/etc and there's nothing to actually download. (The download log shows it as 0k...)
