Hi, I've recently updated some 100 Precision 3630 PC's with Precision_3630_2.4.2.exe. Problem is I can't find the specs on this update anymore. What I can find is BIOS 1.5.0 The date on this is newer but when I try to install the logs tell me I can't downgrade. What is with this versioning and why can't I find anything for 2.4.2 anymore?
