Dunno how to do the same core-i7 of my laptop... Didier I just flashed the EFI/BIOS on my I7 XPS-13 several days ago. For non-Windows machines you copy the provided DOS ".exe" to a USB, restart the machine, and hit F12 (nearly always on Dell) and select "Flash / update the BIOS" or something close to that, after which just follow the instructions. Most newer Dell machines have the SA-00086 updates available. Older machines might not. Here's the relevant link: Dell intel flash patches for meltdown/spectre <http://www.dell.com/support/contents/us/en/19/article/product-support/self-support-knowledgebase/software-and-downloads/support-for-meltdown-and-spectre>
