Hmm, I'm running Linux on my Y500. Any ideas/tips on how to use the "official" v2.02 (current version is v1.03)? I guess the InsydeFlash.exe is meant to be run on Windows and not on (Free)DOS. Once updated to v2.02 I should be fine, I can use a different machine (running some version of Windows) to create the USB using the tools provided. Thanks. [Edit] Managed to do a Windows network boot at work, problem solved. Both flashes successful, posting this from my Y500 with a fresh Intel 7260 network controller. Cheers!
