I have two identical 6930s in like-new condition. I want to upgrade the BIOS from ver. 3121 to ver. 3238. I have the .exe file for the 3238 version, but I don't have any OS installed now, just a pristine and bare SSD. I will run it under Linux Mint ver. 22.1 Xia — after I update the BIOS. Any ideas how that can be done, as the Phoenix BIOS utility has no BIOS update option at all. The other issues, I have been running LM Linux Mint Cinnamon, Mate, and Xfce off of USB sticks before installing them for real after I update the Aspire's BIOS. All seems fine, except for the fact that Linux shows my LCD screen being a 4:3 aspect ratio 1024x768 XGA resolution screen. Whereas of course it is a 16-inch 1.77:1 AR 1366x768 pixel WXGA screen (CCFL panel w. 30-pin connection). No idea how and why LM would misidentify a 16:9 screen to a 4:3 aspect ratio screen. Any ideas where the troubles lies?
