Issue #1 - I kicked off the BIOS install from within Windows. It rebooted into the BIOS setup (what I'd call a DOS environment). I saw a message that said something like "flash complete". System rebooted, but never got to POST. I let it sit in that state for a few minutes, but it never made any progress. I know it didn't boot into the OS because there was no disk activity, LED's on USB kbd weren't on.
I power cycled the device. Still wouldn't boot. Tried removing the DisplayPort cable. Still didn't boot. Reconnected DP, removed HDMI. NOW it booted.
Issue #2 - I get a garbled GFX image when I try to enter the firmware setup page. This is right after pressing F2, or when trying to access it via Settings -> Update and Recovery -> Recovery -> Advanced Startup -> Restart Now (and then pick the UEFI firmware settings option).
I'd like to get some guidance from Intel before trying to either re-flash the same rev, or try going back to an earlier rev.
