This is a notes page so I can collect the info needed to get this theoretical machine working properly. Bah.

- How to install Ubuntu on a Dell XPS 13 (9343) developer edition configured for Unified Extensible Firmware Interface (UEFI) BIOS
Bios Update
Just download the A05 and put 9343_BIOS_Rev_A05.exe
on a USB drive, and press F12 at boot. Choose BIOS Flash Update, and it should see the file as an option on the file select modal. The device must be plugged in to proceed. It will reboot, and it only takes a minute.
Selecting the boot file
Kinda following the directions Dell gives, I was able to select the boot file the computer needs to read to select Ubuntu from the drive. Kinda insane, I’ve never had to do that before, but once I selected it, it worked.
So far everything is working really well, and the machine is awesome. So here’s hoping nothing else breaks.
