XPS 8940, Fast Boot BIOS settings

This is what the Service Manual has for that setting:

============

Fastboot Enable to set the speed of the boot process.
Default: Thorough

===========

The XPS is probably fast enough that you can take the default (I do).

I'd say that most of the times it will not find a problem though. However, if you were to use either of the other 2 vs. the default, it is possible on a failure it could be missed?

Although not documented, I 'assume' Minimal doesn't run the full set of test on a device, and Auto might run Minimal most of the time unless h/w were changed and then it would run Through. (Just my guess on these).

If it boots fast enough for you, I'd stay with the default.

Method 1
What you need is the key F12 to open the boot screen and select USB boot. Follow these steps:

• Turn off your laptop.
• Now, plug in the USB drive that you want to use to boot your system. Mostly, the name of a USB drive will be the same as the brand of the USB.
• Next, switch on the laptop. It is better to keep the laptop plugged for charging as you do not want the system to shut down due to low battery during boot.
• Now, press the F12 key on the keyboard.
• You will find the boot options screen. Here select the USB drive to boot.
