After replacing the CMOS battery on a laptop, the BIOS (And everything up to the Windows welcome screen) began to be displayed on the external screen by default. In the BIOS itself, from the settings, only change the date / time and choose from which you can boot by default. In general, there are very few settings and you cannot configure which screen to display the BIOS itself on. But you can boot into the EFI Shell. Maybe there is some way to set it up? Change BIOS settings file? Only here I could not dig anywhere about where this file lies. And in general, there is practically no (and there is no Russian-language at all) information about EFI Shell on the Internet.

Everything is very indistinctly told ...
But in 2 words:
- BIOS and EFI Shell are alternatives (or one or the other)
- there is no "file with BIOS settings" - BIOS is written in EPROM (chip).
- somewhere you (in the BIOS, EFI Shell) should have a switch to select what to use when booting: BIOS or EFI Shell.
