Re: Generating EFI files

Hi Adam,

I was able to locate the QEMU settings needed and now can run all of the 
examples except the "L4Linux-Basic" one that reports and error of 
"Failed to map VGA area but CONFIG_VGA_CONSOLE=y." and stops at that point.

I think that this is a similar message that I get when I try to run any 
of them on physical hardware Intel i5 NUC7, Intel i7 NUC13, and Dell XPS 
8950 (11th Gen Intel(R) Core(TM) i7-11700 @ 2.50GHz   2.50 GHz) which 
reports that it cannot find a suitable video mode on all 3 systems.

The good news here is that we have made some good progress with getting 
most of the examples to run under QEMU which is a great start, my friend.

Thanks and have a wonderful day,
Lonnie
