Hello All,

I have been experimenting with L4Re and was able to compile the latest 
snapshot that seems to work well for almost all of the examples in QEMU 
from the "make qemu" menu which is a very good start, I think.

Lately, I have also used the "make grub2iso" which gives me the same 
menu of examples as the "make qemu" but for which it will generate an 
ISO of the example.

I generated ISO's for all of the examples and tested them on 3 different 
x64 computer systems which are all Intel with 2 being NUC's and 1 being 
a Dell XPS 8950 but when I boot any of the generated L4Re ISO's, it 
seems to boot all of the core modules but then gets to an error message 
that seems to be related to the video mode.

-------------------------------------------
error: no suitable video mode found
-------------------------------------------

And then the screen shows a bunch of lines.

I have been looking around though the L4Re code in the snapshot release, 
but I do not yet have a clue where how to change things so that these 
ISO's will boot completely on some hardware although things seem to boot 
up in QEMU.

I am thinking that there might just be some setting somewhere that I 
need to adjust, or something.

Any thoughts, suggestions, or ideas would be greatly appreciated.

Have a great evening,
Lonnie
