Re: Generating EFI files

Hello Adam,

Yea, I found the "make help" after sending off the messages and was able 
to take the latest "snapshot" (non-git) and build things, but have had 
only limited success in running them on my Intel NUC13 Ubuntu 23.10 
(x64) system.

I can run the "hello*.efi" versions with the "make qemu" but it seems 
that the framebuffer example cannot map a VGA screen and it might be 
something in the "dtc" which is the hardware settings for L4Re, if I 
read the documentation correctly, but am not sure on this.

Interestingly, is that if I take the "git" version of l4re and build 
things with "ham" then the framebuffer example will run under qemu with 
"make qemu" to execute it. the l4linux-mag will boot up the graphics but 
then it just shows a blank window and I suspect that the same errors 
(below) are happening with the errors " terminate called after throwing 
an instance of 'N2L413Runtime_errorE'"

For bot the git and non-git builds, the VM-multi and VM-multi-p2p 
examples l4re boots and I make it through SIGMA0, MOD, and NED while the 
Console Server also boots up, but then I get and errors in the VM's 
starting:

I think there is some VGA video problem somewhere that is preventing the 
VM's from completely booting up for some reason.

Best and have a great day,
Lonnie
