Thank-you Mathew its given me some hope . Seems that I need to be more 
diligent and will reread the relnotes and updating notes from 12.4 
through to 14.0R

Robert, I think you're right.  I installed the 14.0-RELEASE before I 
noticed the efi check-box.  so yes I suspect a problem with my 
14.0Releng build (though I used the same settings for make.conf, 
src.conf as I use in 13.2 and 12.4).

However when using a FreeBSD(32bit) virtual machine using 
FreeBSD-14.0-RELEASE-i386-bootonly.iso as the only attached device:

a) with efi checked - boots to an EFI interface (startup.nsh) and 
exit(s) into another interface to "Standard English"... "Continue" loops 
back to UEFI shell.  I lack the knowledge about efi to get the FreeBSD 
OS to start.

b) without efi checked - "FATAL: Cound not read from the boot medium! 
System halted".


FYI: My original problem: I built from source 14.0Releng and upgraded 
the 14.0Release without success.  I've also used two other vdi's without 
success.  The upgrade used the git pull from 14.0Releng on a 13.2S 
system as I'm hoping to migrate my fleet of 12.4S systems to 14 and 
figured that 13.2S was a safe build platform (as it also used clang 
16.0.6). I suspect something that I'm doing is at fault.  Unfortunately 
the 6 other 12.4S and one 13.2 VM's are functioning so I doubt its the 
Windows/Virtualbox, which points to my build/install.  Investigating 
further.

I appreciate your advice.

Kind regards, Dewayne.
