Hi Eric,

I was under the impression that modern UEFI based systems were dropping 
all legacy compatibility,
officially only supporting Windows 7 and recent Linux systems. Seems 
like I was wrong there.
I hope any current harddisks (below 2TB) will remain using MBR under 
UEFI instead of GPT being required.

Ah so UEFI with a compatibility legacy BIOS under it? nice, however not 
very publicly advertised.

I was hoping for a 4MB flash with small coreboot/seabios thus lots of 
space for FreeDOS :)
For network installs of modern operating systems I guess a scripted PXE 
environment might help (www.ipxe.org for example)
Not much info to found about "install your OS from same disk you want to 
install it to".
