[ale] Linux on UEFI mother boards

[Michael Trausch]

Yes, nearly all UEFI systems provide a BIOS emulation. That said if you need a BIOS emulation and a given UEFI system doesn't have one, you can always use a free BIOS.

As far as network booting... UEFI does network booting differently from BIOS systems. AFAIK the only UEFI systems that offer PXE also offer a real or emulated BIOS, as that is required. You can implement PXE as a UEFI application if you don't follow the local (system to option ROM) spec (e.g. Purely in software with your own drivers). Don't know why you would; just get an IP and pull down a UEFI kernel image and go. :) the prebiotic environment is really nice and it is pretty easy to script, as well.
