Ups, i deleted that part. My point was that we have wait for the manufacturers
to provide firmware. This does happen out of our control anyway. No matter if
uefi or csm - in both cases we have to rely to the manufacturer. My bios does
have a flashtool inclueded but i have to format an usb storage device to fat32
and copy the bios to it. I don't see much difference if i dd an image or copy
the file. I see the efi partition as somthing like a permanent usb stick.

Same task, we need to kickstart the boot sequence. The differnce between uefi
and csm is the storage location of the whatever starting software.

My last one extracted a windows disk imager and copied the image to floppy.
Those are self-extraction compressed exes sometimes that can be unzipped or
unarj'd to get the real image.

 GK> Which software are you looking for?

None. It looked like ee. uefi adds a layer of complexity. If i want to use
uefi like a rescue system i can't simply use my known tools from my disk. I
think i will stick on my rescue stick in case of trouble because the tools i'm
used to are available.
