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. GK>>> In the MBR-days you would have needed to have a MSDOS-system on GK>>> the USB stick in addition KR>> Why DOS?

Same task, we need to kickstart the boot sequence. The differnce between uefi and csm is the storage location of the whatever starting software. GK> Updating usually involves some kind of Windows 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. KR>> I'v seen an EFI editor which my bios doesn't have.

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.
