Hi,
opensuse tumbleweed:
up to now, i have had no inducement to change my harddrives from legacy boot to uefi boot.
but now, i figured out that the full speed of the graphic will need "csm" off in bios/uefi, to switch on "resizable bar"
still i do not understand what has the amount of data to be transferred to the graphic card has to do with the way bios/uefi is searching for the start sequence of the operating system. maybe i am to stupid. :-((
so now i need a little help:
i have serveral tumbleweed installations, the easiest look like:
Disk /dev/sda: 11721045168s Sector size (logical/physical): 512B/4096B Partition Table: gpt Disk Flags:
Number Start End Size File system Name Flags 1 34s 2047s 2014s grub bios_grub 2 2048s 11721041919s 11721039872s ext4 Linux filesystem legacy_boot 11721041920s 11721045134s 3215s Free Space
they are booting fine with csm on.
i like to convert them to uefi boot, have read here:
Don't bother. I don't see the advantage. Enable UEFI mode in the "bios config" if you like, but don't bother migrating the disks, if they work in that mode. If you ever install again the system fresh, then let the installer do it. -- Cheers / Saludos, Carlos E. R. (from 15.5 x86_64 at Telcontar)
