Oh, so it appears that package built on x86_64 does not include pre-built grub.efi. And there are no (published) 32 bit packages for Leap. How weird ...

Scratch it. It is not, I mixed something up. Well, this is one of problems I told you about from the very beginning - supporting 32 bit EFI on 64 bit OS is far more involved than just providing installation DVD image.

right now, it's only openSUSE don't supporting it

So you should be able to 32 bit packages from OBS using osc. Otherwise you can get *any* package, e.g. from Tumbleweed - at the end it does not matter, you need single file /usr/lib/grub2/i386-efi/grub.efi.

no, there is no uefi 32 bits Tumbleweed AFAIK did you get a look at the link https://github.com/jfwells/linux-asus-t100ta/tree/master/boot it's not a big deal to compile is if there is no distro-specific option in this page thanks jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

yes there is one, but I presume it's a 64 bits one And there are no (published) 32 bit packages for

Leap was said to be only 64 bits, so it's not surprising. I just try to make it bootable from 32 bits uefi, to be installed then as 64 bits (works for debian)

Well, if you want to use exactly the same version as in Leap,

I just want to install Leap :-) you

and only *boot* support is needed, install can follow as 64 bits.

I think system would break if you updated the grub2 package, without change the LOADER_TYPE to 'none', it will reinstall bootloader which defaults to x86_64.

my IT WORKS TW891 is only 129€ for 1280x800 screen, 32Gb ssd and 2Gb ram.

of course, supporting a tablet is not that easy, not all works natively, but I don't ask for full support, not even to have it on mainstream Leap, but If I could build a Leap network install on Studio to support these machines, it could be a significant step on. Main stream support is probably not that important, because as price drop and memory get bigger, the need for 32 bits should hopefully vanish :-)

Ok. thanks, but I still think full support because the system has to be useful for update and TW did that quite oftenly. Mind to open a fate? then we can sum up more things there, bug may not be ideal for people evalutes efforts. Thanks, Michael

not with uefi. uefi bootloader is choosen by the firmware, not by the OS. If you choose to boot from, say "my32bits.efi" the computer will always boot this.

of course this "uefi boot" is only a priority in nvram, but yast/gru should not change this - add an entry, yes, but not change the default

It won't change the default or the boot order, the potential problem here is that grub2-install will try to cleanup boot entries created by the same distributor with new one. That is you still have to fiddle with distributor manually in YaST or grub settings to get around the problem.

I was not thinking of TW, but the more the better, if this do not delay the result excessively :-)

there is already one

Sorry, I lose tracking of that one. I will try to sum up and put my work toward it. Thanks, Michael

Well, I tried to draw attention and discuss it couple of years ago, but RPM won't allow ELF executable in noarch package and everyone continued to tell me that they cannot go into noarch because they are ELF executable ...

I will get a new IT Works this afternoon, and may be able to continue testing :-)

some details here: https://bugzilla.opensuse.org/show_bug.cgi?id=963496 in summary, I succeed to boot with openSUSE Leap using Tumbleweed 32 bits grub-efi rpm. I have to build myself a EFI 32 bits usb stick, Debian one do not read btrfs (and I installed Leap all as defaults) and my computer is picky: needs the EFI partition to be the first one of the stick, when the standard do not ask for this. I had successfully installed Leap with the help of Debian, using two usb stick (one Debian, the other Leap). Then I could boot with my own usb stick 32 bits EFI TW, that done, from Leap, I could add the 32 bits grub.efi and boot without usb stick. However I was obliged to go to windows and use easyefi to register to go on. Not sure it was really mandatory, but it like this I could do. I still have to write somewhere a grub.cfg to automate the process. jdd NB: Leap works, but is not fully functional, more later -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Well, grub2-mkconfig is still there and will produce exactly the same configuration.

certainly not. It's Leap, that don't even know than grub-i386-efi exists. May be sometime in the future, but not now (default kde install)

But you will also need to manually run grub2-install --target i386-efi if grub2 is updated. Btw, it should also take care of NVRAM entries, at least if Leap has efibootmgr.

this may the future I speak of :-). But for now I only tried to boot an unbootable system... and finally it works. efi boot partition have an EFI folder. In it you can have any folder you want (and the partition size accommodate). For example "windows", "opensuse" (the official openSUSE folder), and, for me, "32". in these folders are the "efi" binaries that do the actual boot, for me grub.efi. You can also add a grub.cfg file with the necessary config right there, alongside with grub.efi and this is the file that will be used. Of course, for openSUSE it's an alien OS, so untouched. To boot, you have to register this on nvram, but there is a default nvram entry for usb device that should but don't on my stick, I have to understand why. and Leap crashed, apparently when trying to hibernate...

Not what?

It's Leap, that don't even know than grub-i386-efi exists.

Grub-mkconfig creates configuration that is platform agnostic (with notable exception of secure boot).

of course not. I just reread the man page, grub2-mkconfig do not ask for the grub version to use. so it gives only one file, the one used by Leap to boot and this one do not boot with 32 bits grub.efi (tested). the grub.cfg next to the efi binay in opensuse folder simply link to grub.cfg in /boot. as far as I know, one can't have two config files in "opensuse". to boot my itworks, I had to wrote the 32bits grub.efi in an other folder (I named it "32"), and add a grub.cfg with essentially ........ set btrfs_relative_path="yes" search --fs-uuid --set=root 28efb6d2-1287-4f29-b38b-b383b89d6568 set timeout=10 menuentry "Jean-Daniel's openSUSE Leap 42.1 nomodeset" { linux /boot/vmlinuz nomodeset initrd /boot/initrd } .............. (plus several entries for various tests) The first line come from the official openSUSE grub.cfg (partition UID) copying the official grub.cfg in the same place as mine gives unbootable result (the computer skip ti and boots windows). several hours of tests :-( jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
