Support 32 bit UEFI #209

Open rmguy opened 6 years ago

rmguy commented 6 years ago

I currently have a BayTrail device with a 32 bit UEFI bootloader and a x64 processor. I was wondering if you could somehow publish an iso image with a 32 bit UEFI file as well? For reference, an example of an OS that does this is Subgraph (https://subgraph.com/sgos-handbook/sgos_handbook.shtml#installing-subgraph-os).

NB: I actually do have a 64 bit processor, it's just my bootloader that's 32 bit.

Can you use BIOS?

rmguy commented 6 years ago

My bootloader is a little strange, it doesn't seem to have (expose?) that Legacy/CSM mode toggle. I can try digging around a little harder. Assuming I find it, are these roughly the steps to preparing the usb?

Mount the USB
Format it to fat32 (mkfs.vfat)
Put an MBR partition on it (gparted)
Set the "boot" flag (gparted)
Mount the iso
Copy files using rsync

Or is there an easier way to do this on linux? Or would you recommend just installing something like Rufus on a Windows machine?

@rmguy there are a number of tools and methods to create a bootable disk/usb. In Pop!_OS 18.04, Popsicle (USB Flasher) is recommended which will write an iso image to any number of flash drives you give it. System76 also has instructions for using Etcher.io: https://support.system76.com/articles/live-disk/

These tools will take care of setting boot flags and writing the .iso to the drive.

I tried etcher! it didn't work. Or at least, it didn't seem very configurable. I think it generated a hybrid ISO, and my ghetto BayTrail bootloader didn't detect the USB. Maybe I'll give popsicle a shot.

Fyi Fedora also supports 32bit UEFI mode for their amd64 isos, so it's so tempting to just go with that, even though i really want to try out pop :)

A bit late, but I would also like to see 32 bit UEFI support! I like popos and it would be a great distro for devices such as low-power 2-in-1 laptops that only come with 32 bit UEFI and no legacy/BIOS option.
