Hi, Yesterday hetzner.com came out with arm64 cloud instances, I tried one out. Here is what I found. The images they give you a choice of does not include OpenBSD, so I had to get a ubuntu OS. That's fine the EFI partition was already mounted. Through trialing this I found the best way of getting the OpenBSD loader to boot was the following way:
1. place miniroot73.img on the EFI partition root (/boot/efi/) 2. reboot 3. press escape to get to the BIOS, there is 3 options one is a configuration option under 1, enter it. I'm working off memory here I didn't save anything so take it with a grain of salt on exactness. In this option is an option to create a RAM drive from a file, go there and enter the miniroot73.img (45MB). The down arrows didn't work in this BIOS so it was great that it wrapped around going up. 4. next go back into the main bios screen by pressing escape. There is option 3 for boot options, enter it. There is a boot from file option enter it. Select the RAM drive and manouver your way to the bootaa64.efi file. Press enter. 5. OpenBSD loader now loads. ls displays bsd and bsd.rd, the console is on comcons0 or something like that. Switching to fb0 works too. Then when pressing boot a blank screen happens. Waiting a while no prompts and I didn't try to blind type anything. Doing this again with fb0 doesn't work either. 6. Full stop, I didn't get further. I then deleted my instance as ubuntu is not good enough for me. I guess we'll have to wait until the pros get to it. Thanks! Best Regards, -peter
