I'm testing on a Macbook 2015. I've tried from both an external USB drive as well as my own EFI partition on the laptop. It only has the EFI partition on the internal disk, created by OSX running on a USB flash drive.

I'm using the snapshot from ftp.openbsd.org/pub/OpenBSD/snapshots/amd64, both the bootx and bsd.sd. Ihad trouble objcopy as noted, so I was going for a fresh install when I found the snapshot files.

When booted from external USB, the boot strings find hd0 and hd1--which maps logically to me to the USB drive and internal drive. The default drive is fd0a. fd0a doesn't seem to function with ls. I'm having a similar problem with the drives. I'm not sure what to call them. hd0, sd0, wd0, hd0a....?

The same holds true for a boot using only the internal disk. Only hd0 found on boot, defaults to fd0a, can't find bsd to push forward.

Anything I can do, i will try.

So I'm trying to build the efi bootloader on OpenBSD 5.7 but I'm hitting this error

===> bootx64
objcopy -j .text -j .sdata -j .data -j .dynamic -j .dynsym -j .rel  -j .rel.* -j .rela -j .rela.* -j .reloc  --target=efi-app-x86_64 BOOTX64.so BOOTX64.EFI
objcopy: BOOTX64.so: Invalid bfd target
*** Error 1 in bootx64 (../Makefile.common:63 'BOOTX64.EFI')
*** Error 1 in /usr/src/openbsd-uefi/src/sys/arch/amd64/stand/efiboot (<bsd.subdir.mk>:48 'all')

Indeed objcopy doesn't support this target

$ objcopy -h
[...]
objcopy: supported targets: elf64-x86-64 elf32-i386 coff-i386 efi-app-ia32 elf64-little elf64-big elf32-little elf32-big srec symbolsrec tekhex binary ihex netbsd-core

How do you get this to build? Have the targets been changed in OpenBSD-current?
I've been trying to build binutils with this target manually but I haven't been successful.
