I haven't looked in depth yet, but it's a bit more. the loader switches to amd64 and sets preliminary page translation

Please try the btx loader in /boot/loader, which I believe to be

Ah, just noticed I replied to this before subscribing, so the copy to
the list bounced.
Let's try again.

The BTX loader starts, yes - but the reason I'm using GRUB2 in the
first place is to skip it,
since it doesn't seem to support logical partitions.


Oh, thanks for the information. The 32-bit bsd kernel is basically an
elf image that needs a little address translation:

physical address = virtual address & 0xFFFFFF

I think the principle can be applied to 64-bit kernel as well, it
shouldn't be difficult to add support for it.
