I figured out some stuff... the reason the USB drive no longer boots is because
u-boot is configured to boot in a certain order, and the Linux install is
earlier.
You can do things like:
ls usb 0:1 /
and then the key is efi or eficonfig and move usb earlier than nvme.
That let's the USB drive boot.
I still haven't figured out how to boot the OpenBSD install.
Perhaps it is this:
> => run findfdt
> => load mmc 0:1 ${fdt_addr_r} ${fdtfile}
> => load mmc 0:1 ${kernel_addr_r} efi/boot/bootaa64.efi
> => bootefi ${kernel_addr_r} ${fdt_addr_r}
>The bootloader will then run and try to load sd0a:/bsd off an FFS
This is outide of the Mac area of the documentation.

Subject: booting Mac?
Hi. I have M1Max MacBookPro. I installed the Asahi Linux EFI environment,
then booted install76.img from USB, went through the install seemingly
successfully, installed all sets, relinked kernel, and then the system
won't boot. I mean, I can get to the boot menu and back to MacOS, and
even since instaleed Asahi Linux completely.
But if I boot the EFI option, it doesn't get past the early UBoot.
Nor does the original flash still boot. I even re-dd'ed it in Linux.
It doesn't find its files.
I cannot boot OpenBSD is what I mean.
Any ideas?
Btw, the install is a little unfriendly/unclear. When it says "whole disk"
I'm not sure it is talking about the disk or a partition.
I wasn't sure if I'd learn MacOS,but I managed to get through it.
Thank you,
Jay
