In OpenBSD 6.8, loongson was converted to use MI installboot.
For Gdium, INSTALL.loongson tells you this:
To boot the bsd kernel on the G-Key by default, assuming it has been
copied to /boot/bsd on the first ext3 partition, and the bootloader
has been copied to /boot/boot on the same filesystem, the settings
are:
PMON> set al /dev/fs/ext2@usbg0/boot/boot
PMON> set rd /dev/fs/ext2@usbg0/boot/bsd
Earlier OpenBSD versions would copy the kernel for you on that
partition. OpenBSD 6.8 doesn't do this anymore, so it won't
boot on Gdium unless you manually copy the kernel to the ext2fs
partition.
Indeed, distrib/loongson/ramdisk/install.md had this:
# Use cat below to avoid holes created by cp(1)
if mount -t ext2fs /dev/${_disk}i /mnt2 &&
mkdir -p /mnt2/boot &&
cat /mnt/usr/mdec/boot > /mnt2/boot/boot &&
{ [[ $(sysctl -n hw.product) != Gdium ]] ||
cp /mnt/bsd /mnt2/boot/bsd; }; then
umount /mnt2
return
fi
but loongson_installboot.c doesn't copy the kernel anymore,
so what worked "out the box" on Gdium before now doesn't.
I don't know if the way the you want to fix this is to add
the missing kernel copy to loongson_installboot.c, or if
INSTALL.loongson should just be modified so that the "you
must copy the kernel manually" requirement becomes a bit more
explicit, now that this is mandatory on Gdium.
