There is no need to install efibootmgr I've posted. Just want to check the
content of the boot entry.

The short device path is convenient in some cases. For example, moving hdd from
SATA1 to SATA2 won't break the boot entry since the UUID doesn't change. A boot
entry with a full device path is restricted to the specific bus.

It seems the firmware doesn't like the short device path :-(

It just means SATA1 is wired to PCI bus and is common in x86 systems.
