Multiple hardware devices can be initialized in parallel between vga initialization and option rom initialization. One can set this file to a value of zero to force hardware initialization to run serially. Alternatively, one can set this file to 2 to enable early hardware initialization that runs in parallel with vga, option rom initialization, and the boot menu.

No, it's not expected. If you set 'etc/threads' to 2 then you should
get the boot menu prompt even before the drive finishes spinning up.
If you send a log we can take a look at it.
