Dear SeaBIOS folks,
On the ASRock E350M1 with coreboot and SeaBIOS, setting the runtime config
option `threads` to 2, I am unable to press the boot menu key (ESC). 
By default, SeaBIOS will parallelize hardware
initialization during bootup to reduce boot time. 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.
My rotating hard drive is pretty slow, and SeaBIOS is waiting for that.
Not adding `etc/threads` to CBFS, pressing the key works, and the boot menu
Is that the expected behavior?
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.
