No, it covers only the one I can personally test and confirm to require
this quirk, beyond my own ASRock Q1900DC-ITX[1], there are at least:

Celeron J1800:
 - ASRock D1800B-ITX,
 - ASRock D1800M,

Celeron J1900:
 - ASRock Q1900B-ITX,
 - ASRock Q1900-ITX,
 - ASRock Q1900TM-ITX,
 - ASRock Q1900M Pro3,
 - ASRock Q1900M,

Pentium J2900:
 - ASRock Q2900M,
 - ASRock Q2900-ITX,

All very similar boards, but their BIOS state might differ.

However I've never had access to any of those and could only do an
educated guess about their DMI identification[2]. While researching my
problem on the web, it seems that Baytrail-D boards from several vendors 
might be affected (e.g. Gigabyte). Sometimes apparently fixed by later 
BIOS updates, but I can only confirm the problem and workaround for my 
own ASRock Q1900DC-ITX mainboard (where all published BIOS versions are

	but I don't have direct access to that board and can't
	check if it is also affected by this problem.
