1 - In case we use an external GPU, the IGD is disabled at arly_init.c (line #686). (BTW: line +949 should be commented)
2 - there some desktop's version that do not have IGD at all.
3 - at function "sdram_power_management", we set integrated_graphics = 1 and use it for test in raminit.c line #2305 .... this do not make sense.
