HD4400 problem on Haswell ULT htpc

[daddyofsky]

I installed El Capitan on my htpc (made by a chinese company, not major brand).

Intel Core i5 4200U / HD4400 (device id : 0x0a16) / Haskell ULT / CRESCENTBAY

I followed RehabMan's Guild.
https://www.tonymacx86.com/threads/fix-hd4200-hd4400-hd4600-hd5600-on-10-11.175797

The problem is,
If I set confing.plist/Graphics/InjectIntel=true it do not boot up.
If set InjectIntel=true it boot up, but device id not changed to 0x0412.
Already tried change ig-platform-id to 0x0d220003, 0x0a260006, and so on but same result.



I attach CPU-Z report and some stuff.
Please help me.

Make sure your monitor is connected with HDMI, DP, or DVI-D.
Make sure BIOS is set correctly (64mb IGPU prealloc).

Monitor is already connected with HDMI.
Bios is set as below.
(It seems that bios is available to set low level settings. There are more settings than normal pc)

Those settings (DVMT-prealloc) look correct.
Also, make sure VT-d is disabled.
Correct ig-platform-id for Haswell desktop is 0x0d220003. It is also the default when unspecified.
