Thanks for answers. Still a little unclear on your second to last comment "When I reset, it recognizes as AHCI" Whan you reset what, and what recognizes as AHCI? If you mean when you reset BIOS it's AHCI, that would be a given, since AHCI is the default option for that setting

Sounds like this system has IDE functionality removed from BIOS, or chipset disabled etc. You can try this BIOS, but I assume outcome will be same.
Once BIOS flashed in, boot to BIOS, load optimized and do not change anything related to IDE/AHCI, reboot back to BIOS, make any other changes you want (Still not touching IDE setting), then try installing OS and see if you get IDE possible or not.
This BIOS has EVERYTHING set to IDE by default, setup, AMITSE/SetupData, NVRAM and hidden/shadow NVRAM backup too.

Read carefully >> Flash this time ONLY, using this command >> FPTw.exe -rewrite -bios -f IDEALL.bin
Be 100% sure you don't leave out the -bios flag in that command!

And don't use -rewrite other times when using FPT, this is special circumstance, so BIOS region is 100% erased before writing, that way old NVRAM backup volume that doesn't get dumped with FPT Dump is removed

I got the raid mode by setup_var. setup_var 0x201 0x2
---------------
But I cannot get IDE mode

If flashing above BIOS at post #31 exactly as I described does not enable IDE mode after flashing and loading optimized defaults, then this board cannot do IDE mode (may be missing hardware, or chipset functionality etc)
RAID/AHCI is very different than IDE. Some systems require add-on IDE controllers other than what's offered by the chipset/PCH, this may be one and would be the reason this was hidden in the BIOS by default.
This is due to Intel phasing out older tech features, IDE is one of those things they are doing away with, along with BIOS as well.

@XPLives & @Fernando may be able to expand more on this for you, 9th series PCH/CPU (Broadwell - i7-5500U, i5-5200U, i3-5010U) being latest Gen would be right in line with that kind of phasing out of older tech.

@Fernando - For your info in case you didn't read back. The original BIOS here only offered AHCI as storage function, I enabled IDE/AHCI/RAID option.
Additionally at post #31 above, I made him BIOS with IDE set as default in all possible areas, settings storage and NVRAM etc, so it would have been forced to 100% IDE function only provided no BIOS settings change by user and IDE function was possible by hardware
I think hardware does not support IDE function in this case
