I have a brandless industry hm87 motherboard in my hand, in intel's datasheet it supports raid and intel smart response technology, but in this mb's bios, the sata controller only has ide mode and ahci mode, it doesn't have the raid mode, the intel smart response technology require the sata controller work in raid mode, so i contacted the manufacturer, they says i am the frist one asking for a bios update for a decades, and no body use raid in they products, so they refuse my request and here i am.
also the bios chip is 8mb size, i used AFUWINGUIx64 to save the bios, but it only have 4mb, the bios doesn't contain a GUI like those consumer grade motherboards, it already has:
EFI IRST RAID for SATA - 12.5.0.1815
OROM IRST RAID for SATA - 12.5.0.1815
it just missing a raid option in advanced>sata controller>sata mode selection

@xiaox "First one to ask" reply, I doubt.... So are they trying to tell you they don't already have that BIOS made internally, or can't make for you in two seconds? (lame, and lies! )

Please do below, also, if you have the stock BIOS download/package they do provide (if they even provide) for the BIOS you are on now, please include

they reply me if i purchase 500 or more motherboards in one time, they can make a custom bios for me, but i only purchased one, so unless it's broken, no any after-sales service

the bios file is here

i use this guide [Tool Guide] AMI Setup - IFR Extractor AMISetupWriter to track sata controller mode setting, i use it alter 0x1D3, 0X1D4, 0X1D6 to 0x2, and 0x211, 0x212, 0x213, 0x214, 0x215, 0x216 and 0x21a to 0x1, and 0x21b to 0x3, it work for now, the system identify as Intel(R) Chipset SATA/PCIe RST Premium Controller, i installed intel rst driver and intel srt work find now, but in the normal motherboard, when i set to raid mode, it will have a screen ask me press ctrl+i to enter intel raid orom setup, in this motherboard it doesn't appear

@Lost_N_BIOS I tried use amibcp to unlock hidden settings, so now i have 2 "sata mode selection" in the bios i belive the frist one is the 0x1D3 and another one is 0x1D4, and i tested them, the secend sata mode selection witch has ahci and raid both not working, but the frist sata mode selection only has ide and ahci, but i can force set it to 0x3(is the raid mode) using amisetupwriter, and after i use amibcp to unlock the hidden sata mode selection menu, some of cpu settings (maybe more and others) is missing, also my computer already crashed 3 times after flashed the moded bios for now.
