Hello,

A while back I'm sure I saw a thread somewhere that detailed how edit the supported hardware of Intel RAID Option ROM's... which I now can't find despite a day of searching and I'm not even sure which forum it was on :( As far as I can recall there was some information on an internal compatibility table/list of sorts inside the option ROM and I vaguely recall seeing a screenshot with an option ROM open in a hex editor demonstrating the point.

I think the point of the thread was overcoming an "Unsupported_Hardware" error message.

Can anyone help track this information down?

Thanks for the reply (Great site BTW), I think I've seen that before but its not quite what I had my head :)

As I'm sure you know ICH7R (27C3 - no alternate ID) is still supported by Intel RST v11.2.0.1006 but I'm wondering if it would also be possible to update the option ROM for the ICH7R to support RAID0 TRIM.

The board has MSM v5.1.2.1002 which I have tried to update to "Intel-MSM_RAID-ROM_v8.5.0.1030_TRIM-mod-acc-CPL0" - Based an a post I saw I had to modify a part of this from "86 80 22 28" to "86 80 C3 27" and redo the checksum however this throws an unsupported hardware error on boot up. So at the moment I'm looking at trying to alter v8.5.0.1030 to support ICH7R or maybe if possible modify v5.1.2.1002 to support RAID0 TRIM.

I saw a list on Wikipedia (not sure if accurate) that notes the last option ROM to support ICH7R was v11.7.0 but every version below and including v11.7.0 I've tried has failed, I have not yet gotten a ROM above v5.1.2.1002 to work at all.

I'm not worried about bricking the board, its got a removable BIOS chip and I've got an external programmer so I'll keep trying :)

Thanks! File attached.

I'll see if v8.0.0.1039 is one of the ones I tried. - EDIT, I just tried v8.0.0.1039 and it shows "Hardware_Unsupported".

@ Svortex:

Although the attached .zip archive was corrupt (unexpected end), I was able to open the .bin file with HxD.
Result: It is impossible to modify this very old Intel RAID ROM according CPL0's method, because the byte, which has to be changed, belongs to the absolutely needed HardwareIDs of the Intel SATA RAID Controller.

Did you modify the ROM file? If yes, how?

I wanted to check the file you had modified and not the source file.

No unsupported hardware error this time but it locked the system up after the Intel copyright notice.

Edit - I've just found a later version that seems to work - v5.7.0.1011, could this be modified for RAID0 TRIM? I'm going to keep trying various versions to see which is the latest I can get running with ICH7R just in case I missed anything the first time around.
