How to enable TRIM for SSDs in RAID-0 on Intel 6-series (P67, Z68) chipsets

Few months back Intel announced that they were finally bringing TRIM support for SSDs in RAID setups (specifically RAID-0). But that support came with one limitation. Only the 7-series boards were supported. That means Z77, H77 and so on. People with old P67, Z68 boards were left behind. 

Technically, there was no reason why 6-series boards could not support it, but they had the old RAID ROM (firmware) which were not supported. Of course the manufacturers could release BIOS (UEFI) updates with the new RAID ROM, but we all know that would never happen. They want to sell their new boards. Why support the last generation? 

Even though the RAID ROM is bundled with the BIOS (UEFI) files, it is a separate thing. You can hack the BIOS file and modify the RAID ROM potion of it with the new ROM.

Some guy at Overclock.net forums has posted such modified BIOS files for Gigabyte, ASRock, MSI and Asus boards (click on the link to access them).  If you are using SSDs in RAID-0, give it a shot. If your particular board is not listed, you can upload the BIOS file and ask him to modify it. 

Here's the link to the forum thread. LINK

You of course will have to install the correct Intel Rapid Storage Technology drivers to get it to work. Everything you need to know is posted in the first post of the above thread.

I don't really have a reason to update to the new RAID ROM because I have given up on RAID-0. But I would just update it for the hell of it - when I get back home. That's me. ;)
