100PIER is right. The Intel RST drivers v12.5,0.1066, which are still officially offered by Intel, definitively do not support the TRIM in RAID0 feature for Intel 7-Series Chipset systems.

In the other hand, the option ROM is provided directly by your computer manufacturer, not Intel. In such case, if you have issues with the option ROM in your computer you need to contact your computer/motherboard manufacturer directly for assistance.
It is not the mainboard manufacturer, but just Intel, which is exclusively responsable for the function of their drivers and OROM modules. The mainboard manufacturers have nothing to do with the development and the release of the AHCI/RAID Drivers and PCI OROM modules, which are needed to get the Intel SATA Controllers properly working.
