Bios Mods -The Best BIOS Update and Modification Source

I have a few OptiPlex 3020s I am rebuilding and upgrading, and was sad to learn Dell only has AHCI support in the BIOS, but no RAID option.

I am wondering if this is something that can be easily modded and "turned on" in the existing BIOS code, without any major code revisions.

I am looking to do RAID 1 only.

Link to latest BIOS update from Dell, version A19:

The OptiPlex 3020, in all form factors, MiniTower, Small Form Factor, and Micro, use the Intel H81 Chipset.

Any help would be appreciated.

H81 does not support RAID, and I checked the BIOS and the SATA operation option only has Disabled, ATA, or AHCI options (even if manipulated, still no RAID)

Wow, thanks for doing the speedy investigation, I was unaware of the limitation of this chipset.
