Yeah, it's the same link, here it is
again as I posted this on the wrong thread this morning, must have been tired at that time!
Anyway the issue seems to be specifically with Asus P5 mobos due to Asus not injecting Intel OROM updates so the AHCI mode doesn't work correctly with the SSDs, the guy in that thread was determined to make his SSD work in AHCI mode but for some reason not too determined to use the BIOS update fix suggested on many occasions, even by those who had successfully tried it themselves.
