Asus x71sl ahci request support

[Nicetry]

Hi!
I have a laptop Asus x71sl and after years my hd goes broke, i bought one new, a ssd OCZ but after upgraded it and the official motherboard asus firmware, i still can't enable AHCI support.
Really sorry i'm a real noob about it, and i really don't know if it's possible to do that...
Here my spec:

BIOS Date 11/05/2008
BIOS Name American Megatrend Inc.

Model X71SL

Motherboard Manufacturer PEGATRON CORPORATION

Thanks in advance for any reply!
