W7 detect my SSD as a SCSI disk device. How to change it to ATA device?

[idata]

My configuration:

OS: W7 x64 Ult

MB: Gigabyte EX58-UD3R

SSD X25-M 80GB G2 plugged on the GSATA 2 connector of MB

What I tried:

1. In bios setup: switch "Diseable" in AHCI mode => boot stop at DMI detection
2. On motherboard move SSD from GSata 2 (GigabyteSATA) connector to Sata 2 connector (ICHR10) => Message: "bootmgr is missing
3. To see what Crystaldiskinfo could say about my SSD => CrystaldiskInfo don't list my SSD!

the problem of restarting after check AHCI in bios setup is caused by a Windows installation with IDE driver instead of AHCI driver.

This only happens, if you change the BIOS settings of the SATA ports from "IDE" to "AHCI" after the Win7 installation.

If you do it before starting the OS installation, the in-box MS AHCI driver will automaticly be used by Windows 7 (no risk of any boot problems and no manual registry manipulation required).

Yes, exaclty. Thank you Fernando for having translated more clearly what I meant. My english is very rough...
