Win7+ICH7(no ACHI)+Intel G2SSD support Trim?

[idata]

My MainBoard is EP31 and the south bridge is ICH7 (it doesn't support ACHI and eSATA)

I installed Win7 32bit verstion in Intel 80G G2 SSD, I ran the command and it displayed the value is 0 (means support Trim)

Is it really a "Trim" device now?

The device is, but non AHCI mode not sending Trim to thr drive.

AHCI is the only way.
