My Asus Motherboard does NOT have a AHCI setting in the bios...Running XP Pro 32bit right now but have Windows 7 Pro ready to install...Please don't tell me I have to get a new MB...I love how fast SSD works in Windows XP Pro even in IDE...Do I have to have AHCI mode for TRIM to work in W7 Pro?...Thanks to any-one who can help...
 
"What if my system doesn’t support AHCI?

If you have a system that does not support AHCI, or if you fail to enable it properly, your system will run in “IDE emulation” mode, a kind of compatibility mode that mimics the functionality of the older “Integrated Drive Electronics” ATA interface. While your SSD will not display its full performance potential or be able to take advantage of all of the latest SATA functionality, it will still be able to function on your system. "

More info from http://en.wikipedia.org/wiki/Trim_(computing)

You can see : Windows 7 only supports trim for ordinary (SATA) drives and does not support this command for Storport PCI-Express SSDs that are a different type of device, even if the device itself would accept the command.[39] It is confirmed that with native Microsoft drivers the Trim command works in AHCI and legacy IDE / ATA Mode.[40] Windows 8 and later Windows operating systems support trim for PCI Express SSDs based on NVMe, and the unmap command which is a full analog of the trim command from Serial ATA for devices that use the SCSI driver stack.

So SSD works on winxp but no TRIM, and works on win7 with TRIM, but like alexoiu said the SSD does not get the full performance potential.

* I forgot one thing, your MB has only ICH7 ( not the ICH7R, R means raid support) so you can't use the raid mode either.
