AHCI Bios not installed
I am having issues where I turn on AHCI in the bios, but when I am booting I am informed that "AHCI Bios is not installed" Everything still seems to work and I can boot into Windows fine, and I even seem to be accesing the drive with AHCI in windows, but I amexperimenting with different OS's and they can't see my AHCI drives. I just updated Bios from A06 to A07 and reset the board via jumper and still no change, any ideas?

This may be normal. In your 690, you've no doubt noticed that you have two sets of "SATA" connectors - one group that's marked HDD and one group that's marked SATA.
The HDD group are connected to the LSI combination SAS/SATA controller on the motherboard (it's the chip with the metal circle on top, for whatever that's worth) - you should be plugging your hard drives into these connectors. The SATA group are connected to the Intel ESB2 south-bridge chip (it's hidden under a wide, flat silver metal heat sink). You should connect your CD, DVD, etc drives to these three connectors.
If you've done that, then you'll get the message you describe as a side effect. The Intel ESB2 software loads, looks for hard drives, but finds none (only CD drives and the like). Failing to find a hard drive - which is OK - it then posts that message to tell you that it didn't bother to install the ACHI "driver" portion of the BIOS.
Poorly worded, I think; in fact that message is completely unnecessary. But if I'm on the right track it's nothing to worry about.
You can test for this by temporarily plugging a hard drive into one of the three SATA ports. If the message goes away, we've found the culprit.
