Hello Kevin,
Thanks a lot. Is this native 16-bit AHCI support that doesn't rely on an option rom?

That is great to hear. Some HP notebooks have this capability, but I know of no others. This setup should allow cutting seconds from Windows boot time because Windows spends lots of time on IDE drives that are not installed. If all IDE devices are disabled and only AHCI visible, Windows can boot a lot faster.
I made an initial test using coreboot+seabios on an AMD RS780/SB700 system. So far it is not detecting the drives. But this test required hacking in code to disable the SB700 IDE device and switch the SATA device from IDE mode to AHCI mode. I have not yet checked to see if that code is even working correctly. I will continue debugging this in a day or two.
Thanks, Scott
