Yes, link - http://lkml.org/lkml/2007/10/8/93 add the AHCI legacy support to sata_nv when IDE/RAID mode been set in SBIOS and Device IDs are not in ahci.c at this moment. To do so, when a new chipset come out and DIDs haven't been submited to LKML,user still can use ahci driver to handle it when setting AHCI mode in BIOS, using sata_nv when setting RAID/IDE in BIOS. For example, ahci driver in Fedora 7 doesn't include the DIDs of MCP78, so if you set the IDE/RAID mode in BIOS, os installation onto SATA drive will fail. But if Fedora 7 include this patch, installation will be successful. 2007/10/19, Jeff Garzik <jeff@xxxxxxxxxx>: > peer chen wrote: > > Ok,I agree to use AHCI driver for our AHCI controllers no matter their > > class codes are IDE/RAID/AHCI.
