My memory might be off, but I think this is a problem with nvidia
chipset AHCI not being fully supported in DragonFly. I have an ASUS
atom/ion motherboard which fails installation with AHCI enabled in the
bios. When I googled around I found an OpenBSD user had a similar
issue and reporting they just added a pci-id for it, (something like
MCP79 AHCI wasn't there originally) to fix their problem... I haven't
had time to dig further and see if the same type of hack would work
under DragonFly.<p></p></body></html>
