Hi all...
I have read that modern nVidia SATA's are AHCI. But several distros I have
tried use the sata-nv module for that chipset controller (MCP55).
Is this correct or should I use standard ahci ? Anyways, it looks that the
kernel/modprobe settings use this, can I change it via kernel cmdline
or modprobe.conf, and force the system to try ahci module ?
By BIOS has no kind of setting to put the controlled in AHCI vs SATA mode...
Playing with alias pci:v000010DEd0000037Fsv*sd*bc*sc*i* ?

Your hardware doesn't claim to be an AHCI device, so the sata_nv driver
is probably correct.

Only ones more modern than that (MCP65 and later) are AHCI, MCP55 still
uses sata_nv.
