Re: SuperMicro X8DTL-6F motherboard, Intel ICH10 SATA, SiI3726 SATA port multiplier

[Todd Pfaff <pfaff@xxxxxxxxxxxxxxxxx>]

Despite the appearance of partial success in my syslog messages below (ie.
PMP appeared to sorta kinda be trying to work, almost), I've since read
some more that leads me to believe that Intel ICH10 does not support PMP.
And Intel authoritatively says so here:

  http://www.intel.com/Assets/PDF/datasheet/319973.pdf

    page 538, section 14.4.1.1, Bit 17

    Supports Port Multiplier (PMS) - R/WO.  ICH10 does not support port
    multiplier.
    NOTE: This bit must be set to 0.  Port multiplier is not supported by
    ICH10.

So, I give up.  I edited the wiki page here accordingly since it was
wrong:
