Re: [PATCH] PATA support for Intel ICH7 (intel 945G chipset)

["Gaston, Jason D" <jason.d.gaston@intel.com>]

Jan,

DeviceID 0x27c0 is the ICH7 SATA controller DID.  It should not be added
to the PATA IDE piix driver.  It is already supported in the SATA
ata_piix driver.  If you are not seeing the PATA controller DID 0x27df,
then your BIOS is most likely set to combined mode.  Change your BIOS to
SATA enhanced mode.  If your BIOS does not support enhanced mode,
contact your motherboard manufacturer.

Thanks,

Jason
