in the SATA kconfig menu, the help message from  
Intel PIIX/ICH SATA support says:

 CONFIG_SCSI_ATA_PIIX:

This option enables support for ICH5 Serial ATA.
 If PATA support was enabled previously, this enables
 support for select Intel PIIX/ICH PATA host controllers.

anyone care to clarify if this mean that having enabled:

CONFIG_IDE=y
CONFIG_BLK_DEV_IDE=y

i can use the PATA ports on a ICH5 controller through libata ?
if not, which is exactly the meaning of "If PATA support was enabled
previously" on this message ?

thanks.

-SL.

I agree it is quite confusing wording.  Probably should remove all 
reference to PATA in the CONFIG_SCSI_ATA_PIIX Kconfig entry.

The comment is referring to the somewhat-hidden fact that if you define 
ATA_ENABLE_PATA in include/linux/libata.h, then libata will support your 
Intel PIIX PATA controllers, in addition to the Intel PIIX SATA controllers.

However, since ATAPI support isn't yet stable, this is of limited 
usefulness.
