This is correct assuming of course that the SATA drives are operating in native mode. However many systems also support SATA in IDE compatibility mode which will appear to the OS as IDE and thus be cXtY[sp]. It is a small point but worth noting none the less.

aac

AAC(4)							   BSD Kernel Interfaces Manual 						    AAC(4)

NAME

     aac -- Adaptec AdvancedRAID Controller driver

SYNOPSIS

     aac* at pci? dev ? function ?
     ld* at aac? unit ?

DESCRIPTION

     The aac driver provides support for the Adaptec AAC family of SCSI and SATA RAID controllers.  These controllers support RAID 0, 1, 5, 10,
     and volume sets.  They have four channels in the add-in version or 1-2 channels in the motherboard integrated version, and are most often
     found rebadged by Dell, Hewlett-Packard or IBM.  Supported controllers include:

     o	 Adaptec AAC-364
     o	 Adaptec SCSI RAID 2120S
     o	 Adaptec SCSI RAID 2200S
     o	 Adaptec SATA RAID 2410SA
     o	 Adaptec SATA RAID 3405
     o	 Adaptec SCSI RAID 5400S
     o	 Dell PERC 2/Si
     o	 Dell PERC 2/QC
     o	 Dell PERC 3/Di
     o	 Dell PERC 3/Si
     o	 Dell PERC 320/DC
     o	 Dell CERC SATA RAID 1.5/6ch
     o	 HP NetRAID 4M
     o	 HP ML110 G2 (Adaptec SATA RAID 2610SA)
     o	 IBM ServeRAID 8k

     Access to RAID containers is available via the ld device driver.  Individual drives cannot be accessed unless they are part of a container or
     volume set, and non-fixed disks cannot be accessed.  Containers can be configured by using the on-board BIOS utility of the card.

DIAGNOSTICS

     The adapter can send status and alert messages asynchronously to the driver.  These messages are printed on the system console.

SEE ALSO

     intro(4), ld(4)

HISTORY

     The aac driver first appeared in NetBSD 1.6, and was based on the FreeBSD driver of the same name.

BUGS

     This driver is not compatible with controllers that have version 1.x firmware.  The firmware version is the same as the kernel version
     printed in the BIOS POST and driver attach messages.
