Thanks.

For the record, SB700 has additional two-port SATA on the ATA 
controller unlike SB600.  These two SATA ports appear as one ATA 
channel and only work in legacy mode -- this mode is so called 
"combined mode" in BIOS configuration.  That means, if you connect 
your DVD drive on one of these ports, it will be running in PATA 
mode, not in SATA mode.  If the combined mode is disabled from BIOS, 
the two SATA ports disappear and it will work exactly like SB600 
single-channel ATA controller.
