No. It was there with 0099.
It may have always been there but wasn't noticeable. I normally plug my main hard drive into SATA port 0. I assume most people do it that way. If there is no drive in a Marvell port, it seems the BIOS will boot from port 0 and usually that is what is desired.
I also have used BIOS version 0070. The Marvell SATA ports don't work right with that BIOS version, so I didn't have a drive plugged in there.
In other words, the first time I was able to use the Marvell ports was BIOS version 0099, and that is when I noticed that it booted from a Marvell connected drive, unless I hit t F10.
