Marvell® PCIe SATA 6Gb/s controller

Hi all, I have the Asus P8Z68-V Pro and it has two Marvell® PCIe SATA 6Gb/s controllers which are navey blue. I noticed that they don't appear in the bios and you can't boot from them. but they do work once you get into windows. I called Asus support and they confirmed this. Is this the case for all boards that have these sata ports?

Hi Had a Crosshair IV extreme and was the same. I connected the DVD rom to it and installed OS from that port. Also my Samsung HDD's were not compatible with the AMD chipsed and used them for a while on those two ports before upgrading FW. I think they were designed for optic drives only to not slow down the AHCI or RAID on the AMD chipset when a CDrom is connected also so they provided two sepparate connectors. Hope that explains it

Try move the optical onto it. It should work. I never raised the question to be honest. I have too many sata ports and too less devices to fill them up anyway . Maybe the controller has the external sata hoocked onto it and the other two ports can be used for the same. From a SATA point of view shouldnt mater if its a HDD or optical they are treated the same

I've never heard of a board that won't let you boot from the Marvell controller. Weird. Maybe only the RAID-capable Marvell controllers are bootable?

In any case, I recommend that you don't use the Marvell navy blue SATA3 ports unless you have to. The Intel gray SATA3 ports are way faster, so use those first.

I am using this motherboard, and yes, the manual does state that these ports don't support ATAPI devices like optical drives. Sounds like you proved that!

These ports do show when the BIOS boots - I usually see a message flash by telling me that I don't have any drives plugged in. I should really disable the controller, although I might use it for eSATA.

I would use the Intel ports in preference, reserving the Marvel ports for overflow. I won't need them in a hurry, because this build only has a Vertex 3 240GB on one of the Intel 6Gbps ports, and a DVD writer on one of the Intel 3Gbps ports. Plenty of room for expansion

Compulsive doesn't see them in the BIOS with the rest of the drives. During the boot process though, it should flash up a message that says "No drives detected" or something like that (assuming you have no drives attached to the navy blue ports).

I would check for the latest BIOS revision. And yes i agree the marvel controller cannot be set from anywhere. Its quite useless unless you have something like 8 SATA devices connected which is quite rare for home use. The marvel services also the 2 eSata ports and far as i know the two blue ones on the mobo are hot plug-able too i.e. connect them to removable bay or case eSata ports(anyway most are these days ) . Please double check this info do.

here's an update: first of all, the Asus call center is the most horrible call center on the face of the earth. everytime I call, I choose 1 for motherboards. then I get put on hold to wait for a tech. then I hear the ringing sound as if a tech is coming on the line. then I hear nothing for about 20 seconds and then i get disconnected. I had to do this over and over again untill I finally get through. this happened other days aswell. I chose this brand over ASRock for the support that I thought i'd get from them. so much for that. anyways, when I finally got through, the tech (who didn't seem to know what he was doing) suggested for me to try another HDD. so I plugged in my Seagate 160gb and low and behold, i was able to see the HDD in windows. during post when it shows the marvel controller, it does see the HDD. but for some reason, it doesn't see my WD raptor 74gb. but I still can't see these 2 controllers in the bios. the tech told me to take out the cmos batter and reset the bios by moving the jumper from pins 2-3. I wanted to do it this morning, but first I wanted to backup my current bios. I still have to do that. while playing around with my PC this morning, I unplugged the WD raptor, but broke the sata port on the HDD. so much for that HDD. questions: 1) should I reset the cmos and do you think it will have these marvel ports show up in the bios? 2) why would these ports see my seagate 160gb and not the WD raptor? I know the WD works.

the WD raptor had win7 installed on it and the seagate had data on it.

so I guess I won't do the cmos reset. I already loaded the optimized defaults. what will resetting the cmos do that loading the optimized defaults doesn't?

thanks
