S3200SH with 3TB drives

Hello,

I have S3200SH board and want to create RAID5 array of four 3TB drives (I have also another RAID1 array, but that one works fine). I am using Intel Matrix Storage Manager as a raid controller. I have updated board bios to the current version, but in the raid configuration utility, I see the 3TB drives as 746GB drives.

I have done some research and found that drives >2TB are supported from Intel Matrix Storage Manager oprom v 10.something, but the newest board bios update installed oprom v 7.5.0. Is there any way how to update just the oprom, or any other way how to make the raid configuration above work?

Thanks

Petr Ent
