Setting sector size on ICH10DO

I recently purchased 4 2TB Seagate drives for use in a 6TB RAID-5 array. I am running Windows XP 32-bit, which can only recognise drives up to 2TB in size using the default sector size of 512 bytes, so I intended to create the array and specify its logical sector size as 4KB which would allow expansion to 16TB in theory.

Unfortunately I can't find an option to specify this in the Intel RAID BIOS or the RST management console. After I create the array I can expand the "Advanced" option and see that the settings "Physical sector size" and "Logical sector size" are both set to 512 bytes, but I need a way to set "Logical sector size" to 4KB during array creation. Is there a way to do this?

XP 32 bit dose not support GPT it only supports MBR.

The "Physical sector size" and "Logical sector size" have nothing to do with limiting the array size to 2TB.

Note: Intel only supports an a array size past 2TB if it is a data only array which is to say you can't have a OS on it.
