Yes , that is exactly what I got from http://www.siliconimage.com/. Every report I read about ASUS A8N-SLI Deluxe/Premium gave the same technical specs: the second RAID5-capable SATA chip (SilI3114) is attached to the 32Bit bus (*NOT* PCIe). Also, there is *NO* 64Bit bus on any of the mentioned mainboards! And, by the way, the nForce4-SLI MCP is capable of NCQ, but the capability is *NOT* AHCI conform, so it seemes to me that we need a special treatment using this add on - but we all know how restricted nVidia is offering internal details about their chipset to open source projects like FreeBSD. This is what I found out searching the net, some articles and watching this list. Oliver
