Question I have H8SGL motherboard and BIOS Rev 1.1c – Build Date 03/23/11; wondering why HDD connected to: Sata0 -> is shown as 3M (ThirdMaster) Sata1 -> is shown as 4M (FourthMaster) Sata2 -> 3S (ThirdSlave) Sata3 -> 4S (FourthSlave) Sata4 -> PM (PrimaryMaster) Sata5 -> PS (PrimarySlave) Why not ? Sata0 -> PM or (SM) -> /dev/sda Sata1 -> SM or (SS) -> /dev/sdb Sata2 -> 3M -> /dev/sdc Sata3 -> 3S -> /dev/sdd Sata4 -> 4M -> /dev/sde Sata5 -> 4S -> /dev/sdd Answer Base on the AMD SP5100 spec, it needs to set the IDE Master and Slave that way.
