Hello Laios,That message is because you have not connected any devices to JMicron SATA connecter.(see page 2-7 and 2-33 of manual).You can disabled this message by Disabling J-Micron esata/PATA controller in BIOS. (See page 3-28 of manual).BR
Not only for e-SATA but also IDE and JMicron SATA as well. (See page 2-33 of manual)
Because the ICH10 chipset will not support IDE devices any more.BR.
Hello joschi4,YES if you have any devices that you want connect other than 6 SATA that you have connected to ICH10 chipset.NO if you do not have any devices to connect other than 6 SATA that you have connected to ICH10 chipset.BR.
