Jmicron 362 works only in ATA-Mode

Need assistance :
Mainboard ASus AT5NM10T-I with 4 SATA 300 Seagate 2TB.
Two drives work fine -AHCI and 300MB/sec - two drives connected to the Jmicron 362 chip work as IDE -ATA drives with 30 Mb/sec. :(

What can I do, to switch the 362 to SATA-Mode?

Thanks in advance
Rolf
 
JMicron 362 is a PCI chip. It by definition can't give more then about 120MB/s total because of that. What's about mode, SATA ports of that chip support AHCI, but that switch is usually done by BIOS. I have no idea how to do it otherwise.
 
Unfortunately my bios gives only the choice to disable or set to IDE.
Could maybe the ata-driver resolve the problem??
 
Did you locate the documentation or find out any way to enable SATA on the JMicron 362?

I am using FreeNAS and having a similar issue whereby the OS only reports the drives as capable of 33MB/s, I also have no option in the bios other than IDE or Disabled
