[OpenIndiana-discuss] sata hot plug problem (ahci?) + openindiana crash

[Pablo Oddera]

Hi there,

I have been on the same spot. Some Motherboards that have more than 4 SATA
ports, with less than 5 disks there is no problem but if you want to use
the fifth port you need to choose AHCI or RAID in order to make it
work.Also, check for errors on the dmesg. I had tons of problems with IDE
mode and Openindiana as i installed the OS on AHCI mode. I have to change
the config every time that my BIOS gets cleared.

Best regards
