X9SCL-F boot from sata 4 or 5

[ybcnyc]

hi

i bought 1U Supermicro with X9SCL-F Intel Xeon E3-1220 8GB to keep as VM backup server for 4 host proxmox cluster.
the server has 6 sata ports onboard from which 4 (0-1) are connected to the 4 bay hd backplane. when i connect a ssd to one of the two remaining ports the HD gets recognized by the BIOS but i can't select is as a boot device. It only allows me to select one of the drives hooked up to the backplane, but i'd like to use the 4 bay for JBOD zfs config. anyone know if there's some workaround for it or is usb boot my only option ?

thanks

It would definitely surprise me if it weren't possible. You must be missing something...

just an update. i flashed the latest bios for this motherboard and it appears to be working. SSD as boot (inside case) and 2 x 2TB (on a 4 bay backplane) in mirror for data on freenas 9.10. yes it was strange but i'm glad it's working the way i wanted it to. thank you for your advice.
