Hello all Recently i got X7DCL-3 motherboard with LSI 1068e contoller. All i wanted to do was to change it from IT mode to IR mode. I used this firmware: http://www.mediafire.com/download/4y0a82nhaqrmz47/LSI+SAS1068E+Controllers%28P20%29Linux.zip but it seems that it was not a good choice. During the flash it stopped on resetting adapter and didnt go any further. Ive backed up old firmware but it wont allow me to flash it now because sasflash says theres no adapter installed. I can see that adapter is still there using lspci command. Is there any way to restore original firmware or its already dead?
