I understand that you have problems utilizing the Intel® RAID Controller RS25DB080 card the Intel(R) Desktop Board DQ57TM.
Intel(R) does not fully validate the usage of SAS controller cards on desktop motherboards. There is an option in BIOS called expansion card text that will sometimes help you with the proper recognition of the card and helps the boot to the operating system. The option will usually be found on the security or boot tab.
sorry , i tried but still cannot work
i search the forum and many peoples have problem with intel DQ57TM and Raid controller.
too sad that they are the same intel products but not compatible.
