I have disconnect the PATA drives, disabled PCI IDE embedded controllers, and activate the function "Scan User Flash Area" from BOOT Menu.
Two seconds away from POST ending, appears the message "reboot and select proper boot device or insert media in selected drive" in white character on black screen. The mainboard BOOT correctly from LANcard and USB external device !! Now, the SATA disk work as D: drive on mainboard... perfectly.
Is the D845GRG BBS compliant ? Do the BIOS scan the IDE slot for seek a FlashROM boot?
How can i control if the MB seek (or not) the PCI slots for boot and how can i know if the PCI card allowes boot by SATA HD plugged from itself?
