BCM made in flash ok but not ok Bios flash.
You need to give more details then that man... Does it post at all, does it power on and then off with no video, is there any audible beeps?
Have you pulled the cmos battery? does that change what happens?
Did you follow ALL of the instructions when flashing the BMC/Bios ? Did you skip any steps ? Did you flash the BMC but not the BIOS ?
We need more details of what you have/havn't done and what the exact symptoms are before anybody can help...
