There's support for it there. Anyway, did your board suddenly die? Do you have floppy access?

Thanks guys for the help. Anyway, my mobo doesnt have any video signals
nor beeps from speaker. I am now trying to check the caps first using esr meter. Then I will proceed to what you have suggested to me through this post. Thank you so much. Will post soon the results.

LuckyStar clone board. Not the best of brands. Have you checked ALL the caps for any bulging? The little ones go too after a while...

yes, I already do the full visual check with magnifying lens on both sides of the mobo looking for something unsual. after that I use esr meter to check the health of the caps. found one and successfully replaced it. after that I use uniflash to update the bios file and still successful. But still no go.

Check if all voltages are present and correct (3.3V for chipset - on DIMM slot pin 6 IIRC, VCore and VTT for CPU and 2.5V for clock generator).
