At this point I would probably swap the bios chips over just to confirm the good main chip can boot in the bad backup's bios socket. I would also attempt to flash the bad chip again in its new socket. This may be risky & you may bork both of them leaving you with an un bootable board. I have a bios chip flasher so would not bother me personally. Perhaps a safer! thing to do at this point would be to attempt a hot flash.

I have not had the need to hotflash for many years however it should still be doable. Basic upshot is remove both bios chips & lightly seat/replace the good main bios chip in its socket with a thin piece of string like sewing string under it then lightly replace it. The idea is to boot to dos/bios then pull on the string to pop the chip out whilst the board is running. You can then insert the bad backup chip & flash it from dos/bios. You could even boot to windows then pop the chip & flash in windows.

Only things I can see going wrong would be you may have to boot with both chips installed as the board may check for the backup bios on post & fail to do so if its not in place.
i need a bit more details on this hot flashing stuff ...
u mean i have to physically remove n replace the bios chips ...
by the way my motherboard is still under warranty should i not try to send it for RMA claim ... n then try something if it is still faulty ...
