hi
most of new motherboard's bios are on flash memories, and the user can program it without using any programmers just with a simple software through dos or windows. as C-MAN said , may be you used wrong adapter to program it, so the most easy way is to:
- find a pc with motherboard the same as yours , and when it is running in windows or dos, replace its rom and put your damaged rom (be sure that it has no risk) but do it carefully, then program the flash with the file you have(you can find many tools of programming flash on net), then replace your own flash memory with the original and
if you did it well it would be run on your motherboard.
