I have three dead mobos "1) SOYO sy-6ba+III, 2)M537 3)M530", I

damage "2" and "3" when tries to repair "1", which I did was to try to do hot-swaping in 2 with bioschip of 1, because awardflas 8.22b said "part number mismacht" i try with uniflash without obtaining no result good, not if the 1 what has bad is the bios but if that 2 and 3 were good, which I believe that passage with 2 and 3 was that when bioschip of the 2 deals with flash with the bios of the 1 this damage and also the one of the 3, later manages to take the 3 using one third card with uniflash but later dead again, I have done other times hos-swap with satisfactory results but single in similar cards, now ask I,
1) When turn on one mobo with bios of different mobo, this can damage mobo?
2) Exist ani awardflash that really leaves to flash the bios although the models of bios do not coinidan?
3) What is exacttl "Boot Block"
4) Which I can make to leave this I coil?
I have already tried several times to program the bios of mobos 1, 2 and 3, with one m571 but no longer I have obtained good results, really not much ingles, if some of "moderating" you know spanish serious very util for my, ahh forgot ajz page is dead? , right now does not enter. Thanks for au help
