is it safe to flash a modded bios image with slic inserted to your board? will it result in some sort of damage? or there is noting to worry about? since the only differences compared to the stock bios is that the modder insert slic? and it will not stay there permanently after a reflash? will it somehow leave some trace or anything?
Flashing any bios, even stock, is risky and can result in a bricked motherboard. Some bios have crisis recovery, some do not. Some SLIC mods can stay after a stock re flash, some do not. There are too many different combinations to generally say yes or no.
