then why was my mouse movement all wonky with 2.1 and as soon i flashed 1.7 it was resolved? why isnt each newer bios a bigger file than the previous ones? why is 1.7 a bigger file than 2.1? so youre telling me all the fixes are in 2.1 even though its a smaller file? the reason u update to a bios is to fix a certain issue..not resolve all issues previously
