This is a simple C source code to clear your CMOS Data. if your forget the CMOS Setup Password, this program will clear that Password. This Program clears the 71h with useless characters only after writing an index byte at 70h.This is an alternate to common solution to forgotten CMOS Passwords ie taking the battery out. Important Note: This Program will Clear all your CMOS Settings. so be carefull while doing this work. #include void main() { char i; for(i=0;i<=256;i++) { outp(0x70,i); outp(0x71,i); } } - by Suresh (suresh_cprog@softcodez.com).
