Resting by password cracking software –

We can also reset the bios password by the cracking software’s like “Hirens.BootCD.15.2.zip”. We also use Hirens Boot CD because it’s bootable software which contains numbers of diagnostic tools and a live operating system.

Step 1 – Boot the “Hirens.BootCD”

Open the boot menu by pressing F9, F10, F11, F12 whatever your motherboard support’s and Select the DVD-RW to Boot Up the CD.

All the cmos and bios setting is saved in the bios chip which was attached on the motherboard. The main work of cmos battery is giving a continuous power supply to the bios chip to save all the settings. If you unplug or remove the battery for above 5 sec, the bios setting will be reset.
