Resetting or recovering a forgotten BIOS/CMOS password can be a tough nut to crack as usually it requires opening the case and sorting BIOS battery. If you are able to boot into Windows, free utility CMOS De-Animator lets you do this without going through the manual procedure using just a single button click from Windows.

CMOS De-Animator basically clears the BIOS RAM, by smartly invalidating the CMOS verification checksum which results in resetting of all BIOS settings to default including the stored BIOS passwords on reboot.

Opera features an excellent password manager - Opera Wand, but provides no means to see saved password in Wand, I found myself into similar trouble and had to use a simple trick to recover saved password in Opera, we will be using the old school javascript trick to reveal hidden passwords in Opera.
