SOURCE: Bios default password
The BIOS default password is just blank, and it is not asked.
When you set a bios password, you are asked to enter a value, therefore if bios is asking the password, the password had been changed.
To reset the bios password if you do not know the password you need to access to motherboard and temporarily remove battery for few seconds.
Removing battery will reset bios and delete the password.
Unplug power cord before accessing the motherboard, and try not touching the motherboard with your finger.
Put battery back in place before restarting computer.
