Question about Computers & Internet
Here's a document I've filed away for this sort of problem. Sorry I can't recall where it came from,......
BIOS PASSWORDS BY MFG
VOBIS & IBM merlin
Packard Bell bell9
Most Toshiba laptops and some desktop systems will bypass the BIOS password if the left shift key is held down during boot
Go online & look for these jewels ;
!BIOS (get the how-to article)
Removing the CMOS Battery
The CMOS settings on most systems are buffered by a small battery that is attached to the motherboard. (It looks like a small watch battery). If you unplug the PC and remove the battery for 10-15 minutes, the CMOS may reset itself and the password should be blank. (Along with any other machine specific settings, so be sure you are familiar with manually reconfiguring the BIOS settings before you do this.) Some manufacturers backup the power to the CMOS chipset by using a capacitor, so if your first attempt fails, leave the battery out (with the system unplugged) for at least 24 hours. Some batteries are actually soldered onto the motherboard making this task more difficult. Unsoldering the battery incorrectly may damage your motherboard and other components, so please don't attempt this if you are inexperienced. Another option may be to remove the CMOS chip from the motherboard for a period of time.
Note: Removing the battery to reset the CMOS will not work for all PC's, and almost all of the newer laptops store their BIOS passwords in a manner which does not require continuous power, so removing the CMOS battery may not work at all. IBM Thinkpad laptops lock the hard drive as well as the BIOS when the supervisor password is set. If you reset the BIOS password, but cannot reset the hard drive password, you may not be able to access the drive and it will remain locked, even if you place it in a new laptop. IBM Thinkpads have special jumper switches on the motherboard, and these should be used to reset the system.
Overloading the KeyBoard Buffer
On some older computer systems, you can force the CMOS to enter its setup screen on boot by overloading the keyboard buffer. This can be done by booting with the keyboard or mouse unattached to the systems, or on some systems by hitting the ESC key

Yes by default the bios is unprotected/no password. All you have to do if you want to setup bios password just go to bios then create supervisor password then it will have password everytime you need to access the bios. For info. bios password is not related to re-installation / installing your OS.
