Remove the CMOS battery for at least 10 minutes and replace it.

Look in your manual how to clear the CMOS, usually done by using Clear CMOS
Jumpers.

thats not true for every mother board the battery does support the bios
settings on quite a few I have had

Every board I have, you had o do this by the CMOS jumpers. Thanks for the

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.]]

There should be a jumper switch on the motherboard for bypassing theNicholas said:i have forgotten my BIOS password - how can i access it?
