Acer 240 BIOS Password

Hi everyone. Hope you can Help. I have a Bios password on an acer I bought. Never realised until I went to reload windows but I cannot now change to boot to CD First.

Is there a software fix or do I need to solder a new in. If someone could tell me where the chip is I have an old motherboard which I spilt some liquid on a while ago.

Thanks

Just clear CMOS. There is usually a jumper on the Motherboard to do this but when all else fails remove the Motherboards Battery for about an hour place it back in and presto.
