difficulty in breaking cmos password

well, that's kinda the whole POINT behind a bios password now isn't it?

the operating system doesn't mean a hill of beans if it wont even boot up into windows , my suggestion would be to wipe the bios, as in clear it. check the documentation to find out how to do this, that might do it.

only way to do it would be to remove the battery and blow the bios. you used to be able to use jumper 17 (short) and that would wipe all passwords not sure if you can still do this.
dont forget your passwords

For IBM laptops, you need to take the laptop along with proof of ownership to an IBM repair center.

They have the tools to reset the password.

For nearly ALL notebooks, there is no way for the user to recover a forgotten password. This is part of security features to make stolen laptops have less value.

On some laptops, you need to actually replace the BIOS IC and re-program it to recover from a forgotten password.

Sorry the bios password is not stored in the bios chip. The newer motherboards have a security chip that it stores that information in.

You will have to replace that chip, or get IBM to backdoor the password.
