Answer 1

You may use the website bios-pw.org for unlocking the BIOS, with the following procedure:

1. Enter 3 times the wrong code in answer to the prompt
2. The prompt will change, asking for a password
3. Press PgUp and then Enter, and a reset key will be displayed
4. Enter that key in bios-pw.org and receive a code
5. Enter that code in the BIOS and hit Enter to get into the BIOS
6. In the BIOS go into the tab that might be named "Security", and click an entry which might be named "Set Supervisor Password".
7. Hit Enter
8. It may ask for the old password, so enter the code from step 4
9. Hit Enter for all prompts for a new password (or enter a password)
10. Exit the BIOS with saving the changes
11. Done. At your discretion you may donate to that website.

This should work, but if it doesn't, see the article How To Remove, Clear, Reveal, Unlock or Reset BIOS Security Password for useful utilities: PC CMOS Cleaner, CmosPwd by CGSecurity, !Bios by eleventh alliance and invalidating the CMOS checksum manually while booting from FreeDOS.

Answer 2

Quite often, the password will be set (either in plaintext or hashed) in a separate EEPROM in the computer, so that the ROM for the BIOS has no effect on it. This also means that you can upgrade or reinstall the BIOS and keep your password and settings on there. This is a huge convenience for businesses, who do not disclose BIOS passwords to employees, yet can still remotely upgrade them. You may have to decrypt or re-flash the security EEPROM or another chip to reset the password, as you might have seen in older style Thinkpads for example.

To answer your question, you should research how to clear the password on the specific model you have - that is, of course, provided you own the machine or have full permission to do so by the owner. It may not (and frankly, shouldn't) be possible any more to do so by simply removing the CMOS battery, but neverless its something to try anyhow. In the worst case scenario, you could learn how to reverse engineer the BIOS chip and inject code to reset it for you, if you are not able to do so manually. This is overkill and it much easier said than done, but then again, if you are willing to decompile the binary from the BIOS you might as well get it commercially done for you or just get another board. All the personal examples I've seen of BIOS disassembly have been done for one's own interest, and simply isn't worth the time to learn (especially since, from your question, it appears you want a quick and easy way of wiping the password).
