Forgott bios password on HP d330m

Hello.

I have an HP d330m Micro tower computer where i have installed a new AGP grafix card, when i start the computer i get an error so i checked this up and i have to change some bios settings to remove the error message.
But i dont have the password anymore
I have tried removing the battery but no luck.
I have tried to flash bios but in the middle of the process it ask for the password, and then it quits.
I have also tried with some software, dont rememver the name of it but it did not work either
I have also been in contact with HP support, they could not help

Can someone help me here?

Most computers manufacturers have a master password hardcoded into the BIOS for this very problem. Years ago, in the early 90's, I had a problem with my password. Obviously I spelled it wrong, typo'd it, something, but the password wouldn't let me into the computer. I called them and they gave me a master password so I could access my computer (which, oddly enough, was MASTER ) Or, you could simply reset the CMOS, as stated above.
