Hp pavilion ze4600 bios pw

i have a hp pavilion ze4600 and the bios is asking me for a password. however i read some things on this site concerning hash codes and stuff like that. idon't know how to get a hash code or how you go about to generating them or even how to insert it and bypass the bios password. i would really appreciate it in advance and hope that i could get a positive result on this issue.
please help if you can!:)
 
Hi I am having the same trouble. To access your hash code when the blue box comes up and asks for the password press the F12 key and this will generate your systems hash code.
