No Access to BIOS but need Laptop CD-ROM Bootable

Posted on 2008-10-29
Last Modified: 2013-11-17

It's an old HP Laptop Omnibook 4150
Left it unused for years, and cannot recall the BIOS Password.
It has Windows 2000 on it, all working fine
Without BIOS Access, I cannot update the Boot Order...
Would there be any other means such as to install or add anything inbetween the BIOS and Windows loading that would display anoption to boot from CD-ROM?
There are bootloaders but so far they seem to be specifically for multi OS install.
I would need an intermediary that would be loaded before Windows 2000 start...
Any idea?

Many thanks.

You can try to use a free tool called "killcmos".

it erases the bios. Your AV may alert as a virus so you have to disable it whilst you create a boot disk.

remove the cmos battery, or reset the bios; check the manual for how to do it

downloading bios won't help, since you can't do anything need the password, otherwise you have a paperweight.

You have two options:

If  you can prove that you are the owner of the laptop you can contact Hp directly and they will guide you on how to reset the password. Please see PAQ:

If not, you can buy a security chip that will unlock it for you.

I hope this helps.

According to the manual on page 69
Press ESC twice during bootup to see if the CD-ROM drive is the first boot device.
Don't know if this will allow you to change the boot sequence, but you can give it a shot
