I don't know if there is a bypass readily available for this model or not, but pre-programmed chips are $35 and require moderate soldering skills to remove the old one and install the fresh chip. A hardware bypass will always work if you can't find a software method.

None of which work sofar

The current plan is to go the hardware route

Just take the BIOS battery off and put it back.

I haven't had success with this. The only thing that happened with the above method is that after a few tries, the laptop I was trying to change the OS on would no longer POST.

It can't be accomplished.

new machines that are being made now this cannot be done as the security is saved on the bios chip as the first response claims replacing the bios chip is the only option if you cannot do it bring it to a repair shop
