Thanks for the info.

Unfortunately it doesn't work on my machine.

I think I'll have to strip it for parts at this point.

Hey @fireberd -- when I click on that link for the "Dell's policy on a corrupted BIOS update", it takes me to a page that says "Access Denied. You do not have sufficient privileges for this resource or its parent to perform this action."

Can you paste a copy of it instead into the thread?

Thanks
