Bypassing the BIOS password of newer Dell models with a service tag ending in -1F66 is still only a trivial exercise in patience:
DELL service tag: DELLSUX-1F66 password: qHXaL0ntli6Gu4c0
The algorithm used to derive the password from the service tag is just a minor modification of the crap seen before. Is public-key cryptography really that hard to understand?
