what you are thinking about when you say "The only function of the BIOS 
is to load the OS".  A BIOS used in a very popular laptop has seen 17

2. Minor changes for ASF progress PETS, including adding Dock, video and 
System Setup PETS.
3. Allow ASF to force PXE boot even if the on-board NIC isn't set to 
"Enabled w/PXE" in System Setup.
4. Added support for new versions of Intel CPUs.

power is inserted.

bug with KMS activation.
