but not can update why fail the bios,machine running slow…
help me…

You’ve posted this a number of times in the past so here is what you don’t understand:

1) There is no ME8 Mac SKU, the latest ME8 1.5MB is fine for such systems too
2) Your MAC being slow has nothing to do with ME, you should look elsewhere
3) Not being able to update the BIOS or similar issues again have nothing to do with ME
