Acer Travelmate P255

[Ray2]

Hey All 

Can someone assist me with a bios for this model 
the problems i have are the following

•  cpu states cpu 0000 runs at 0.8mhz 2 core  4 thread)according to some research this model with the gpy came out with an i5-4200u
  
•  the normal bios number of 2.17 (latest)but instead v0.12t4,1/26/2013(on machine)
  
• it has a ati hd8750 2gb gpu( which i think is odd running such a crappy cpu)
  
• And last but not least none of the serial numbers seems to work even if i download the software from Acer's website to check my serial number. 
  

i heard talks that it might be an engineers machine and the current bios is open however i have no idea how to clock it
Thanks in advance for your help
