BIOS  (Basic  Input/Output  System) - the program logic used to boot up a computer and 
establish the relationship between the various components.  
Driver - software, which defines the characteristics of a device for use by another device or 
other software. 
Processor - the "central processing unit" (CPU); the principal integrated circuit used for 
doing the "computing" in "personal computer"  
Front Side Bus Frequency 
The working frequency of the motherboard, which is generated by the clock generator for 
CPU, DRAM and PCI BUS. 

CPU Internal Frequency 
The frequency of CPU, which is also the actual working frequency of CPU. 
 
 

Bus Frequency Ratio 
The ratio of the working frequency, multiply Front Side Bus Frequency with Bus 
Frequency Ratio will form the CPU Internal Frequency. 
CPU L2 Cache 
The flash memory inside the CPU, normally Pentium III CPU has 256K or above, 
while Celeron CPU will have 128K. 

 

The way to recognize the specification of CPU from the packing Pentium III 370 
pins FC-PGA 
On the surface of the CPU as shown on the 
right picture, under the word of “PENTIUM 
III” the code is:  
RB 80526 P2 866 256 
RB :  

FC–PGA packing 

P2–133MHz front side bus frequency 

 

   

PY–100MHz front side bus frequency 

CPU internal frequency, where here is 

  

  

 866MHz 

the size of L2 cache, where here is 256K

 

 
Celeron FC–PGA 
On the surface of the CPU as shown on the 
right picture, under the word of “Celeron” 
the code is:
