The BIOS model needs to help the parameters of the microprocessor. If a 500MHz Pentium III processor have been put in in a approach whose BIOS in simple terms helps processor accelerates to 400MHz, the BIOS will basically file a processor velocity of 400MHz in the course of the submit component of the startup. 2. d. The Athlon is a Pentium III clone processor that's on hand in a Slot 1 automobile- tridge clone, referred to as the Slot A specification. three. d. the unique Pentium III processor was once designed round the Pentium II center, yet elevated the L2 cache dimension to 512KB. four. b. ahead of Pentium II, all Pentium processors used 50, 60, and 66MHz exter- nal clock frequencies to generate their inner working frequencies. The Pentium II processor moved to a 100MHz exterior clock and entrance facet bus. five. b. The Pentium professional 512KB L2 cache enhances the 16KB L1 cache within the Pentium seasoned center. The L2 onboard cache shops the main usually used information no longer present in the processor’s inner L1 cache, as as regards to the processor center because it could be with no being built-in at once into the IC. 6. c.
