Page 32: Processors
Chapter 2 System Overview 2.4.1 PROCESSORS The Compaq iPAQ family includes models based on Celeron and Pentium III processors. These processors are backward-compatible with software written for the Pentium II, Pentium MMX, Pentium Pro, Pentium, and x86 microprocessors. Both processor architectures include a floating- point unit and first and secondary caches providing enhanced performance for multimedia applications.
Page 33: Figure 2-7. Processora
2.4.1.3 Processor Upgrading All models of the Compaq iPAQ use the PGA370 zero-insertion force (ZIF) socket for processor mounting as shown in Figure 2-7. Raising the Lock/Unlock handle of the socket in the vertical position allows the processor to be removed or inserted into the socket. Lowering the Lock/Unlock handle in the down (horizontal) position locks the processor in place.
Page 34: Chipset
Chapter 2 System Overview 2.4.2 CHIPSET The Compaq iPAQ employs the Intel 810e chipset, which is designed to compliment the processor and provide the central point for the system’s data transactions. The chipset is composed of a graphics memory controller hub (GMCH), an I/O controller hub (ICH), and a firmware hub (FWH).
