Internal Design
The motherboard PCA is the central component of the Omnibook’s design. It plays a role in virtually
all system functions. The CPU module and most other subsystems connect to the motherboard.
The following figure shows the connections among the Omnibook’s replaceable electronic modules.
Table 1-9 on page 1-15 lists the roles that these modules play in the Omnibook’s functional
subsystems.
