Introduction Notebook Functional Description
This section describes the notebook theory of operation.
Functionally, the notebook computer consists of the following major subsystems: Processor and Memory Subsystem I/O Subsystem Video Subsystem Hard Disk Subsystem Floppy Disk Subsystem PCMCIA Subsystem Serial Infrared Subsystem Power Subsystem
A functional block diagram of the Extensa Notebook is shown in Figure 4-1.
Processor/Memory Subsystems
The Processor function, housed on the Main Board, is implemented with a 75mhz IntelDX4 Processor. The processor operates in conjunction with RAM and ROM Memory on the Memory Board and other control logic on the Main Board to process software instructions (BIOS, Windows 95, and Applications). Primary control for the Processor/Memory subsystem is implemented with the M1429L PC/AT Chipset. Address buffering and real time clock function is implemented with an M1441L. The memory subsystem, implemented on the Memory Board and optional Dual Inline Memory Modules, provides 4MB (expandable to 32 MB) of fast DRAM memory, 128 bytes of CMOS RAM (battery backed up) and 256 KB of Flash ROM for system and video BIOS storage. Tables 4-1 through 4-3 contain the Notebook I/O address map, DMA channel assignments and IRQ interrupt level assignments respectively.

Caution: Formatting the disk drive erases any data that may be stored on the disk. Therefore do not attempt a format of the hard disk unless the computer self-test and diagnostics confirm that the disk has not been formatted.
A Hard Drive activity LED is located along the front edge of the notebook. This LED lights during hard driver read/write accesses.
Caution: The notebook should not be moved when the HDD LED is lit to prevent accidental damage to the hard drive.
Floppy Diskette Drive Subsystem
The Floppy Diskette Drive Subsystem consists of a Floppy Controller and the Floppy Diskette Drive. The Floppy Diskette Drive can read/write standard 3.5-inch minidiskettes.

PCMCIA Subsystem

The notebook is equipped with an on-board PCMCIA host adapter (CL-PD6722 PCMCIA Controller) and sockets to support one Type I or Type II option or a Type III option if the Floppy Drive is removed from the unit. The PCMCIA Controller has the following features:
