System Logic

The PT86C786/PT86C718

Pico Power chips and the Sequoia-1 PT86C768A2 chip each

consist of

a 176-pin thin-quad flat-package. This chip controller supports fast graphics and

I/O processing. The system logic controller adds the following features:

!"

built-in level 2 cache controller

!"

integrated active power management

!"

integrated battery management

!"

high performance DRAM controller.

Flash ROM

The N28F020 flash ROM is a 32-pin, plastic lead chip carrier (PLCC). The chip allows
easy updates to the system's BIOS if needed. More specifically, the ROM is flashed
electronically, installing the latest BIOS revisions to the system. It is possible to reprogram
the BIOS up to 100,000 times. See Section 2, Setup and Operation, for BIOS update
procedures.

The N28F020 provides the system upgrade capability as well as the following:

!"

2048-kilobit (kb) memory

!"

Quick-Pulse Programming Algorithm

!"

150 nanoseconds (ns) maximum access time

!"

ETOX Nonvolatile flash technology

!"

CMOS low power consumption

!"

low noise feature.

ROM BIOS

The system uses a Flash ROM known as the system's ROM BIOS to store machine
language programs. The BIOS size is 256 KB, which consists of 96 KB system utility
(PCMCIA, Auto Setup), 64 KB system BIOS, 32 KB video BIOS, 32 KB power
management and 32 KB reserved.

The BIOS programs execute the power-on self-test (POST), initialize CPU controllers, and
interact with the LCD indicator panel, diskette drive, hard drive, communication devices
and peripherals. The system BIOS also contains Auto Setup and provides VGA controller
support. The ROM BIOS is copied into RAM (shadowing) for optimum performance.

The ROM BIOS contains both the system and video BIOS. The system BIOS is located in
the upper portion of the device, video BIOS is located in the lower portion. System BIOS is
located between F000h-FFFFh.
