Hardware Functional Overview
4.8.1 System
Memory
The notebook offers two 64-bit SODIMM (Small Outline Dual Inline Memory Module)
sockets for main memory configuration. The memory sockets accept any standard 144-pin
SODIMM modules at 16MB, 32MB, 64MB, 128MB and 256MB sizes. Memory modules are
3.3V SDRAM type.
4.8.2 Video
Memory
The video memory of the notebook is embedded inside the VGA controller chip (S3 Savage
4) with 8,16 and 32MB SMA video memory that can support display resolutions of up to
1024 x 768 at 32-bit 16M color (TFT LCD).
4.9 System
BIOS
The notebook utilizes the Phoenix BIOS 4.0 Release 6.0 (Basic I/O System) that contains
both the main system BIOS and the VGA BIOS with Shadow BIOS capability. It utilizes
Flash EPROM BIOS that allows instant erasing and programming without replacing the
EPROM chip.
The BIOS is stored in a 32-pin PLCC package FLASH ROM SST 28SF040A-90/120 or
Winbond W29C040P-90 with 4Mbit size and is mounted into the motherboard. While posting
the system, the Shadow RAM will be enabled and the ROM will be disabled.
4.10 Video Subsystem
The video subsystem, integrated inside the North Bridge chip and the LCD panel, controls the
display output to both the LCD Panel screen and to the external VGA port.
