4.7 Cache Memory
The primary (L1) and secondary (L2) level cache are integrated on the CPU. By
incorporating the cache on-die (meaning it is combined with the CPU into one component),
Intel eliminates the need for separate components. The 512KB on-die L2 cache provides
three (3X) times faster processor access, resulting in significant improvements in
performance. Likewise, an integrated cache means a reduction of connections resulting in
increased reliability.
4.8 System Memory
The memory subsystem, implemented on the motherboard, includes System and Video
memory. The Intel 852GM System Controller chip provides primary control for the system
memory.
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 128MB, 256MB,512MB and 1GMB sizes. Memory modules are
DDR 200/266 SDRAM type.
4.8.2 Video Memory
The video memory of the notebook is using share system memory with 8~32MB UMA
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 49LF040A 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, embedded 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.
