User manual SONY VAIO VGN-NW242F/S

[. . . ] Cache Memory Subsystem ­ implemented on-die on the Intel CPU. Video Subsystem ­ integrated on the motherboard using S3 Savage IX VGA chip and on the LCD Panel for supporting the LCD and CRT. PCMCIA Subsystem ­ implemented on the motherboard using the O2Micro OZ6933 PCI-CARDBUS BRIDGE controller chip. Audio Subsystem ­ implement included on the VT82C686B. [. . . ] By incorporating the cache on-die (meaning it is combined with the CPU into one component), Intel eliminates the need for separate components. The 256KB 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, imple mented on the motherboard, includes System and Video memory. The VIA Twister System Controller chip provides primary control for the system memory. FIC VAIO VGN-NW242F/S Service Manual 4-9 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. 4. 10. 1 Video Chip Controller S3 Savage 4 also includes 8, 16 and 32MB of shared architecture memory (SMA) with all of the above in a single BGA package.

SmartCardBus lowers the cost of ownership of e-commerce and corporate security Smart Card applications. 4. 12 Audio Subsystem The audio subsystem is integrated inside the South Bridge chip on the motherboard. Refer to the System Core Logic section of this chapter. An internal two-way mini speaker and microphone provide the notebook with mobile sound generation and recording capabilities. In addition, a set of 3. 5mm bayonet socket (1/8" minijack) connectors allow for external microphone, line inputs, and headphone outputs. 4. 13 Keyboard and Pointing Device The Keyboard Subsystem of the notebook is implemented on the Motherboard and Keyboard Assembly using the Mitsubishi 38867M8 keyboard controller chip and the Phoenix MultiKey/M3886L keyboard controller firmware. This chip controls the internal built-in keyboard, the built-in touchpad pointing device, as well as the external PS/2 keyboard and mouse port. The keyboard controller allows simultaneous use of both the internal and external keyboard and PS/2 mouse. The VAIO VGN-NW242F/S membrane keyboard is an 86-key IBM 101-key enhanced compatible keyboard with standard characters and 12 function keys including an embedded numeric keypad. The pointing device subsystem consists of the built-in Synaptics touch pad pointing device module on the system top cover assembly and a pre-programmed Mitsubishi 38867M8 microcontroller that interfaces the mouse device to the Motherboard. The touch pad module is connected to battery board through a 6-pin FPC cable. An external PS/2 port also supports the use of an external PS/2 compatible mouse where the system automatically detects on system power up and runs both internal and external mouse simultaneously. The Synatics touch pad, a pointing device for personal computers, detects the position of a finger over a touch-sensitive area. [. . . ] The cursor continues to coast in the indicated direction when the finger is held against the edge. 4. 14 Disk Drives Subsystem The disk drives subsystem, implemented on the Motherboard and on the associated internal hard disk drive assembly and device bay, provides disk storage for all system software and user files. The notebook is equipped with high capacity hard disk drive using Enhanced IDE controller with LBA (Logical Block Addressing) and Ultra DMA mode support. The VT82C686B controller chip provides the Primary IDE controller for the internal hard disk, and the Secondary Master for the CD-ROM. The floppy disk drive supports standard 3. 5-inch 720KB and 1. 44MB mini-diskettes while adding support for 1. 2MB (3 Mode) mini-diskettes for Japanese market. [. . . ]
