SYSTEM BIOS
The primary function of the system BIOS (Basic Input-Output System) is to provide a series of software interrupts, functions, and sub-functions that control operations on certain devices, such as the hard disk drive, the floppy drive, and the video subsystem.
Hardware Functional Overview
3-3
The SONY Versa 2500 Series uses the Phoenix BIOS. The BIOS Setup program is an easyto-use system utility configuration that sets system parameters and copies them on the Flash ROM chip with the system BIOS. An additional frame buffer/accelerator DRAM increases the available memory bandwidth for CPU accesses.
Video Chipset Controller
The C&T 65548 initiates a family of 208-pin, high performance for the full-featured notebook that requires the highest graphics performance available. The 65548 achieves superior performance through direct connection to system processor buses up to 32-bits in width. When combined with the CHIPS' advanced linear acceleration software driver technology, this device exhibits exceptional performance compared with devices of similar architecture. The 65548 also adds a sophisticated 32-bit graphics hardware engine for the Bit Block Transfer (BITBLT), line drawing, hardware cursor, and other functions intensively used in Graphical User Interface (GUIs) such as Microsoft Windows. Features Summary:
T Highly integrated design (flat panel/CRT VGA controller, RAMDAC, clock synthesizer)
T Multiple Bus Architecture Integrated Interface
Local Bus (32-bit CPU Direct and VL) EISA/ISA (PC/AT) Bus PCI Bus Flexible display memory configurations Two 256K x16 DRAMs (1 MB)
T Integrated programmable linear address feature accelerates GUI performance T Hardware windows acceleration (65548) T 32-bit graphics engine
System-to-screen and screen-to-screen BitBlt 3 operand ROP's Color expansion Optimized for Windows BitBlt format

Hardware Functional Overview
Hardware line drawing 64x64x2 hardware cursor
T High performance resulting from zero wait-state writes (write buffer) and minimum wait-state reads (internal asynchronous FIFO design)
T Supports panel resolutions up to 800x600 T Supports non-interlaced CRT monitors with resolutions up to 1024x768 at 256
colors
T True-color and Hi-color display capability with flat panels and CRT monitors up
to 800x600 resolution
T Advanced power management features minimize power consumption during:
Normal operation Standby (Sleep) modes Panel-Off Power-Saving Mode
T Power Sequencing control outputs regulate application of Bias voltage, +5V to
the panel and +12V to the inverter for backlight operation
T Fully compatible with IBM VGA T EIAJ-standard 208-pin plastic flat pack
External VGA Capability
The SONY Versa 2500 Series notebooks provide a 15-pin female D-type external VGA connector that can be connected to an external video graphics adapter (VGA) type monitor. Another feature of the notebook computer is the ability to auto-sense the display output to both LCD and the external CRT monitor. The notebook provides external resolution of 1024x768 by 256 colors for the SONY Versa 2500 series with 1 MB video memory. The SONY Versa 2500 Series can also provide simultaneous display at 800x600 at 256 colors with the standard VGA DSTN LCD.
KEYBOARD SUBSYSTEM
The Keyboard Subsystem of the notebook is implemented on the I/O Board and Keyboard Assembly using the Motorola M 38813M4 keyboard controller chip. The SONY Versa 2500 Series keyboard is an 87/88-key, IBM enhanced-type keyboard with standard characters and function keys plus 12 programmable function keys. The notebook also provides an external PS/2 port for supporting an external PS/2 keyboard or standard DIN-type AT-keyboard. See Section 1 for more information.
