3.3.2 System Memory

The system memory consists of SDRAM memory on 64-bit bus and the module size options are 64/128/256MB upward. The BIOS will automatically detect the amount of memory in the system and configure CMOS accordingly during the POST (Power-On Self Test) process. This must be done in a way that requires no user interaction.

3.3.3 Video

The Video subsystem us ed share memory of Video memory. The system will support the true ZV port, the Microsoft Direct 3D assist, simultaneous display, monitor sense for auto display on boot and VESA Super VGA function call.

Supported Video Mode

The following is the display mode s supported by the S3 Savega4 in LCD only, CRT only, and simultaneous mode. The VGA BIOS will allow mode sets of resolutions greater than the panel size but only show as much mode display as will fit on the panel.

Panel Type Initialization

The VGA BIOS will issue INT 15h function call during POST. This function call allows the system BIOS to specify the panel type to the VGA BIOS. The system BIOS should get the panel type from GPI pins before the VGA chip initialized, and pass this information to VGA BIOS through INT 15 Function 5F01h.

Supported standard VGA modes:

The VGA BIOS supports the IBM VGA Standard 7-bit VGA modes numbers.

3.3.4 Enhanced IDE

The system BIOS must be ready to support 4 IDE devices on two controllers. The BIOS support Ultra DMA 33 and also supports automatic configuration of drives using both the LBA and CHS large drive remapping method. In addition to supporting sta ndard drives through an auto-configuration process that does NOT require user involvement or confirmation. The system should automatically do this at POST time in a way that is transparent to the user. If a drive is connected to the bus, the drive should be automatically recognized, configured and available for use under MS-DOS 6.2x.

Ultra DMA

Ultra DMA 33 is a physical protocol used to transfer data between an Ultra DMA/33 capable IDE controller and one or more Ultra DMA/33 capable IDE devices. It utilize s the standard Bus Master IDE functionality and interface to initiate and control the transfer. Ultra DMA/33 utilizes a “source-synchronous” signaling protocol to transfer data at rates up to 33 Mbytes/sec.

3.3.5 Audio

The audio subsystem will support the requirements identified by the AC’97 specification. Both software and hardware will control the volume level for the internal audio subsystem. In addition to the volume control, the user will be able to mute the sound to completely cut off the volume using both software and hardware.

3.3.6 Super I/O

This controller contains 16550A or FIFO Enabled UART, ECP/EPP/Uni-directional Parallel Port meeting the 1284 specification, and an Infrared port.

3.3.7 PCMCIA

The PCMCIA controller chip of the notebook provides the following features:

• Individually accessed, dual-buffer implementation

• Support for 2 separate CardBus slots (one type III or two type II stacked)

• Support for 3.3v, 5v and 12v (flash programming) cards
