3.3.2 System Memory

The system memory consists of SDRAM memory on 64-bit bus and the module size options are 128/256/512/1GMB 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.

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 GPIO pins before the VGA chip initialized, and pass this information to VGA BIOS through INT 15 Function 4E00h.

3.3.4 Enhanced IDE

The system BIOS must be ready to support 4 IDE devises on two controllers. The BIOS support Ultra DMA33/66/100 and also supports automatic configuration of drives using both the LBA and CHS large drive remapping method. In addition to supporting standard 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.

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.

3.3.7 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

3.3.8 LED Indicator

The table below lists down the functions of the Status LED indicator:

Indicator Function Description IDE accessing LEDŒ This LED will turn on while accessing the IDE Device. Battery Charging LED Turn on (Blue) – Battery is under charging mode

ScrollLock LEDŒ This LED will turn on when the function of ScrollLock is active. NumLock LEDŒ This LED will turn on when the function of NumLock is active. Power Status LED Yellow – System is powered on.

Yellow Blinking- System is entered suspend mode.

Trun off – Battery Low. Mail LEDŒ This LED will turn on while Mail was arrived.

Œ - These LEDs will be turned off during Suspend mode.
