4.4 System
4.4.1 System Memory
The system main memory consists of SDRAM on 64-bit bus. The memory size options range from
32/64/128 MB 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 GPI pins
before the VGA chip initialized, and passes this information to VGA BIOS through INT 15 Function

4.4.3 Enhanced IDE
The system BIOS supports 4 IDE devices on two controllers up to 8 GB capacity. 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 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.
4.4.4 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 volume control, the
user will be able to mute the sound to completely cut off the volume using both software and hardware.
4.4.5 Super I/O
This controller contains 16550A or FIFO Enabled UART, ECP/Standard/Bi-directional Parallel Port
meeting the 1284 specification.
4.4.6 PCMCIA
Support for 2 separate CardBus slots (one type III or two type II stacked).
Individually accessed, dual-buffer implemented.
