2. Software Specifications
2.1.
Preface
The software engineering specification is a deployment from product marketing specification. It should outline
major tasks to be implemented in a specific model. For any model which has been defined from product marketing
division, there should have a product marketing specification comes out.
The purpose of this specification is to be an implementation guideline for engineers who are responsible for the
model. It intends to avoid ambiguity about function definitions so as to allow engineers to shorten their implementation
period.
The specification covers all the bundled software components which including BIOS, Micro-Controller, device
drivers and applications. The target Operating Systems will be Windows Vista. The device drivers and applications are
options based on per-customer’s requirements. The engineers should make sure that these drivers and application could
run without any difficulties on the target PC2001 model.
The readers of this specification are assumed to have enough experiences and knowledge to understand whatever
in the context. The specification will not intend to explain any detail of specific topic.
2.2. System Overview
2.2.1 System Memory
The System consists of DDR3 SDRAM memory. The BIOS will automatically detect the amount of memory
during the POST. But the total RAM size can not be used by user. (Must substrate by the size of the video shared
memory)
2.2.2 SATA
Which transfer mode will be set depend on the used devices, core chip SATA interface and BIOS supported. This
model’s BIOS support all the data transfer modes above, and it will auto detect and initialize it during POST.
2.2.3 Audio
The audio controller is integrated in ICH-M and through the HDA data line to external CODEC (ALC269)
to reduce the noise caused by PCB’s layout. However the H/W architecture is, the BIOS will recognize it as a PCI
device and initialize it in PCI bus initialization.
