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 XP. 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

System Memory

The System consists of DDR2 SDRAM memory. The BIOS will automatically detect the amount of memory during the
POST. But the total RAM size can be used by user must be substrated by the size of the video shared memory.
Enhanced IDE
Which transfer mode will be set depending on the used devices, core chip IDE 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.
Audio
The audio controller is integrated in ICH-M and through the HDA data line to external CODEC (ALC861) 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. The PCI legacy audio mode is not to be supported.
Modem
The system can use all of the modem that is HDA compliance and the MDC form factor. During POST need to detect the
existence and set proper registers in south bridge.
PCMCIA
Windows XP Home SP2/ Professional SP2
PCI Device
All the PCI devices will occupy the system resources, such as I/O, Memory and IRQ, especially the IRQ assignment is
relative to H/W and system arrangement. The following will list all PCI devices:
compliance.
