General System Description

1.1. HARDWARE SPECIFICATIONS A. CPU N241S1 Use INTEL Celeron & Pentium III Processor for the PGA370 Socket . Celeron Processor running from 533A MHz to 733 MHz. Pentium III Processor from 500 MHz to 1 GHz. These CPU are integrated high performance 16 KB instruction and 16 KB data, nonblocking, level one cache. The CPUs also integrated level two cache(128 KB for Celeron and 256 KB for Pentium III) with 32-bit applications running on advanced 32-bit operating systems. The Celeron Vcore running at 1.65V(CPUID 0683h),1.70V(CPUID 0686h) ,Vtt at 1.5V and Vcmos at 2.5V. Pentium III Vcore running at 1.7V, Vtt at 1.5V and Vcmos at 2.5V for 1 GHz. The power circuit also support the autoset of Vcc core by the VID0-3 signals from CPU. Both of CPUs support MMXtechnology. B. CORE LOGIC N241S1 uses SIS630S single chipset as core logic . The single chipset, SiS630S, provides a high performance/low cost Desktop solution for the Intel Slot 1 and socket 370 series CPUs based system by integrating a high performance North Bridge, advanced hardware 2D/3D GUI engine, Super-South bridge and an AGP4X Slot.

Furthermore, SiS630S provides powerful hardware decoding DVD accelerator to improve the DVD playback performance. In addition to providing the standard interface for CRT monitors, SiS630S also provides the Digital Flat Panel Port (DFP) for a standard interface between a personal computer and a digital flat panel monitor. To extend functionality and flexibility, SiS630S adopts Share System Memory Architecture which can flexibly utilize the frame buffer size up to 64MB. The “Super-South Bridge” in SiS630S integrates all peripheral controllers/accelerators /interfaces. SiS630S provides a total communication solution including 10/100Mb Fast Ethernet for Office requirement. SiS630S offers AC’97 compliant interface that comprises digital audio engine with 3D-hardware accelerator, on-chip sample rate converter, and professional wavetable along with separate modem DMA controller. SiS630S also provides interface to Low Pin Count (LPC) operating at 33 MHz clock which is the same as PCI clock on the host, and dual USB host controllers with six USB ports that deliver better connectivity and 2 x 12Mb bandwidth.The built-in fast PCI IDE controller supports the ATA PIO/DMA, and the Ultra DMA33/66/100 function that supports the data transfer rate up to 100 MB/s. It provides the separate data path for two IDE channels that can eminently improve the performance under the multi-tasking environment. C.

2.2 Mechanical Buttons and Switch Definition 2.2.1 Power on/off button 1. If the system is in S0, S1 or S2 state, pressing the power button will transit the system to S4 (Suspend to Disk) or S5 (Soft-off) state depending on the “Power button function” setting in the BIOS Setup menu. 2. If the system is in S4 or S5 states, pressing the power button will awaken the system into S0 states. 3. If the power button is pressed for more than four seconds, a power button over-ride event is generated and the system will be put into S5 (Soft-off) state. 2.2.2 Cover (Lid) Switch When LCD cover is closed, this Lid switch is triggered and an SMI/SCI is generated to put the system into ‘Standby Mode’ or ‘Suspend to Disk’ mode depending on the “Cover Switch” setting in the BIOS Setup menu. 2.2.3 Hot Function Button When this button is pressed, the system will launch Microsoft Internet Explorer and connect to Uniwill’s Web Site.
