2. Chipset on this Mother Board
The Motherbaoard use the Chipset of SiS530 & SIS5595 where SIS 530 is
fuinction for Host, PCI, 3D A.G.P. Video/Graphics & Memory Controller
and the SiS5595 is function for PCI SYSTEM I/O.
The SiS530/5595 chipset, provides a high performance/cost index Desk-
top/Mobile solution for the Intel Pentium P54C/P55C, AMD K5/K6/K6-II,
Cyrix M1/M2 and other compatible Pentium CPU with 3D A.G.P. VGA
system.
The Host, PCI, 3D A.G.P. Video/Graphics & Memory Controller, SiS530
integrates the Host-to-PCI bridge, the PCI interface, the L2 cache control-
ler, the DRAM controller, the high performance hardware 2D/3D VGA con-
troller, and the PCI IDE controller.
The Host interface supports Synchronous/Asynchronous Host/DRAM clock-
ing configuration to eminently improve the system performance and DRAM
compatibility issues.
The L2 cache controller can support up to 512 KB P.B. SRAM, and the
DRAM controller can support SDRAM memory up to 768 MBytes.
The built-in fast PCI IDE controller supports the ATA PIO/DMA, and the
Ultra DMA33 function that support the data transfer rate up to 33 MB/s. It
provides the separate data path for two IDE channels that can eminently
improve the performance under the multi-tasking environment.
The A.G.P. internal interface is supported for integrated H/W 3D VGA con-
troller. The integrated VGA controller is a high performance and targeted at
3D graphics application. In addition, the integrated 3D Video/Graphics con-
troller adopts the 64bits 100MHz host bus interface high technology to im-
prove the performance eminently. To cost-effective the PC system, the share
system memory architecture will be adopted and it can flexibly using the
2MB, 4MB and 8MB frame buffer size from programming the system BIOS.
To enhance the system performance, SiS530 also supports the local frame
buffer solution and memory sizes can support up to 8MB with SDRAM.
