Which will supports the different levels of Pentium III CPU with FC-PGA package. Those are Pentium III 600/650/700/750/800 MHz, and Celeron 600/633/667/700/733 MHz . This system is based on PCI architecture and is fully compatible with IBM PC/AT specification, which have standard hardware peripheral interface and support Intel Pentium III with FC-PGA package. The power management complies with Advanced Configuration and Power Interface (ACPI) 1.0. It also provides easy configuration through CMOS setup, which is built in system BIOS software and can be pop-up by pressing F2 at system start up or warm reset. System also provides icon LEDs to display system status, such as AC Power indicator, FDD, HDD, NUM LOCK, CAP LOCK, SCROLL LOCK, SUSPEND MODE and battery present, capacity & charging status. It also equipped with LAN, FIR, USB port, 3D stereo audio functions. The memory subsystem supports 64MB on board SDRAM, one 144pin DIMM socket for upgrading up to 192 MB of DRAM using SDRAM DIMM module. The SiS 630 integrates the north bridge chip, super south bridge and the real 128-bit 3D graphics accelerator all into one single chip. It provides 10/100M Fast Ethernet, 3D Positional Audio, Advance H/W DVD playback and 2D/3D graphics engine. 2 7521 N/B MAINTENANCE The TI 1225 cardbus controller supports PCMCIA and CARDBUS. The National Semiconductor PC97338 Super I/O controller integrates the standard PC I/O functions: floppy interface, two FIFO serial ports, one EPP/ECP capable parallel port, and support for an IrDA 1.1, 1.0 and sharp ASK compatible infrared interface. To provide for the increasing number of multimedia applications, an CODEC CS4299 is
