Overview
The Altos R300 system is a PCI bus based processor system built on an optimized baseboard. It comes with a single socket 478 processor slot utilizing an Intel® Pentium® 4 processor or Intel® Celeron processor with the Server Works GC-SL core logic chipset consisting of three distinct components: CMIC-SL, CIOBX2 and CSB5. The mainboard also integrates two Broadcom BCM 5703 10/100/1000 Base-T Gigabit Ethernet controllers solution for high performance network applications reducing power consumption.
For expandability, the system includes two 64-bit/100 MHz PCI-X bus slots and four DIMM slots that allow memory installation up to a maximum capacity of 4 GB.
For connectivity, the mainboard provides two USB (Universal Serial Bus) connectors, PS/2 interfaces for both mouse and keyboard, one UART serial port, one monitor port and two LAN ports.
For media storage, Altos R300 supports one slim-type CD-ROM drive, one slim-type floppy disk drive and a hard disk drive.
The system is fully compatible with Windows 2000 Server, SCO OpenServer 5.0.6, Unixware 7.1.1, NetWare 6, and Red Hat Linux 8.
Processors
The Intel® Pentium® 4 processor implements a new scalable system bus protocol. The system bus uses SST (Source-Synchronous Transfer) of addresses and data to improve performance for servers or workstations. With its on-die 512-KB level two (L2) cache implementing the Advanced Transfer Cache Architecture, the Intel® Pentium® 4 processor delivers higher performance than previous Pentium III processors while maintaining binary compatibility with all previous Intel® Architecture processors.
The mainboard supports FSB (front-side bus) speed up to 533 MHz.
