Overview
The Acer Altos R500 system is a PCI bus based dual processor system built on an extended ATX baseboard. It comes with two socket 370 processor slots utilizing two Intel® Coppermine-T or Tualatin® processors integrated with the Server Works RCC chipset. The dual- channel SCSI architecture supports Ultra 160/m SCSI with bandwidth of up to 160 MB/s for each channel. The mainboard also integrates the Intel® 82550 10/100 Mbps PCI Ethernet chipset that supports WOL (Wake on LAN) for better remote site management.
For expandability, the system includes two 64-bit/66 MHz PCI bus slots and four DIMM slots that allow memory installation up to a maximum of 4 GB.
For connectivity, the mainboard provides two USB (Universal Serial Bus) connectors, PS/2 interface for both mouse and keyboard, one UART serial port, and four LAN ports.
For its storage features, Altos R500 supports one slim-type CD-ROM drive, one slim-type floppy disk drive and three hot-swappable SCSI hard disk drive.
The system is fully compatible with MS-DOS V6.X, Novell Netware, SCO UNIX Openserver SCO, Unixware, Red Hat Linux 6.X., Sun Solaris, Windows NT 4.0 and Windows 2000 Professional.
Processors
The Intel Tualatin processor implements Dynamic Execution performance, a multi-transaction system bus, and Intel MMX media enhancement technology. It also offers Streaming SIMD (Single Instruction Multiple Data) Extensions - 70 new instructions enabling advanced imaging, 3D, streaming audio and video, and speech recognition applications. With its on-die 512-KB level two (L2) cache implementing the Advanced Transfer Cache Architecture, the Tualatin processor delivers higher performance than previous Pentium processors while maintaining binary compatibility with all previous Intel Architecture processors.
The mainboard supports 100 or 133 MHz GTL+ host bus frequencies for Tualatin processors running at 1 GHz and above.
