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.
