OpenServer 5.0.7


  • Supports all uni- and multi-processor configurations compatible with Intel Multiprocessing Specification (MPS) version 1.1 or 1.4
  • Intel Pentium, Pentium II, Pentium III, Pentium 4, Celeron and Xeon
  • AMD K5, K6, Duron, Athlon XP, Athlon MP
  • Many Cyrix processors

NOTE: Customized versions of OpenServer will install and operate some applications on 386 or 486 class systems.

I/O Bus

  • Industry Standard Architecture (ISA)
  • Extended Industry Standard Architecture (EISA)
  • Micro Channel Architecture (MCA)
  • Peripheral Component Interface (PCI)
  • Universal Serial Bus (USB) 1.1 and 2.0 devices, including keyboards, mice, mass storage devices, and USB hubs


  • 64 MB recommended for most system configurations
  • 4 MB for customized systems
  • 128 MB recommend for desktop systems

Disk Space

  • Minimum of 400MB for the Host System
  • Minimum of 550MB for the Desktop System
  • Minimum of 600MB for the Enterprise System (add 500MB for Internet Services
  • Minimum of 15MB (30MB is preferred) for the boot filesystem (/stand)
  • 1 to 1.5 times as much space for swap as there is RAM
  • 17 MB per foreign language supported.

NOTE: OpenServer supports EIDE disks as large as 137 GB, and SCSI or USB disks as large as 539 GB either singly or in RAID arrays. Legacy formats such as ESDI are also supported, and tailored, specific purpose versions of OpenServer can be loaded in less than 100 MB of disk space. OpenServer supports 4 disk partitions per drive with up to 7 filesystems per partition. Each filesystem may be as large as 1 TB. The maximum file size is 2 GB.


  • 600x800 VGA with 256 colors (recommended minimum)
  • 1600x1200 with 24-bit color (maximum)

NOTE: OpenServer will work with a monochrome display on a 25x80 character screen with no video card is available when the system console is directed through a serial port to a character terminal.


  • OpenServer supports most 1Gbps, 100Mbps, 10Mbps and Token Ring NICs, and it does not require a network to function
  • A simple Host System does not need a NIC (Network Interface Card) installed
  • OpenServer supports TCP/IP, IPX/SPX, NetBEUI (with optional AFPS product), NetBIOS, SMB, NFS, PPP, Microsoft Network Neighborhood (with optional Merge product) and serial line protocols.

Pointing Device

  • Scrolling (wheel)
  • Infrared
  • Touchpad
  • Roller ball

NOTE: Pointing devices available in serial, bus, PS/2 and USB configurations. Please note that no pointing device (mouse) is required to operate an OpenServer system, unless using the graphical desktop.


  • All common keyboards, including USB, are supported including many foreign language keyboards.
  • A keyboard is required to install OpenServer, but does not need to be present for OpenServer to function. (If a serial terminal is being used for a console then the system keyboard does not need to be present even during installation.)

Off-line Storage

Many types of off-line storage devices are supported by OpenServer, including:

  • All densities of 5 1/4 and 3 1/2 floppy drives
  • QIC, DAT, 8mm, and DLT tape drives
  • Floptical drives
  • LS 120 and 240 drives
  • Jaz and Zip drives
  • All speeds of SCSI, ATAPI (EIDE), and USB CD and DVD readers and writers. To use a CD or DVD writer a writer utility is necessary. A free CD writer is available in the Skunkware software collection. Other CD and DVD writer utilties are available from third parties.

NOTE: no offline storage device is required by OpenServer to function, however either a bootable CD-ROM drive, or a floppy drive and a non-bootable CD-ROM drive is required to install the operating system.


  • Many audio devices are available for use with OpenServer when the Open Sound System (OSS) drivers from 4Front Technologies are installed. The drivers are available for an additional cost directly from 4Front, and come with a selection of audio playback, recording, and equalization utilities.
  • When used in conjunction with the Merge add-on product, many of the Microsoft Windows audio and multimedia playback utilities can be used, however acceptable performance may not be possible with a CPU any slower than 350MHz.

Other Hardware

Many other peripheral devices are supported by OpenServer, including:

  • Many modems (internal and external) operating from 56.2Kbps down to the slowest known (Note: win-modems are not supported.)
  • Most printers ranging from common black and white or color inkjets to high speed departmental laser printers (Note: win-printers are not supported.)
  • Most monitors in all sizes ranging from monchrome to full color high resolution models
  • Many multiport serial/parallel setups (includes remote consoles, but generally requires third party drivers)
  • PCI serial and parallel ports

NOTE: All of the items listed under "Other Hardware" are optional and not required by OpenServer to install or execute most basic functions. For a complete list of supported hardware, see Xinuos's Certified and Compatible Hardware List.
