SCO OpenServer 5.0 documentation covers information on how to install the operating system in a virtual machine. For additional information about the operating system, refer to the instructions included in the installation media.

SCO OpenServer 5.0 documentation includes the following topics:

Installation Instructions

To install SCO OpenServer 5.0 in a virtual machine you can use the standard SCO OpenServer distribution CDs, the boot floppy/network method, or if your VMware product supports it, from a PXE server. The following installation instructions are for standard distribution CD.


Before you begin, verify that the following tasks are complete:

Read General Installation Instructions for All VMware Products.

Virtual disk recommendations

  • Minimum size - 1.5GiB for the SCO OpenServer 5.0 root disk.
  • biosgeom bootstring - Required for SCSI drives between 1 and 64GiB. (Not harmful to other drive sizes).
  • IDE virtual disks - SCO BTLD (wd boot-time loadable driver) for improved performance and reliability.
  • Special considerations for drive sizes: OpenServer 5.0.7 - wd BTLD is required for IDE disks larger than 128GiB (137GB).
    OpenServer 5.0.6 - Cannot use IDE disks that are 128GB or larger.

Supported virtual disks

  • BusLogic SCSI - Requires SCO blc BTLD 3.05.1 or later.
  • LSI SCSI - Requires SCO lsil BTLD 1.03.28 or later, LSI Logic lsil BTLD 1.04.09 or later.
  • LSI SAS - Requires LSI Logic lsil BTLD 1.04.09 or later.
  • IDE
  • Under 128GiB - no BTLD required.
  • 128GiB or more - 5.0.7 only, requires SCO "wd" BTLD.

Supported drivers

Note Floppy images must be renamed with a .flp extension to be accepted by ESX. The location of the floppy images on the LSI Web site do not appear to be static. If you cannot locate the floppy images at the addresses provided, try contacting an LSI representative.

Installation Steps

  1. Use the SCO OpenServer Release 5.0.7 install CD to install OSR5.0.6 and OSR5.0.7.
    The SCO OpenServer Release 5.0.6 install CD does not boot.
  2. Power on the virtual machine.
  3. Install the appropriate SCSI drivers:
    • IDE disk under 128GiB (137GB)
      No boot string required, press Enter.
    • IDE disk 128GiB (137GB) or larger (5.0.7 only)
      restart link="wd"
      When prompted to replace the driver, type r.
    • Buslogic
      restart link="blc" biosgeom
      When prompted to replace the driver, type r.
    • LSI Logic SCSI or SAS
      restart link="lsil" biosgeom
  4. Insert the appropriate installation disks when prompted.
    • For the OSR5.0.7 installation, continue with the inserted OpenServer Release 5.0.7 install CD.
    • For the OSR5.0.6 installation, switch to the SCO OpenServer Release 5.0.6 install image when the screen displays Identifying the installation media device at the top of the screen and Media device to be used: in the command prompt.
  5. Read and accept the license agreement.
  6. Accept the default CD-ROM type and controller and drive configuration.
    The Open Server 5.0 install checks for the drive type and defaults to the configuration.
  7. Follow the prompts to complete the installation.
  8. Turn off the bad block scan, which is on by default for IDE disks.
    The bad block scan is not necessary on a virtual disk.
  9. When selecting the mouse, press h to specify High Resolution Keyboard Mouse.
  10. Follow the prompts to complete the installation.
  11. (Optional) If you used biosgeom during the install, boot the guest with the defbootstr biosgeom command.

Install Maintenance Pack 5

After installing SCO OpenServer 5.0.7, install Maintenance Pack 5 (MP5).
Installation of MP5 is strongly recommended because it fixes several virtualization related issues such as enabling the mouse functionality in the X11 display. MP5 is not available for SCO OpenServer 5.0.6. Therefore, you cannot use X11 in that release.

Installation Steps

  1. Power on the SCO OpenServer 5.0.7 guest.
  2. (Optional) If you used biosgeom during the install, boot the guest with the defbootstr biosgeom command.
  3. Insert the SCO OpenServer 5.0.7 Maintenance Pack 5 CD in the CD-ROM drive.
  4. Install MP5 using the Software Manager.
    Note After MP5 is installed, the virtual machine boots normally without requiring biosgeom.
