IBM PS/2 Reference, Diagnostic & Option Disks

This is a fairly complete archive of files for the IBM PS/2 series of personal computers. Following disk images are available for most systems and options:

  • Reference Disk (refdisk) - Required to configure MCA based systems.
  • Starter Disk - Required to configure ISA based systems.
  • Diagnostic Disk (diag disk) - Can be used to test the system unit and peripherals. Typically accessed through the corresponding Reference Disk.
  • Option Disk - May be required when installing a new option. For MCA adapters it also contains the corresponding ADF files (Adapter Description Files).
  • Flash Update Diskette - Allows you to update system/adapter firmware (BIOS). This feature is only available on the late PS/2 systems and adapters.

Note: The disk images on this page are in RAW format (.IMG/.IMA - uncompressed image) to achieve the best possible compatibility and flexibility. This format can be processed by many different utilities for many different operating systems (i.e. WinImage for Windows).

Legal Notice: Feel free to mirror and/or use these files anywhere/however you like, as long as you don't charge for it or violate the IBM License terms (license.txt) in any way.
