OS/2 Prototype Disks

Below are some interesting pre-1.0 (or 1.0-based) OS/2 revisions we have unearthed. They provide an early glimpse of OS/2 when it was still a work-in-progress. Not all of the disks run properly in PCjs yet, but we're working on it.

  • OS/2 CP-DOS Boot Disk (v7.68)

    The OS/2 CP-DOS Boot Disk (v7.68) contained a pre-1.0 version of OS/2 built on October 22, 1986.

  • OS/2 SIZZLE Boot Disk (v7.68.18)

    The OS/2 SIZZLE Boot Disk (v7.68.18) contained a pre-1.0 version of OS/2 built on January 7, 1987, which was based on an interim source code fork known as "SIZZLE", the code-name for a collection of changes intended to improve overall OS/2 performance.

  • OS/2 SIZZLE Boot Disk (v7.68.18 DEBUG)

    The OS/2 SIZZLE Boot Disk (v7.68.18 DEBUG) was largely identical to the previous disk, with the exception of a DEBUG kernel (with built-in debugger) and a different assortment of tools.

  • OS/2 FOOTBALL Boot Disk (v7.68.17)

    The OS/2 FOOTBALL Boot Disk (v7.68.17) contained a prototype version of OS/2 from February 1987 that was designed to test two important new features of the Intel 80386 processor: paging and V86-mode. This prototype was forked from pre-1.0 OS/2 sources, and the only hardware it supported was the Compaq DeskPro 386-16.

  • OS/2 FOOTBALL Boot Disk (v4.41.00)

    The OS/2 FOOTBALL Boot Disk (v4.41.00) contained an updated FOOTBALL prototype. It was built in December 1987, using final OS/2 1.0 sources merged with assorted FOOTBALL changes, and although it was originally assigned version number 1.3, this version of OS/2 would ultimately become 2.0.

  • OS/2 1.0 Debugger Boot Disk

    The OS/2 1.0 Debugger Boot Disk contained a version of OS/2 1.0 built on October 12, 1988, which included the built-in kernel debugger used by Microsoft and IBM for internal development, along with a rudimentary program selector. For more details, see the OS/2 1.0 blog post.
