  • Perix Operating System - 16/32 Bit Icon

    Perix Operating System - 16/32 Bit

    Perix is a 16/32 protected mode kernel, bootable and capable of running without an operating system. It is written in Turbo Pascal 7.0 for DOS, Delphi 7.0, Pascal Pro, Virtual Pascal v2.1, TASM and JWASM. Turbo pascal version can be used as kernel on its own, or as a second stage loader to external programs. I would like to announce, that the first attempt to put the Delphi 64bit to work was successful. As soon as possible I will place at the disposal a very small 64bit kernel version.
