The BIOS is written in assembly language for maximum performance.

  • Backward compatible with legacy BIOS.
  • More than 10 times faster boot than competitors BIOS.
  • Small size, big functionality.
  • Boots any 16, 32 and 64-bit OS compliant with legacy boot.
  • The BIOS flash memory integrates a bootable file system with PDOS, drivers and applications.
  • The cost of fixed booting devices like eMMC or hard drives can be avoided by using the integrated PDOS.


The OS is written in assembly language for maximum performance.

  • Small size, big performance.
  • Available in legacy, single core and multi core versions.
  • Bridges the gap between micro controller RTOS and fullblown desktop.
  • No external dependency headache for applications and drivers.
  • Integrated support for legacy and USB devices, eMMC, SD card and the flash image drive emulated by PBIOS.
  • Native boot (no ram disk) support on all bootable devices.
  • PFAT algorithm creates faster and bigger FAT32 volumes (up to 2x faster reads and 3.3x faster writes).


The tools are based on Open Watcom, but enhanced with features improving productivity. The Open Watcom version is included for multi language and C++ support.

  • Builds applications and drivers for PDOS.
  • Builds applications for NT console mode.
  • Source code for the tools and run time library included.
  • Includes assembler, C-compiler, linker, debugger, object file disassembler and make utility.

The build system for our version of the tools and runtime libraries is a lot easier to understand than the overly complex system used by Open Watcom.

Functions in our runtime libraries written in assembly language use the simplified directives and language features in our assembler.
