We are proud to announce ELKS v0.8.0 released on September 24, 2024.
Thank you to all that have contributed and are using ELKS, and enjoy!

ELKS v0.8.0 Downloads

Prebuilt disk images for floppy and hard disks are downloadable below from Github Assets for this release.
These images can be used to boot from PC/XT/AT or PC-98 hardware, or emulators, such as QEMU or dosbox-x.
The images are built with network support by default, supporting NE2K, WD and 3Com NICs.
See the Wiki HowTo for more information.

ELKS v0.8.0 Enhancements

Thank you to all who contributed to ELKS enhancements, bug identification, testing and fixes.
The system continues to be very stable, with no known crashes and long uptimes.

Major Enhancements

Major additions include support for:

  • Application development using the Open Watcom C compiler and OS/2 executable format, allowing for
    large multisegment programs to run, using all available memory if necessary. Doom was recently ported.
  • Add NE2K, WD and 3COM networking support to default build.
  • Compressed executables by default allowing for many more applications per floppy image.
  • Asynchronous I/O was added to the kernel along with @Mellvik's Direct Floppy disk driver, which
    allows for other applications to run while waiting for floppy disk I/O.
  • All kernel resources dynamically adjustable at boot, allowing for the kernel heap, tasks,
    inode and file allocations to be adjusted as required for min or max memory usage.
  • Increased symbolic debugging capabilities with enhancements to the symbolic disassembler,
    system call and function tracing capabilities within running applications.
  • Rewrite of L1/L2 buffer cache operation allowing for faster operation using fewer buffers.
  • Precision timing routines and removal of most all long division in the kernel and C library for
    fastest operation and better elapsed time measurements.
