ELKS v0.6.0

ELKS v0.6.0 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, using the NE2K network card, set for I/O address=0x300 and IRQ=12. See the Wiki HowTo for more information.
