Derrick is a freeware hobby 32-bit protected mode operating system programmed in FASM. It is aimed for stability and speed and it can run on as little as a 80386 DX with EGA and 4 MB of RAM.
Currently, it can be run from a floppy disk and has a pretty stable and fast shell along with some interesting functions, like CPUID and CPU speed detection, temporary unreal mode switching for legacy disk access, three shell keyboard layout drivers, text-mode fonts loading on the fly, VGA SPIRAL demo, selection between 9-bit and 8-bit VGA dot-clock fonts and much more.
The current version is 0.0.2 and it has many improvements and bugfixes from 0.0.1, including a simple FAT12 file reading and a 32-bit DMA floppy driver (legacy BIOS INT 13h is used as a last resort).
Derrick is available in Slovak and English, thus both language versions fully support the Kamenický text encoding.
Programs
Currently, there is no support for user programs.
