Portal ending "Still Alive" as operating system or BIOS extension
https://www.youtube.com/watch?v=sB0hh7UAAfA
nasm, gcc and mtools are required to compile.
Simply run make
to compile everything (bootloader, code, floppy image and BIOS ROM).
Use the make floppy.img
command to assemble the floppy.img image.
Use the make stillalive.rom
command to build the BIOS ROM image file stillalive.rom.
Tests: make runqemu
launches qemu with pcspeaker.
To run on a real device simply flash image on floppy or even USB drive.
Or use make runrom
command to run the BIOS extension in the emulation.
Special thanks to @dlinyj for helping and testing!
