Utility to print scancodes from DOS.
The purpose of this utility is getting the hardware scancodes as low level as possible.
Once launched it prints the scancode you get from the AT keyboard as long as ESC is not pressed.
Tools needed:
- Linux environment
- nasm to compile
- mtools to build floppy image
- mkisofs to build a bootable cd image
The freedos.img file contains a copy of FreeDOS 1.0 used to get a floppy disk image.
make images command will compile the program and build floppy
and cd image.
make qemu command will try to launch Qemu with the prepared CD
image. Quick way to test the program.
- write to a physical floppy (quite hard these days)
ddthe image into an USB stick and boot from the USB stick (I used add if=fdboot.img bs=1024 of=/dev/sdb)- use the image in a virtual environment
- burn the image on a physical CD and boot from it
- use the image in a virtual environment
