WARNING:

Some scripts need sudo to write directly to devices using `dd` and loopback interfaces

None of the scripts ask questions -- they WILL clobber your files

Read and understand the scripts before you use them and before you run `make`

Scripts:

Running make runs one or more of these scripts:

lo: sets up disk.img as a loopback device
unlo: tears down the loopback device set up by lo
createdisk: creates the disk image disk.img
formatdisk: formats disk.img using FAT12
copyboot: copies the bootloader bin/boot to the disk image
copystage2: mounts the filesystem on the disk image and copies the stage 2 loader

Requirements:

nasm
qemu

Building and running:

The following targets are available for make:

makedisk: creates the disk image and copies the files to it
runonly: runs the emulator with the disk image
full: compiles and assembles all files
run: same as full, but also runs the emulator
clean: removes all generated files
doc: compile the README and file comments; output in doc/

Notes:

when jumping to a location in memory, make sure it contains executable code, and not a string -- this has been a problem
