$ ./compile.sh writeoverwrites the filesystem of
/dev/sdb-- be careful!
$ qemu-system-i386 os-imagecan be used for quicker testing, if recompilation is not necessary.
Testing is done with QEMU on a Lenovo T430. Development done on 64-bit Linux Mint Debian Edition with the standard GNU toolchain (GCC, LD, etc).
KevinOS currently loads a 32-bit C kernel in Protected Mode. It detects all interrupt calls and has basic PIT-handling code. Keypress detection for a standard laptop keyboard is more or less complete and the OS boots to a very basic shell. A basic text-buffer editor is available with
edit, and code in a pseudo-assembly language can be run with
exec. A very naive
malloc is in place, perhaps someday it'll be more than the bare minimum. The shell has a few odds and ends (beeps, PRNG, etc). A custom file system (KFS) is used, just for kicks.
