build.bat can create the image if missing, split the shell into native, posix and win32, clean up the build by moving executables into directories, the bootloader is no longer responsible to resolve drivers, fix ResolvePath, every process gets a copy of a module (dll), the child always inherits the cwd, fix function exports in posix, add unlink and exit to posix, add path translator to win32, first bugcheck.
