# A disk for CosmOS. greet.sbx asks the system for everything it does rather than talking
# to the hardware itself, so loading and running it exercises the whole path: the loader,
# the vector table, the service handlers, and giving the machine back at the end.
#
# hello.sbx is the opposite case, and that is why it is here: it is the original
# hello.asm, written before any of this existed, and it still writes straight to port
# 0x00 rather than calling osPrintString. A program is allowed to reach past the system
# to the hardware, so something has to check that one still gives the machine back.

# notes.txt is there so that loading something that is not a program can be tried too.
