CLEAN DOS (C) 1994 SIMON COOKE ______________________________ This is a DOS patch for SAMDOS that, amongst other things, will tell you system information (do you have a SAMBus connected? Do you have external memory? Have you done that naughty trick with the SHIFT key on RESET to get your machine to be a 256k one?). It will also clean up your system by resetting all system vectors to zero. Unfortunately I haven't got it cleaning out the ALLOC table for extra screens yet, as the jump table is a bit messy (or so it seems to me). It does clear out most things though: It will set all vectors back to normal (except the NMI one, which may be different for different ROMs... if I get the other ROMs, I'll alter it so that it does set it back to normal). It doesn't reset the HEAP back to normal (yet). There was another version which added the RESET key combinations, but it had a habit of crashing when used with programs that illegally used the heap (like a lot of mine.... gulp). Also I'm going to see what I can do about putting in an optional "keyboard buffer full" beep into the key scan routines... Who says you can't have fun fiddling about? (c) Entropy/Simon Cooke 1994 May be spread as PD as long as you don't hack the code and change the copy- rights... anything else seems to be fine to me :)
