Incidentally, if anyone fancies a go at reverse-engineering the binary, I can make available a FreeDOS HD image with the Watcom debugger/disassembler and the necessary DOS extender support setup. Unfortunately, I don't think I have the necessary low-level IDE nous to establish what it's doing to alter the timers in question....
