Reworked the 'skip detecting the slave if there was no master' code to be more complete (includes configurator drives) and to take into account int13h/25h calls. Some of the changes in my last checkin have been rolled back as a result (they are no longer needed). I did take a byte out of RAMVARS, but there was an alignment byte available for the taking. I also added a perl script for padding and adding the checksum byte to a binary image, which can be invoked manually or with 'make checksum'.
