A lot of software (like games and demos), and even some hardware like cartridges, do not
correctly handle a second drive connected to the IEC bus (especially the IEC 2 SD drive),
resulting in unexpected behavior. This is not a flaw of the 1541 Ultimate, but rather a
limitation of the software! If you are experiencing problems with software, you should try
to disable the IEC 2 SD Drive. To deal with this kind of problems the INIT and KILL
commands are at you disposal, or use the Configuration menu.
A lot of cartridges and kernels allow you to send a command to any drive using a special
character. For example, the Action Replay family of cartridges will allow you to use
@KILL1, instead of having to type the full blown BASIC commands mentioned above.
