I also have an IBC CADET 20 running CPM 2.2 with 1 8-inch floppy. I'd like to get the software which requires two drives to run on the 1 drive system by mapping all references to the second drive (B:) to calls to use the first (A:). Is this possible? The operating system on the 1 floppy system, incidently thinks that there are two drives and any reference to drive B: causes the disk controller to crash (the system hangs after trying to select drive B:). I don't know enough about CPM to patch this and SYSGEN a new system. Things are also difficult since the PUTSYS and GETSYS programs supplied with the system also assume that there is a drive B: and have hardcoded into the system references to this drive. The suppliers of the version of CPM (Integrated Business Computers of California) are on vacation for a month making it difficult to get a new version of CPM which assumes that there is only one drive. Can I patch the system into thinking this? And once I do it, can I hack something so that references to drive B: in software actually use drive A:. The reason why this is necessary is that the developer of the applications software which we are using won't havve a one-disk version out for another year and I want to get it working on our 1-disk system before that time. Help? -- Thanks in advance -- Eric
