Although this utility should not be your first option, you can use it to make a new empty CP/M disk image file.<br />
In case you decide to use it make sure you have a FAT aware DOS installed in your system. MAKEIMG makes use of the firmware calls CAS_OUT_OPEN, CAS_OUT_CLOSE and CAS_OUT_CHAR so your DOS must support them.<br />
Copy the files MAKEIMG.BAS and MAKEIMG.BIN to the root directory of your FAT formatted hard disk and make it your current drive. Run the utility with ''RUN"MAKEIMG"'' and don't hold your breath!<br />
Making an image file this way takes more than 1.5 hour for an 8MB file so literally... don't hold your breath.<br />
