You can start with one of the 3 following flavors :

Start your computer with fd001.img. It will show the kernel version string and the kernel cmdline line. You can edit the cmdline. Most users can just press Enter.

The floppy is then loaded into memory (one dot each 64k) and you will be prompted to insert the next floppy, fd002.img. And so on up to fd005.img.

The base flavor will then start and you will be prompted to insert extra floppies for justx and core flavors. You can bypass this by using Q and Enter.
