== Floppy image swapping == If you are booting from floppy using the BOOT command (but not yet the IMGMOUNT command), you can use the SwapFloppy key combination through the mapper to swap between floppies. This key combination is F11+CTRL+D by default, but can be changed through the mapper interface. == CD-ROM image swapping == IMGMOUNT can be used to attach multiple ISO images to a CD-ROM drive. At first, the first ISO image is presented to the guest as the CD-ROM drive. To emulate the act of removing the CD and putting in the next one, use the SwapCD key combination through the mapper. This key combination is F11+CTRL+C by default, but can be changed through the mapper interface. To provide a realistic CD change delay, CD switching is emulated as first the removal of the CD-ROM media from the drive, followed by a 4 second delay, followed by the emulation of inserting the new CD and waiting for the CD-ROM drive to spin up and read it. This delay is necessary for some OSes like Windows 95 who cannot detect CD changes if the changeover happens too fast.
